Information Technology Management Perspectives, Focus, and Change in the 21st century Paradigm shift The models for managing IT strategy, the IT function, and IT projects are changing in the twenty-first century. The past is inadequate for fitting the environmental turbulence . Environmental scanning External IT fundamental changes High computing power Network-oriented processing Wireless-oriented accessing Organizational behavior/structure adaptation for searching fitness The computer-literate & network-centric knowledge worker Five eras of IT evolution First era: pioneers, penetration, and chaos (1954-1963) (the proud age of transistor) Second era: gaining control-centralization and a technical monopoly (1964-1976) (after the IC breakthrough against the tyranny of numbers) Third era: letting loose-distribution and decentralization (1977-1984) (the dominant age of IBM) Fourth era: distribution-a free market with issues of architecture and management (1985-1996) (the frogleap of Wintel ) Fifth era: the worldwide web and anytime/anyplace computing (1997 into the 21st century) (the Internet era) First era The first commercial computer was installed in a General Electric Plant in 1954 Univac I machine was once a leader in the market place. Scientific applications were dominant in the age of Cold War. FORTRAN and COBOL did not emerge as the popular programming languages until the late of this era. First era (Cont.) Computing: isolated machines Applications: Scientific and engineering; machine-specific programs Management: in-house training of technical staff Organization: unplanned, chaotic Key issues: few concerns; computing is a mystery, scattered and hidden from top management view Second era Technological advances: IBM system 360 series—a modularized design ignited the dramatic growth of computer industry and brought consolidation of organizational computing resources direct-access storage devices (DASD), telecommunication, Multiple access computing Beyond the function of accounting: included several efficiency-enhanced transaction processing systems, e.g., inventory control, banking, airline, taxing, healthcare, etc. Second era (Cont.) Computing: Distributed access to mainframes; compatible product lines Applications: accounting, inventory, and business transactions Management: standardized programming languages, early database technology Organization: consolidation of control within the data processing function Key issues: rising cost, unmet user expectations Third era Minicomputer emerges: DEC VAX series, Wang, and equipments of Japan’s electronic firms Increasing demands of IT processing services Focusing on the effective & efficient IS development methods—SDLC & User involvement Externally-developed software packages were available (the spill-over effect of IBM) IT organization and management in a advisory, service-oriented role IT as a source of competitive advantage in the marketplace (focus on efficiency) Third era (Cont.) Computing: midrange computers, easy-to-use interfaces Applications: commercial and user-developed applications complement internal systems development efforts Management: systems development life cycle procedures; distributed IT development Organization: greater business unit control of IT Key issues: coordination of centralized and businessunit IT efforts Fourth era PC innovation and widely uses of software packages The Wintel standard move the computing infrastructure forward Network technologies connected the legacy systems and the current PCs A harmonious IS settings with flexibility Emerging inter-organizational data exchange applications: ERP, SCM, etc. Fourth era (Cont.) Computing: personal computers, LANs, Internet and extranets Applications: user-friendly applications, desktop systems followed by groupware and workflow system Management: user-driven systems management; everyone is an IT manager; project control techniques Organization: federated or free market approach to IT, including centralized, decentralized, and outsourced IT operations Key issues: incompatible systems, integration difