MIS Model
Management Information Systems is one of the most dynamic fields of study in
academia. In comparison to other fields of study, it is a young, applied research
discipline. However, what exactly is MIS? Elements of MIS may include computerbased systems, networks, people, processes, data, and software. This paper proposes that
MIS is a new and previously unknown junction of reference disciplines. Many reference
disciplines tend to conduct more basic research while MIS performs more applied
research. The reference disciplines for MIS include Electrical and Computer
Engineering, Computer Science, Management and Organizational Behavior, Systems and
Industrial Engineering, Cognitive Psychology, and Economics.
How does MIS relate to reference disciplines? Some reference disciplines, such as
accounting, management, and economics, are related to business and compete more
directly with MIS for resources and credibility. However, MIS does something no
reference discipline does, or it wouldn't exist at all! As will be shown by the following
review of major issues, important theories, top papers, key researchers, and future MIS
research areas, MIS integrates many disciplines.

Overview of MIS
Artificial Intelligence
Important Theories and Trends
The original goal of AI (Artificial Intelligence) is to understanding and implementing
intelligence. Herbert A. Simon further paints a broad picture of AI as a discipline
constantly pursuing computational creations that challenge the uniqueness of biologically
grounded intelligence. John McCarthy gives 12 branches of AI, namely, logic, learning,
searching, representation, pattern recognition, inference, common sense knowledge,
planning, epistemology, ontology, heuristics, and genetic programming.
The controversies of AI fall into the following three major categories:
(1) Knowledge representation and reasoning:
A longstanding view of the role of logic in AI is that logic is an abstracted, hence simpler
form of natural language. Thus it provides an ideal medium for a first approximation.
This view is attacked with a variety of arguments [Wolfgang Bibel].
Drew McDermott argues that AI’s success arises not from sophisticated representation
and reasoning methods, but rather from simple representations and tractable algorithms.
Another controversy concerning knowledge representation and reasoning is whether
intelligence is derived primarily from logical reasoning or from knowledge. The
controversy is not about whether common sense is necessary but how much it should be
built into the logic or into the knowledge base [Bruce Buchanan].
(2) Machine learning:
The problem is whether computers should attempt to model how people or whether
computers should follow methods did that no person things that no person could ever do
and that might actually improve on people. [Roger Schank]. Oliver Selfridge suggests
that AI software should be more concerned with being changeable than with satisfying
specifications.
(3) The practice of AI:
There is a conflict between methodology-driven and phenomenon-driven research in AI,
as well as the conflict between quantitatively valuable research and the more creative and
often less quantifiable research necessary for a constantly growing discipline [Jerry
Feldman].
Future Research
(1) The decline in complex knowledge representations and the success of prepositional or
probabilistic competitors [Drew McDermott];
(2) Machine learning and automation of deductive reasoning [Donld Michie].
2
(3) Building intelligent systems that will let people access and utilize enormous amounts
of information generated by modern societies in various forms for making informed
decisions [Ryszard Michalski].
(4) Multi-Agent Systems, application for data mining, knowledge Management.

Key Papers
Computer Machinery and Intelligence, A. M. Turing
This paper address the question of “Can machine think?” Turing takes a behavioristic
posture relative to the question. The question is to be decided by an unprejudiced
comparison of the alleged “thinking behavior” of the machine with normal “think
behavior” of human beings. hw propose an experiment-commonly called “Turing test”-in
which the unprejudiced comparison could be made. Though the test has flaws, it is the
best that has been proposed to date.

Artificial Intelligence, 1996, pp 1-24.
Understanding the natural and the artificial worlds, The psychology of thinking:
embedding artifice in nature, The science of design: creating the artificial, The
4
architecture of complexity. "Artificial" denotes systems that have a given form and
behavior because they adapt to their environment in reference to goals or purposes.
Some Philosophical Problems from the Standpoint of Artificial Intelligence, John
McCarthy and Pat Hayes, 1969 in Machine Intelligence 4.
It is the basic paper on situation calculus. This paper looks at some philosophical issues
concerning artificial intelligence, which includes how the concept of ability and belief
could be given formal definition in the metaphysically adequate automaton model and
indicates the correspondence between these formal concepts and the corresponding
commonsense concepts, construction of epistemologically adequate system. Instead of
given formal definitions, formal notions are introduced by informal natural language
descriptions with examples of their use to describe situations and possibilities for action
they present.
Intelligence without Robots, oren Etzioni, AI Magazine, Winter 1993, vol. 14, no. 4, pp.713.
In his recent papers, entitled "Intelligence without Representation and "Intelligence
without Reason," Brooks argues for studying complete agents in real-world environments
and for mobile robots as the foundation for AI research. This article argues that, even if
we seek to investigate complete agents in real-world environments, robotics is neither
necessary nor sufficient as a basis for AI research. The article proposes real-world
software environments, such as operating systems or databases, as a complementary
substrate for intelligent-agents research, and considers the relative advantages of software
environments as test beds for AI.

CMC/HCI/Communication/Visualization
Introduction
Computer-mediated-communication (CMC), human-computer-interaction (HCI),
communication and visualization of design interface impacts the research within MIS.
This body of literature’s research tries to understand how humans interact and
communicate with one another using different computerized technologies. It is important
to understand how people interact with the computer and with one another in order to
better understand prototypes that MIS researchers may design. The communication
amongst these modes needs to also be taken into consideration as research has suggested
that decisions, communication, and usage of technologies differ via computers than in
face-to-face (FTF) settings.
Most Important Theories
Some important theories, hypothesis, and models to come from this area of research are
Interactivity Model, The Postrepresentational Model (HCS), Artificial Morality, SIDE
Theory.
Key Issues, Conflicts, And Major Research Problems
The current key issues in this area are the visualization of dynamic processes in network
and the interaction metaphor for dynamic processes. It consists of the integration of
tactile sensing, vision, and sound.

Biocca, F., Kim, T., and Levy, M. R. (1995). Chapter 1: The vision of virtual reality. In
F. Biocca’s Communication in the age of virtual reality (pp. 3-14). Hillsdale, NJ:
Erlbaum.
The chapter looks at if virtual reality would make for a better medium of communication.
They suggest that VR is the ultimate form of media technology. If this is the case, MIS
researchers need to look at different areas of design integrating VR.
Daft, R. L. and Lengel, R. H. (1986). Organizational information requirements, media
richness and structural design. Management Science, 32(5), 554-571.
The article primarily discusses that uncertainty and equivocality are the primary factors
why organization processes information. It attempted to integrate equivocality with
uncertainty and argue that structural characteristics are used to help organization to cope
with these two factors. The authors proposes models that show how organization can be
design to meet the information needs of technology, interdepartment relations, and the
environment.
Galagher and Kraut. (1994). Computer mediated communication for intellectual
teamwork. Information Systems Research, 5(2), 110-138.
This article analyzes contingency theory’s prediction that using computer mediated
communication to accomplish complex collaboration work will be difficult, especially for
tasks that require interactive, expressive communication. The author conducted
experiments with sixty-seven three person groups of students that completed two
collaborative writing projects under either computer only, computer plus phone or face to
face communications. The findings tend to confirm the contingency hypothesis regarding
the difficulty of accomplishing work that involves ambiguous goals, multiple
perspectives, and information that is susceptible to multiple interpretations without an
interactive multiperson communication medium, such as face-to-face meetings.
Kramer, R. and Tyler, T. (1996). Trust in organizations: Frontiers of theories and
research. Sage Publications
Laudauer, T. K. (1995). The troubles with computers: Usefulness, usability, and
productivity. MIT Press, Cambridge, MA.
The book explains and illustrates why computers are in trouble and why investments on
computing have not resulted in productivity. The author argues that the conditions are the
result of the fact that computers rarely improve efficiency of the information work
because they are too hard to use and do too little that is sufficiently useful. The author
proposed that the use of user centered development technique through task analysis,
iterative design, trial use, and evaluation, computer systems can be powerful tools.
Reeves and Nass. (1996). The media equation : How people treat computers, television,
and new media like real people and places. Cambridge University Press, Cambridge, UK.
The book involves numerous studies conducted by Reeves and Nass to understand how
people treat media such as computers, television, and other new technologies. They found
that people tend to have biases and opinions about the medium they are interacting with.
Changes in voice or display can result in the changes of attitudes towards the mechanism
9
they are interacting with. While there has been much academic discussion as to whether
or not the results found in the book are correct, it poses an area of research that had not
been looked at before that MIS researchers should be aware of. If there is truth to the
findings of people, then how MIS designs systems needs to be wary of the findings. If
people respond in different ways to small characteristics such as male versus female
voice and credibility attributions of interactions that ensue, then small design issues of
choosing voice automated systems can impact user satisfaction.
Sproull, L. and Kiesler, S. (1991). Connections: New waysof working in the networked
organization. MIT Press, Cambridge, MA.
Within the book, the authors demonstrate the effect of new technologies in organizational
communication and how people's thinking and working habits change in lieu of these
technologies. They give guideline criteria as to how people utilize technology, such as email, to form better networks and how visions and goals of the organization should in
turn be shaped. The book gives a good basis for understanding users within an
organization, what impact inventions can have on a user, and the different characteristics
of how people use the technology. Since MIS involves organizations and communicative
functions within, understanding how their prototypes and designs effect an organization
and its people is beneficial. When designing prototypes, audience characteristics need to
be taken into consideration.
Walther, J. (1995). Relational aspects of CMC: Experimental observations over time.
Organization Science, 6( 2), 186-203.
This article looked at computer conferencing and its effects on people's perceptions of the
relational messages found within. Dr. Walther suggests that past research about CMC
relational research is inconsistent and that some areas of interpersonal communication are
actually better when done over CMC than in face-to-face groups. It is important for MIS
researchers to understand when it is better to engage in group work over CMC versus
face-to-face to achieve better results in their proposed designs for task related situations.

Computing Policy
Introduction
The discipline is not well established till present. Papers in this field can be found in
many journals such as Communication of the ACM, Computers andSociety, Science,
Technology and Human Values, and etc. But there is no key journal for this filed, which
is also true for debate about the social roles of information technology as mentioned in
Rob Kling’s book, Computerization and Controversy: Value Conflicts and Social
Choices.
The discipline is closely related to research in social and ethics issues of computing,
which is come from the close relationship between social science, ethics and policy
science. Rob Kling divided theoretical perspectives adopted by Social Analysts of
Computing into two major categories, and Policy research was included into this scheme.
Social Analysis of Computing
Systems Rationalism
Rational
Structural
Human Relations
Segmented Institutionalism Interactionist
Organizational Politics
Class Politics
The suitable definition for “policy” from Webster for this domain is “a high-level overall
plan embracing the general goals and acceptable procedures especially of a governmental
body ”. Policy issues research is different from social and ethics issues research. Social
and ethics research focus on the roles of information technology in social or ethical
settings, and policy research focuses on the high-level relationship between different
participants/actors in the social environment, and power and goal are the key issues.
Government is usually involved in research of this discipline, and because of the
difference between different countries on social organization and government roles,
international view should be taken to describe the who picture.
Most Important Theories
Theories in this field is from economics, policy and technology, and it is hard to address
key theories for this not well defined field.

This paper examines the relationship between the use of computer-based systems and
transformations in parts of the social order. Answers to this question rest heavily on the
way computer-based systems are consumed -- not just produced or disseminated. The
discourse about computerization advanced in many professional magazines and the mass
media is saturated with talk about "revolution" -- and yet, substantial social changes are
often difficult to identify in carefully designed empirical studies. The paper examines
qualitative case studies of computerization in welfare agencies, urban planning,
accounting, marketing, and manufacturing to examine the ways that computerization
alters social life in varied ways: sometimes restructuring relationships and in other cases,
reinforcing existing social relationships. The paper also examines some of the theoretical
16
issues in studies of computerization, such as drawing boundaries. It concludes with some
observations about the sociology of computer science as an academic discipline.

Database
Introduction
Database systems continue to be a key area in many fields including business, computer
science, and engineering. Representing knowledge within a computer is one of the central
challenges of the field. Database research has focused primarily on this fundamental
issue. Many universities have faculty investigating these problems and offer courses that
teach the concepts developed by this research program. Today, the Internet is considered
by many to be one large database. Database research has migrated from a study of data
modeling for a centralized data store, to studies on highly distributed, heterogeneous,
dynamic, and enormous collections of multimedia data.
Key Theories
E.F. Codd and Peter Chen developed several early key theories in database research. E.F.
Codd developed the relational model for databases and Peter Chen introduced the entityrelationship model. These theories are covered in greater detail under the respective
researcher. More recent database theories adopt an object-oriented design and respond to
the effects of distributed databases, such as the Internet, and larger and faster data storage
capabilities.
Key Issues
There continues to be active and valuable research on representing and indexing data,
adding inference to data search, compiling queries more efficiently, executing queries in
parallel, integrating data from heterogeneous data sources, analyzing performance, and
extending the transaction model to handle long transactions and workflow (transactions
that involve human as well as computer steps). The availability of very-large-scale
(tertiary) storage devices has prompted the study of models for queries on very slow
devices.
Future Research
There is great interest and direction in unifying object-oriented concepts with the
relational model. New data types (image, document, drawing) are best viewed as the
methods that implement them rather than the bytes that represent them. By adding
procedures to the database system, one gets active databases, data inference, and data
encapsulation. This object-oriented approach is an area of active research in academe and
in industry. Continuing research is creating the ideas and training the people for the next
product generation. As storage devices continue to become larger and faster, new data
models will need to be developed to efficiently represent and process the data. The
development of ultra-high-density data storage such as holographic data storage is a
promising innovation in the field of database research.

377-387 (1970)
Future users of large data banks must be protected from having to know how data is
organized in the computer (the internal representation). Activities of users at terminals
and most application programs should remain unaffected when the internal representation
of data is changed and even when some aspects of the external representation are
changed. Modifications to data representation will often be needed as a result of changes
in query, update, and report traffic and natural growth in the types of stored information.

A data model, called the entity-relationship model, is proposed in this model. This model
incorporates some of the important semantic information about the real world. A special

E-Commerce
Introduction
Electronic commerce technologies are the fundamental infrastructure for commerce,
communication and communities in the digital age. Basic advancements in engineering
and computer technologies are spawning an astounding array of new applications which
extend the use of computers and networking into all aspects of economic, social and
political activities. While the vision of a networked, digital society is most compelling,
the continuing process of technological developments and applications poses a serious
challenge in defining research priorities that sufficiently address both the emerging vision
of the future and the need to foster and impart basic scientific body of knowledge. The
goal of basic research in electronic commerce is to foster advances in related areas, to
maximize the synergistic, to increase interdisciplinary understanding of how electronic
commerce technologies affect market processes and welfare, and to assure that electronic
commerce applications achieve their promised efficient outcomes.
Key Issues, Conflicts, and Major Research Problems
1. Infrastructure and system architecture area:
Current efforts are focused on developing secure and reliable transaction infrastructure
and pricing regimes. Critical applications being researched and refined include search and
recommendation algorithms that lay the foundation for commercial interactions. The lack
of interoperability in system architecture and application software highlights the need for
net-centric, component-based technologies. The areas for future research initiative focus
on technologies and applications that facilitate real time interactions among users and
computers, including the use of software agents and intermediaries, human-computer
interface design, and system architecture for remote and real-time interactions. In
addition to technology developments, adequate models and measurements must be
developed to be informed about the status, performance and effect of the underlying
system.
2. The interplay between technological infrastructure and commercial environment:
This interplay results in a number of issues that have economic and social ramifications.
For example, the digital online environment has made privacy and intellectual property
rights the most discussed topic in electronic commerce. Nevertheless, current discussions
are carried out in separate circles that focus on technological choices, legalities or other
limited aspects of these issues. It is critical to understand emerging conflicts in a broader,
interrelated solution space and to promote interdisciplinary dialogue and collaboration in
order to provide guidance for design and rule making within the context of online
environment.

There is much uncertainty in the emerging world of electronic commerce. This
uncertainty spans a variety of areas-management, consumer behavior and technology-but
this is good news. History provides numerous examples where market uncertainty has
created potential for shaping new products, creating markets, and building a loyal
customer base. A good case study of uncertainty management is Microsoft, which in the
turbulent days of the early PC software market shaped an entire industry and continues to
reap the benefits. We are on the brink of changes that are projected to rival in impact the
Industrial Revolution of the 18th and 19th Centuries. Much more than making entirely
new knowledge-based products possible, it is clear that electronic commerce will lead to
a fundamental redefinition of the way business is conducted. All participants in the
business community need to wake up to, understand and adapt to electronic commerce.
They need to redefine their business philosophies and approaches so as to position their
organizations to rise with the tide.
3. Vladimir Zwass. Structure and Macro-level impacts of electronic commerce: From
technological infrastructure to electronic marketplaces
25
Electronic commerce (E-commerce) is sharing business information, maintaining
business relationships, and conducting business transactions by means of
telecommunications networks. Traditional E-commerce, conducted with the use of
information technologies centering on electronic data interchange (EDI) over proprietary
value-added networks, is rapidly moving to the Internet. The Internet's World Wide Web
has become the prime driver of contemporary E-commerce. This paper presents a
hierarchical framework of E-commerce, consisting of three meta-levels: infrastructure,
services, and products and structures, which, in turn, consist of seven functional levels.
These levels of E-commerce development, as well as of analysis, range from the widearea telecommunications infrastructure to electronic marketplaces and electronic
4. Frederick J. Riggins and Tridas Mukhopadhyay "Overcoming EDI Adoption and
Implementation Risks," International Journal of Electronic Commerce, Volume 3,
Number 4, Summer 1999,
The emergence of the Internet as a business-to-business communications tool enables a
new wave of adoption of EDI and other interorganizational systems. Initiators of these
trading-partner relationships must develop concrete strategies for managing the adoption
and implementation risks associated with EDI. They may have to subsidize both the
initial adoption and subsequent internal usage of these systems by their trading partners if
they are to maximize their benefits from the technology. EDI can create strategic value in
certain circumstances. To improve internal processes and thus produce operational
benefits, it must improve the information flow between trading partners to the point
where it exceeds the threshold level. Finally, because the operational benefits of EDI are
context-specific, initiators should require their trading partners to develop specific
metrics to measure its effect.
5. Bakos, Y. "A Strategic Analysis of Electronic Marketplaces," MIS Quarterly, Volume
15, No. 3, September 1991, pp. 295-310.
Information systems can serve as intermediaries between the buyers and the sellers in a
vertical market, thus creating an "electronic marketplace". A major impact of these
electronic market systems is that they typically reduce the search costs buyers must pay
to obtain information about the prices and product offerings available in the market.
Economic theory suggests that this reduction in search costs plays a major role in
determining the implications of these systems for market efficiency and competitive
behavior. This article draws on economic models of search and examines how prices,
seller profits, and buyer welfare are affected by reducing search costs in commodity and
differentiated markets. This reduction results in direct efficiency gains from reduced
intermediation costs and in indirect but possibly larger gains in allocational efficiency
from better-informed buyers. Because electronic market systems generally reduce buyers'
search costs, they ultimately increase the efficiency of interorganizational transactions, in
the process affecting the market power of buyers and sellers. The economic
characteristics of electronic markets, in addition to their ability to reduce search costs,
create numerous possibilities for the strategic use of these systems.

Group Support System (GSS)
Introduction and Key Theories
Group Support Systems (GSS) are interactive computer-based environments that support
concerted and coordinated team effort toward completion of joint tasks. GSS allow
groups to work in parallel, typically under anonymous conditions; which allows for high
volume and high quality of deliverable output. GSS can radically change the dynamics of
group interactions by improving communication, by structuring and focusing problem
solving efforts, and by establishing and maintaining an alignment between personal and
group goals. GSS has been used to benefit to many group processes such as
brainstorming, idea generation, SAandD, JAD, and process modeling. As a result, GSS
research is a field of great breadth that involves not only technological aspects, but also
facts such as teaming, facilitation, and group dynamics. One important effect of GSS is
its role of increasing intellectual bandwidth. According to Dr. Jay Nunamaker,
information flows into knowledge management systems (KM) and group support systems
(GSS), and these two systems work synergistically to leverage intellectual bandwidth.
Key Issues and Conflicts
Distributed collaboration is viewed as the major issue. A distributed group support
system has to enable both the facilitator and the participants to perform their tasks. The
facilitator needs a way to monitor the interactions in order to control the collaboration
process. The participants also need a means for communicating with the facilitator as
well as other participants. Another key issue for distributed collaboration is whether the
distributed users can develop the level of awareness and trust required for effective
collaboration. Furthermore, connectivity is a key technological issue for the success of
distributed meetings. Connectivity is especially important for the web-based
collaborations because of the heterogeneity of distributed sites.
Major Research Problems in the Future
The following are key issues and research problems need to be addressed:(this part is
summarized from the article Lessons from a Dozen Years of Group Support Systems
Research: A Discussion of Lab and Field Findings, please see key paper 3 for more
information)
GSS research of distributed groups across different geographical areas (including
distributed facilitation research);
Research of integration of GSS with video conferencing;
Research of integration of GSS with automatic language translation to support
multilingual groups;
Research of GSS transfer and adoption in cultures other than English-speaking countries;
research of GSS to support heterogeneous group; sophisticated GSS software to support
group communication and writing;
Possible uses of GSS in the classroom

The paper identifies the need of GDSS research, and presents a conceptual overview of
GDSS based on an information-exchange perspective of decision-making. Three levels of
systems are described, representing varying degrees of intervention into the decision
30
process. The paper describes the evolution of GDSS. A multidimensional taxonomy of
systems is proposed as an organizing framework for research in the area. The paper also
identifies three critical environmental contingencies to GDSS design: group size, member
proximity, and the task confronting the group. Potential impacts of GDSS on group
processes and outcomes are discussed, and important constructs in need of study are
identified.

This article summarizes research to determine whether or not group size has an effect on
electronic brainstorming by using different group size. The authors found that larger
groups using GSS indeed generated more, high-quality ideas and experienced higher
levels of satisfaction than groups that did not use technology. However, in small groups
(e.g. 2 group members) technology did not act as a catalyst for higher productivity;
primarily because there was no anonymity and not much production blocking (two
primary reasons larger GSS group succeeded).

Information Economics
Key Issues and Conflicts
The interdisciplinary research of information economics draws on principles of
information science, economics, management, political science, public policy,
organizational theory, psychology, ethics, and computer science to propose answers to
the tough new questions confronting the networked society:
When does sharing proprietary information improve a firm’s competitive stance?
Does information technology encourage or impede information equality?
When does it make economic sense to give away information products for free?
Does the Internet require a new regulatory paradigm?
What business models work for information commerce, and how should information
goods be priced [1]?

Masuda Y. “Conceptual Framework Of Information Economics.” IEEE-Transactions-onCommunications, October 1975, 23: (10) 1028-1040.
Information economics is a new system of economics, overriding the classical school of
economics, and at the same time it is a future economics. Three basic concepts of
economics constitute the framework of information economics. The first of them is the
spirit of globalism-the ideas of spaceship, quality of time, and coexistentialism. The
second is information productivity. The development of computer and communication
technologies has made possible mass production of objective-oriented, logical, normative
information. The third is time value-a new view of values. By time value is meant the
value that is created through objective-oriented utilization of free time at the disposal of
human beings. Just as each new theory of economics has a new vision, information
economics has a vision-Global Futualization Society as the society where a large variety
34
of voluntary communities will flourish on a global scale at a time, and the individual will
seek to realize self-acturalization in each community.
Barua, A., Kriebel, C.H., Mukhopadhyay, T. “An Economic Analysis of Strategic
Information Technology Investments.” MIS Quarterly, September 1991, Vol. 15, Iss. 3,
313-332.
The strategic impacts of information technology (IT) investment are studied through the
development of a formal economic model. In particular, the study focuses on IT-related
quality competition in a duopoly, where the services may not be priced initially and
where the benefits may come indirectly. A firm may have to invest in IT, regardless of its
underlying cost structure, as a response to its competitor's investment level. Both firms
prefer sequential over simultaneous investments, even when both have the required
technology. While the IT-inefficient firm has followership incentives, the leadership
incentives for the IT-efficient firm depend on the difference in IT cost structures and on
the degree of substitutability between the services of the 2 firms. For dynamic markets
with new consumers, the negative effect of switching cost on the welfare of existing
consumers is reduced when the IT-efficient firm moves first.
Clemons E., Kleindorfer P. “An Economic-Analysis Of Interorganizational Information
Technology.” Decision Support System, September 1992, 8: (5) 431-446.
This paper first reviews some basic results on the economics of information technology
(IT) and strategy. These results begin by developing a model of interorganizational IT,
focusing on supplier-buyer interactions and the costs and benefits of IT in facilitating
such interactions. The modeling framework incorporates economies of scale and scope,
transactions specific sunk costs of IT development, and related issues of bargaining and
opportunism. Results of the model are applied to the increasingly important topic of
interorganizational information systems, addressing some of the risks of cooperative
ventures that are frequently overlooked in the MIS literature.
Kriebel C., Barua A. and Mukhopadhyay T. “Information Technologies and Business
Value: An Analytical and Empirical Investigation.” Information Systems Research,
March 1995, Vol. 6, Iss. 1, 3-24.
An important management question today is whether the anticipated economic benefits of
information technology (IT) are being realized. In an analysis, this problem is considered
to be measurement related, and a new process-oriented methodology for ex post
measurement is proposed and tested to audit IT impacts on a strategic business unit
(SBU) or profit center's performance. The IT impacts on a given SBU are measured
relative to a group of SBUs in the industry. The methodology involves a 2-stage analysis
of intermediate and higher level output variables that also accounts for industry and
economy wide exogenous variables for tracing and measuring IT contributions. The data
for testing the proposed model were obtained from SBUs in the manufacturing sector.
The results show significant positive impacts of IT at the intermediate level. The study
provides a practical management tool to address the question of why (or why not) certain
IT impacts occur.

Nadiminti R., Mukhopadhyay T., Kriebel C.H. “Risk aversion and the value of
information.” Decision Support System, March 1996,16: (3) 241-254.
Determining the value of information is a fundamental research problem for information
system scientists. Unfortunately, very little research exists that examines the relationship
between risk aversion and the value of information. This is surprising because empirical
studies show that most managers are risk averse rather than risk neutral. Moreover, the
small literature that exists appears to be in conflict. We have developed a framework to
examine the relationship between the value of information and risk aversion. We show
that the method of payment for information must be considered in determining this
relationship. We have used the Arrow-Pratt measure of risk aversion to derive explicit
conditions under which the value of information increases (decreases) with risk aversion.
From our analysis it is clear that earlier work has depicted a limited view of the
relationship between risk aversion and value of information. Our analysis is applicable to
the ex-post evaluation of transaction processing systems and a subset of decision and
expert support systems.
Brynjolfsson, E. and Hitt, L. “Paradox Lost? Firm-level Evidence on the Returns to
Information Systems Spending.” Management Science, April 1996.
The "productivity paradox" of information systems (IS) is that, despite enormous
improvements in the underlying technology, the benefits of IS spending have not been
found in aggregate output statistics. One explanation is that IS spending may lead to
increases in product quality or variety which tend to be overlooked in aggregate output
statistics, even if they increase sales at the firm-level. Furthermore, the restructuring and
cost-cutting that are often necessary to realize the potential benefits of IS have only
recently been undertaken in many firms. Our study uses new firm-level data on several
components of IS spending for 1987-1991. Our results indicate that IS have made a
substantial and statistically significant contribution to firm output.
Hitt, L. and Brynjolfsson, E. “Productivity, Profit and Consumer Welfare: Three
Different Measures of Information Technology's Value.” MIS Quarterly, June 1996.
The business value of information technology (IT) has been debated for a number of
years. While some authors have attributed large productivity improvements and
substantial consumer benefits to IT, others report that IT has not had any bottom line
impact on business profitability. In this paper, we focus on the fact that while
productivity, consumer value and business profitability are related, they are ultimately
separate questions. Accordingly, the empirical results on IT value depend heavily on
which question is being addressed and what data are being used. Applying methods based
on economic theory, we are able to define and examine the relevant hypotheses for each
of these three questions, using recent firm-level data on IT spending by 370 large firms.
Our findings indicate that IT has increased productivity and created substantial value for
consumers. However, these benefits have not resulted in supernormal business
profitability. We conclude that while modeling techniques need to be improved, these
results are consistent with economic theory. Thus, there is no inherent contradiction
between increased productivity, increased consumer value and unchanged business
profitability.

Brynjolfsson, E. “The contribution of information technology to consumer welfare.”
Information Systems Research, September 1996 Vol. 7, Iss. 3 pg. 281, 20 pgs.
Over the past 2 decades, US businesses have invested heavily in information technology
(IT) hardware. Managers often buy IT to enhance customer value in ways that are poorly
measured by conventional output statistics. Further, because of competition, firms may be
unable to capture the full benefits of the value they create. This undermines researchers'
attempts to determine IT value by estimating its contribution to industry productivity or
to company profits and revenues. An alternative approach estimates the consumers'
surplus from IT investments by integrating the area under the demand curve for IT. Using
data from the US Bureau of Economic Analysis, 4 measures of consumers' surplus are
estimated: 1. Marshallian surplus, 2. Exact surplus based on compensated (Hicksian)
demand curves, 3. a nonparametric estimate, and 4. a value based on the theory of index
numbers. All 4 estimates indicate that in the base year of 1987, IT spending generated
approximately $50 billion to $70 billion in net value in the US and increased economic
growth by about 0.3% per year. According to conservative estimates, IT investments
generate approximately 3 times their cost in value for consumers.

Information Retrieval
Key Issues
The techniques used in information retrieval are as follows:
(1) Automatic Text Analysis - concerns how the text of a document is represented inside a
computer.
(2) Automatic Classification - looks at automatic classification methods.
(3) File Structures - from the point of view of someone primarily interested in
information retrieval.
(4) Search Strategies - search strategies when applied to document collections structured
in different ways.
(5) Probabilistic Retrieval - a formal model for enhancing retrieval effectiveness by using
sample information about the frequency of occurrence and co-occurrence of index terms
in the relevant and non-relevant documents.

Automatic Text Structuring and Summarization. Gerard Salton, Amit Singhal, Mandar
Mitra, Chris Buckley: Information Processing and Management 33(2): 193-207 (1997)
In recent years, information retrieval techniques have been used for automatic generation
of semantic hypertext links. This study applies the ideas from the automatic link
generation research to attack another important problem in text processing - automatic
text summarization. An automatic 'general purpose' text summarization tool would be of
immense utility in this age of information overload. Using the techniques used (by most
automatic hypertext link generation link algorithms) for inter-document link generation,
we generate intra-document links between passages of a document. Based on the intradocument linkage pattern of a text, we characterize the structure of the text. We apply the
knowledge of text structure to do automatic text summarization by passage extraction.
We evaluate a set of fifty summaries generated using our techniques by comparing them
to paragraph extracts constructed by humans. The automatic summarization methods
39
perform well, especially in view of the fact that the summaries generated by two humans
for the same article are surprisingly dissimilar.

We report results of a study that involved the creation of knowledge bases of concepts

both based on a semantic network structure, were created automatically using two
statistical algorithms. With the help of four East-bloc computing experts, we evaluated
the two knowledge bases in detail in a concept-association experiment based on recall
and recognition tests. In our experiment, one of the knowledge bases that exhibited the
asymmetric link property out-performed all four experts in recalling relevant concepts in
East-bloc computing. The knowledge base, which contained about 20,000 concepts

This report presents a detailed analysis and review of NLP evaluation, in principle and in
practice. Part 1 examines evaluation concepts and establishes a framework for NLP
system evaluation. This makes use of experience in the related area of information
retrieval and the analysis also refers to evaluation in speech processing. Part 2 surveys
significant evaluation work done so far, for instance in machine translation, and discusses
the particular problems of generic system evaluation. The conclusion is that evaluation
strategies and techniques for NLP need much more development, in particular to take
proper account of the influence of system tasks and settings. Part 3 develops a general
approach to NLP evaluation, aimed at methodologically sound strategies for test and
evaluation.

Knowledge Management
Introduction
As the attention of human beings becomes the most critical resource in the information
age, the need to manage vast amount and different levels of knowledge (see Figure 1)
becomes apparent. Knowledge management is a discipline that promotes an integrated
approach to identifying, capturing, retrieving, sharing and evaluating an enterprise’s
information assets. These information assets may include databases, documents, policies
and procedures as well as the un-captured, tacit expertise and experience resident in
individual workers.

Categories of Knowledge Management Research
Knowledge management investigates areas such as visualization, categorization,
representation of data, information, knowledge and wisdom to enable transfer and sharing
of knowledge and information to other groups and people. This discipline is essentially
divided into technical aspect and behavioral aspect. The technical aspect is composed of
four categories, namely, information retrieval, digital library, collaboration, and data
mining. The behavioral aspect is composed of four categories, namely, consulting in
knowledge management, best practices, organizational memory, knowledge networking /
integration.
41
Key Theories and Methodologies
Knowledge Management is a cross-disciplinary research area. The key theories and
methodologies in the behavioral side include cognitive psychology theories, human
communication theories, and group theories. The key theories and methodologies in the
technical side include statistical theories, self-organizing map, mathematical
representation schemes, automatic text processing methods, workflow technologies,
agent theory, ontology, meta-data and various visualization techniques.
Key Issues
The technical aspect of knowledge management is concerned with how to capture
semantic knowledge and meanings, how to visualize knowledge, how to integrate
knowledge, and how to deal with multilingual knowledge. The behavioral aspect of
knowledge management is concerned with what are the best practices, organizational
change and reward, case studies in knowledge management, and social and human aspect
of knowledge management. The technical and behavioral aspects drive each other to
enhance the field of knowledge management.
Future Research Trends
Relevance -- having all the available, relevant knowledge available for decision-making.
Dynamism -- knowledge about the state of multiple processes operating in parallel and
affecting each other in a coordinated way.
Community -- a collective environment that actively supports sharing through automatic
capture in sharable form and explicit policies and open cultures that promote sharing.

This book deals with the whole area of automatic text processing – that is, the handling of
texts using automatic equipment. The aim is not to teach laymen or humanists how to
program computers to manipulate text, nor to teach scientists language-processing skills.
Instead, this book examines the area of text processing as a whole, describing various
text-processing methodologies and identifying those tasks now undertaken routinely,
while also discussing more experimental procedures not yet ready for operation. This
book is divided into four parts: the first part covers the computer environment and
automated office situation, in which text processing is of particular interest. The second
part covers the main word processing areas, which treat texts on the level of individual
words. The third part covers text-retrieval systems whose operations are normally based
on text units larger than single, individual word forms. The fourth part covers the main
language-analysis and language-processing topics in which text meaning and text
understanding are of principle concern: syntactic and semantic language-analysis
methods that determine language structure and text content, and knowledge-based text
processing.

Intelligent Systems and their applications 13(3), May-June 1998, pp.30 –33.
Organizations use knowledge management for a number of reasons, including
environmental pressures, technological advancements, and the ability to create valuable
information. Classic knowledge management thinking assumes that a firm gathers all its
important knowledge in a single place, and employees use it to make good decisions that
will benefit the organization. But this classical thinking is only partially right. The full
range of knowledge management converting and connecting capabilities should include
not only connecting knowledge and people, but also link knowledge to other knowledge
or push knowledge to other knowledge or push knowledge out to employees.

Operation Research
Introduction
Operation Research (OR) looks at an organization’s operations - the functions it exists to
perform. The objective of Operational Researchers is to work with clients to find
practical and pragmatic solutions to operational or strategic problems, often working
within tight timing constraints.
Organizations may seek a very wide range of operational improvements - for example,
greater efficiency, better customer service, higher quality or lower cost. Whatever the
business engineering aim, OR can offer the flexibility and adaptability to provide
objective help.
Most of the problems OR tackles are messy and complex, often entailing considerable
uncertainty. OR can use advanced quantitative methods, modelling, problem structuring,
simulation and other analytical techniques to examine assumptions, facilitate an in -depth
understanding and decide on practical action.
The future issues will focus on decision analysis, vehicle routing, and effectiveness of
mandatory minimum sentencing and information technology. MIS researcher can look at
the opportunities of facilitating OR with information system, making the switch from
academia to the "real world"

Social/Ethical/Psychological Issues
Introduction
Social, psychological, and ethical issues are important factors to consider in regards to
information systems research because of the way they directly affect its users. Social
issues address the impacts of the computer technologies that are currently available on
organizations, individuals, and communities. Ethical issues involve privacy concerns,
moral dilemmas, and sensitive information. The psychological issues within technology
research deal with the cognitive and emotional states of people utilizing it. From these
areas of research, self-regulation, laws governing computer technology, sociological and
psychological well beings of people stems from these areas of research.
Most Important Theories
Some important theories, hypothesis, and models to come from this area of research are
the Media Richness Theory, Social Presence Theory, SIDE theory, Computers as Social
Actors, and Internet Addiction Theory.
Key Issues, Conflicts, and Major Research Problems
Amongst this body of literature, there are three major arguments that researchers uphold.
The first is the ethical use of using subjects over the Internet. When looking at the social
and psychological impacts of technology, a vast majority of research has been pertaining
to areas involving the Internet (e.g., e-commerce, distance learning, privacy issues).
Therefore, researchers raise the questions if it is considered ethical to monitor
transactional behaviors of consumers and/or read through e-mail messages and postings
found in chat rooms without the users consent. Another research problem is the ability to
be able to study technology that is always in flux.

Kraut, Kiesler, Mukhopadhyay, Scherlis, and Patterson. (1998). Social impact of the
Internet: What does it mean? Communications of the ACM (41), 12.
According to prior research involving studies regarding the HomeNet project, results
were found that people using the Internet incurred declines in social and psychological
well-being. Depression increased, communication between friends and family decreased,
and people overall felt lonelier even though the purpose for using the Internet was to
increase their interpersonal communication. Other outcomes of the study showed that
there is a difference between people who have positive versus negative attitudes about the
Internet. People with positive attitudes are not as concerned with their privacy, perceive
shopping by mail as beneficial, and have coping strategies for dealing with unwanted
mail. The authors give future research suggestions including focusing on characteristics
such as the sensitivity of the information, its source, its perceived relevance to the
original transaction, and whether disclosure reflects informed consent or results in a
potentially harmful outcome to the individual. This has implications for MIS research
involving e-commerce. Due to findings, MIS e-commerce research needs to take into
consideration people's attitudes about the Internet so that they can target ways in which to
assure people of their privacy and also encourage on-line shopping.

affordances visible, participate in natural mappings, taking advantage of physical
analogies and cultural understandings, and integrating user feedback. His discussion
revolves around taking a user-based center when designing anything from hardware to
software to tools. At times, MIS researchers focus on task and problem solving with little
regards to the user. The field of MIS research can benefit by reading this chapter as it
allows for awareness of user importance in design.

understanding of how people are using new technologies and the social norms that are
already established on-line. They can in turn use this found knowledge by learning how
53
to redesign systems that are already in place to better serve its users. They can also
research into how people are using the systems already and project and propose future
research and better systems.

Supply Chain Management
Most Important Theories
To compete successfully in the global market, companies need to manage the
effectiveness and efficiency of the operations that manufacture and distribute their
products or services to their customers. Supply chain management deals with the
management of materials, information and financial flows in a network consisting of
suppliers, manufacturers, distributors, retailers, and customers. Many industries have
found it challenging to manage these flows efficiently and effectively.
There are three types of flows in a supply chain that require careful planning and
coordination. Material flows involve both physical product flows from suppliers to
customers through the chain as well as the reverse flows via product returns, servicing,
recycling, and disposal. Information flows involve order transmission and delivery status.
Financial flows involve credit terms, payment schedules, and consignment and title
ownership arrangements. These flows cut across companies and sometimes ownership
arrangements. These flows cut across companies and sometimes even industries [1].
Key Issues and Conflicts
The research of Supply Chain Management processes focuses on the coordination and
integration of the flows in a supply chain consisting of multiple sites and organizations
with multiple independent decision makers. The types of research in Supply Chain
Management can be:
Theoretical work motivated by real life problems and situations
Applications based on real cases
Conceptual work that provides a framework to analyze problems in industry
Empirical studies based on real data
Surveys of existing literature and industrial practice [1]
Key research issues and topics include: product and process designs for supply chain
management; structuring supply chains for mass customization; third party logistics;
outsourcing and contract manufacturing; supplier contracting; incentive and performance
measures; global supply chain management; quick response and cycle time reduction;
multi-product and multi-location production and inventory coordination; consolidation,
warehousing, scheduling and coordination of transportation and production flows; and
industry-wide supply chain integration.

bullwhip effect.” Management Science, April 1997, Vol. 43, Iss. 4; pg. 546, 13 pgs.
A series of companies in a supply chain is considered, each of who orders from its
immediate upstream member. In this setting, inbound orders from a downstream member
serve as a valuable informational input to upstream production and inventory decisions. It
is claimed that the information transferred in the form of orders tends to be distorted and
can misguide upstream members in their inventory and production decisions. In
particular, the variance of orders may be larger than that of sales, and the distortion tends
to increase as one moves upstream - a phenomenon termed the bullwhip effect. Four
sources of the bullwhip effect are analyzed: demand signal processing, rationing game,
order batching, and price variations. Actions that can be taken to mitigate the detrimental
impact of this distortion are also discussed.

Cachon G.P., Lariviere M.A. “Capacity choice and allocation: Strategic behavior and
supply chain performance.” Management Science, August 1999, 45, 8, 1091-1109.
A simple supply chain in which a single supplier sells to several downstream retailers is
considered. The supplier has limited capacity, and retailers are privately informed of their
optimal stocking levels. If retailer orders exceed available capacity, the supplier allocates
capacity using a publicly known allocation mechanism, a mapping from retailer orders to
capacity assignments. It is shown that a broad class of mechanisms is prone to
manipulation; retailers will order more than they need to gain a more favorable
allocation. Another class of mechanisms induces the retailers to order exactly their needs,
thereby revealing their private information. However, there does not exist a truthinducing mechanism that maximizes total retailer profits. The supplier's capacity choice
is also considered. It is shown that a manipulable mechanism may lead the supplier to
choose a higher level of capacity than one would under a truth-inducing mechanism.
Nevertheless, one's choice will appear excessively restrictive relative to the prevailing
distribution of orders.
Cachon, G.P. “Managing supply chain demand variability with scheduled ordering
policies.” Management Science, June 1999, Vol. 45, 6, 843-857.
Supply chain demand variability is studied in a model with one supplier and N retailers
that face stochastic demand. Retailers implement scheduled ordering policies: Orders
occur at fixed intervals and are equal to some multiple of a fixed batch size. A method is
presented that exactly evaluates costs. Previous research demonstrates that the supplier's
demand variance declines as the retailers' order intervals are balanced, i.e., the same
number of retailers order each period. It is shown that the supplier's demand variance will
(generally) decline as the retailers' order interval is lengthened or as their batch size is
increased. Lower supplier demand variance can certainly lead to lower inventory at the
supplier. It is found that reducing supplier demand variance with scheduled ordering
policies can also lower total supply chain costs.
Chen F. “Decentralized supply chains subject to information delays.” Management
Science, August 1999, Vol. 45, Iss. 8, 1076-1091.
A supply chain whose members are divisions of the same firm are considered. The
divisions are managed by different individuals with only local inventory information.
Both the material and information flows in the supply chain are subject to delays. Under
the assumption that the division managers share a common goal to optimize the overall
performance of the supply chain, the optimal decision rules for the divisions are
characterized. The team solution reveals the role of information leadtimes in determining
the optimal replenishment strategies. It is shown that the owner of the firm can manage
the divisions as cost centers without compromising the systemwide performance. This is
achieved by using an incentive-compatible measurement scheme based on accounting
inventory levels. The impact of irrational behavior on supply chain performance is
investigated. It is important for the upstream members of the supply chain to have access
to accurate customer demand information.
Gavirneni S., Kapuscinski R., and Tayur S. "Value of information of capacitated supply
chains.” Management Science, January 1999, Vol. 45, Iss. 1; pg. 16, 9 pgs.
57
Information flow is incorporated between a supplier and a retailer in a two-echelon model
that captures the capacitated setting of a typical supply chain. Three situations are
considered: 1. A traditional model where there is no information to the supplier prior to a
demand to him except for past data, 2. The supplier knows the (s, S) policy used by the
retailer as well as the end-item demand distribution, and 3. The supplier has full
information about the state of the retailer. Order up-to policies continue to be optimal for
models with information flow for the finite horizon, the infinite horizon discounted and
the infinite horizon average cost cases. Study of these three models enables one to
understand the relationships between capacity, inventory, and information at the supplier
level, as well as how they are affected by the retailer's (S - s) values and end-item demand
distribution. The savings at the supplier due to information flow are estimated and when
information is most beneficial is studied.

Systems Analysis and Design
Key Issues
1.Software has become an integral part of world's economy. Software development and
deployment remain labor-intensive and intellectually demanding, requiring the best from
developers who must play a number of roles. There are still problems in the process of
making complex software.
2. Shortening cycle time for software projects with more efficiency.
3.Techniques for reuse of software.
4.New techniques for analysis and design- like UML. Further growth into the object
oriented approach.

on his own projects. He created the Fagan Defect-Free Process, incorporating
Formal Process Definition, and reinforcing the Continuous Process
Improvement aspect of the Inspection Process. Using the inspection method, he
was also able to use its metrics to monitor projects and keep them on track. The
methodology developed by Michael Fagan is credited with dramatically reducing the
number of defects in software and hardware products, increasing the feature content per
release, shortening cycle time, increasing customer satisfaction, improving development
processes, accelerating SEI/CMM maturity in organizations, and significantly reducing
costs! He was the first software senior technical staff member in IBM's T.J. Watson
Research Laboratory; a member of the Corporate Technology Staff; and, one of the
founder members of the IBM Quality Institute. After creating the Inspection Process in
1972, he continued refining the methodology, incorporating Formal Process Definition,
and reinforcing the Continuous Process Improvement aspect of the Fagan Inspection
Process. Since 1989, when he formed Michael Fagan Associates, he has continued to
refine the methodology and has also found ways to help facilitate its very rapid
implementation in more than 60 organizations. From 1983 to 1985, Michael Fagan was a

author goes on to say that "a more fundamental symptom of cycle-time problems is
rework. The more you do things over, the more [work in process] you'll have, which
means you add cost and introduce delays.

Telecommunication
Key Theories and Issues
Today's computer communication networks are based on a technology called packet
switching. Data to be communicated is broken into small chunks that are labeled to show
where they come from and where they are to go. Packets are forwarded from one
computer to another until they arrive at their destination. If any are lost, they are re-sent
by the originator. The recipient acknowledges receipt of packets to eliminate unnecessary
re-transmissions.
ARPANET, a pioneering work in the networking field, was initiated in 1969. Since then
numerous networking research was progressed to solve the problem of linking different
kinds of packet networks together without requiring the users or their computers to know
much about how packets moved from one network to another. A new set of computer
communication protocols, TCP/IP (Transmission Control Protocol and Internet Protocol),
that would allow multiple packet networks to be interconnected in a flexible and dynamic
way were developed to speed up the invention of what was later known as Internet. By
the mid-1980s there was sufficient interest in the use of Internet for business
implementation. An experimental electronic mail relay was built and put into operation in
1989 and its commercial use has exploded. The Internet has been experiencing
exponential growth in the number of networks, number of hosts, and volume of traffic.
One of the major forces behind the exponential growth of the Internet is a variety of new
capabilities in the network -- particularly directory, indexing, and searching services that
help users discover information in the vast sea of the Internet. Many of these services
have started as university research efforts and evolved into businesses. The World Wide
Web was first used in experimental form in 1989, and researchers developed a graphical
browser for the Web which, combined with hypertext, started a new telecommunication
era.
Future Work
It is risky to predict the future of something as dynamic as the Internet. It seems safe to
state that there will be a continuing explosion of new services. There is every reason to
believe that the Internet will transform education, business, government, and personal
activities in ways we cannot fully fathom. The main challenge would come from how to
predict the future networking trend and catch up with the rapid technical evolution while
there is almost no clue to predict for the future.

Key Articles
“Compatibility or Chaos in Communications”, Sanders, Ray W.; Cerf, Vinton G.;
Datamation, Barrington; Mar. 1976; Vol. 22, Issue 3.
A conflict is developing in data-communications in transmitting data between the
manufacture’s equipment and other brands. The users are pushing to erase as many major
incompatibilities as possible. Network Standardization would benefit both sides by giving
users more choice of equipment while opening new markets that would be economically
feasible due to resource sharing. Users must have a greater comprehension of networks.
An explanation of networks, access methods, layers of network access protocols, physical
link, and packet-level protocol is presented. Also discussed are the protocols on top of
protocols – link control header, packet header, information field, and control trailer,
graph and diagram.

“Information Processing Technology for Emergency Management”, Kahn, Robert E.
Information Society, New York; 1985.
Several information-processing technologies are capable of augmenting human
performance in handling a range of emergency situations. Technological areas that are
particularly important to emergency management are: communications, computers,
machine intelligence, and security. Both conventional and emerging technologies are
important in the area of communication networks. Some of the systems that have proved
useful in enhancing information collection, transmission, and selective processing are:
packet radio networks, satellite network technology, expert planning systems, Interneting,
and machine intelligence. Packet radio and multiple satellite technology, both based on
packet-switching, can make a considerable difference, and computer-based Internetwork
-systems will initially be most useful for communicating messages electronically. To be
effective, information technology must be integrated into daily patterns to make its use
comfortable and familiar.
“The Heart of Connection: Hypermedia Unified by Transclusion”, Nelson, Ted;
Association for Computing Machinery, New York; Aug 1995; Vol. 38, Issue 8.
The development of a system for massive parallel creative work and study is discussed.
The system is intended to be a technical, legal, and commercial basis for a worldwide
populist and participatory electronic literature of freely weaving screen transmedia republishable and quotable without restrictions - to the betterment of human
understanding and freedom of expression and access. The central idea is the concept of
transclusion, or reuse with original context available, through embedded shared
instancing (rather than duplicate bytes). Thus the user may intercompare contexts of what
is re-used, both for personal work and publication. The elements of transclusion are
discussed.
“Intradomain Qos Routing In IP Networks, A Feasibility And Cost/Benefit Analysis”,
Guerin, Roch, IEEE Network, 1999.
Constraint-based routing gradually becomes an essential enabling mechanism for a
variety of emerging network services. In this work the workers build on previous results
on the cost of QoS routing and investigate the performance/cost trade-offs involved in the
operation of a representative QoS routing architecture, elaborate on the constituents of
this cost, and identify the main methods for containing the cost that QoS routing incurs
on routers. The results show that the cost of QoS routing is not excessive and that there
exist operational configurations, which can achieve reasonable performance gains with
only a minimal increase in processing cost when compared to conventional best-effort
routing.
“An Analysis of TCP Processing Overhead”, David Clark; V. Jacobson, J. Romkey; H.
Salwen, IEEE Communications Magazine, June 1989, Vol. 27, No. 6.
The transport layer of the protocol suite, especially in connectionless protocols, has
considerable functionality and is typically executed in software by the host processor at
the end points of the network. It is thus considered a likely source of processing
overhead. However, a preliminary examination has suggested to the authors that other
aspects of networking may be a more serious source of overhead. To test this proposition,
66
a detailed study was made of the Transmission Control Protocol (TCP), the transport
protocol from the Internet protocol suite. In this set of protocols, the functions of
detecting and recovering lost or corrupted packets, flow control, and multiplexing are
performed at the transport level. The results of that study are presented. It is concluded
that TCP is in fact not the source of the overhead often observed in packet processing,
and that it could support very high speeds if properly implemented.
“Controls for Interorganization Networks”, Estrin, Deborah; IEEE Transactions On
Software Engineering, New York; Feb 1987; Vol. SE13, Issue 2.
Interorganization computer networks support person-to-person communication via
various methods. Because of most firms' desire for limited access of resources to
outsiders, interorganization networks (ION) have unique usage-control requirements. A
conceptual model for implementing usage control in IONs is described. Usage control
requirements in networks that cross organization boundaries are discussed. The analysis
indicates that category sets and nondiscretionary control mechanisms can be employed to
isolate strictly internal facilities from ION facilities and distinct IONs from one another.
Attention is then focused on the problem of authentification in IONs -- an essential
component of the proposed control mechanisms.

Workflow
Introduction
1. Definition - Workflow
The computerized facilitation or automation of a business process, in whole or part.
Workflow is often associated with Business Process Re-engineering, which is concerned
with the assessment, analysis, modeling, definition and subsequent operational
implementation of the core business processes of an organization (or other business
entity).
2. Definition - Workflow Management System
A system that completely defines, manages and executes “workflows” through the
execution of software whose order of execution is driven by a computer representation of
the workflow logic.
The Evolution of Workflow
The evolution of workflow as a technology has thus encompassed a number of different
product areas.
Image Processing
Document Management
Electronic Mail and Directories
Groupware Applications
Transaction-based Applications
Project Support Software
BPR and Structured System Design Tools

Key Papers
Dimitrios, Mark Hornick and Amith Sheith An Overview of Workflow Management:
From Process Modeling to Workflow Automation Infrastructure, Distributed and Parallel
Database, 3, 119-153 (1995)
Today's business enterprises must deal with global competition, reduce the cost of doing
business, and rapidly develop new services and products. To address these requirements
enterprises must constantly reconsider and optimize the way they do business and change
their information systems and applications to support evolving business processes.
Workflow technology facilitates these by providing methodologies and software to
support (i) business process modeling to capture business processes as workflow
specifications, (ii) business process reengineering to optimize specified processes, and
(iii) workflow automation to generate workflow implementations from workflow
specifications. This paper provides a high-level overview of the current workflow
management methodologies and software products. In addition, it discusses the
infrastructure technologies that can address the limitations of current commercial
workflow technology and extend the scope and mission of workflow management
systems to support increased workflow automation in complex real-world environments
involving heterogeneous, autonomous, and distributed information systems. In particular,
it discusses how distributed object management and customized transaction management
can support further advances in the commercial state of the art in this area.
2. Akhil Kumar; J Leon Zhao; Dynamic routing and operational controls in workflow
management systems; Management Science, Providence; Feb 1999; 45, 2; 253-273.
Businesses around the world are paying more attention to process management and
process automation to improve organizational efficiency and effectiveness. A general
framework for implementing dynamic routing and operational control mechanisms in
workflow management systems (WMS) is described. The framework consists of three
techniques: workflow control tables, sequence constraints, and event-based workflow
management rules. This approach offers several unique features that are missing in
commercial workflow management systems: 1. It provides more flexibility in process
modeling and control. 2. It permits rework on an ad hoc basis. 3. It handles exceptions to
routing and operational controls. 4. It exploits parallelism to increase system throughput
and response time. Finally, the workflow management techniques are applied to the case
of consumer loan management and compared with other approaches based on static
routing.
3. W.M.P. van der Aalst, The Application of Petri Nets to Workflow Management ,
Department of Mathematics and Computer Science reports, Eindhoven University of
Technology.
Workflow management promises a new solution to an age-old problem: controlling,
monitoring, optimizing and supporting business processes. What is new about workflow
management is the explicit representation of the business process logic which allows for
computerized support. This paper discusses the use of Petri nets in the context of
workflow management. Petri nets are an established tool for modeling and analyzing
processes. On the one hand, Petri nets can be used as a design language for the
70
specification of complex workflows. On the other hand, Petri net theory provides for
powerful analysis techniques which can be used to verify the correctness of workflow
procedures. This paper introduces workflow management as an application domain for
Petri nets, presents state-of-the-art results with respect to the verification of workflows,
and highlights some Petri-net-based workflow tools.
4. Christoph Bussler, Stefan Jablonski; Implementing Agent Coordination for Workflow
Management Systems Using Active Database Systems. RIDE-ADS 1994: 53-59
One crucial function of a workflow management system (WFMS) is to assign tasks to
users who are eligible to carry them out. Except in simple workflow scenarios, roles such
as secretary and manager are not a sufficient basis for determining eligibility.
Additionally, WFMSs are deployed not only in group settings by small companies but
also worldwide by large enterprises. Since local laws and business policies have to be
followed, task assignment policies for the same task generally differ from country to
country and, therefore, must be specified locally. The Policy Resolution Architecture
(PRA) model provides more generality and expressiveness than role models do and at the
same time supports the independent specification of task assignment policies in different
parts of an enterprise. PRA can be used to model arbitrary organization structures and to
define realistic task assignment (eligibility) rules by means of precisely defined
organizational policies. Thus, PRA provides real-world organizations with a precise,
simple means of expressing their complex task assignment policies.
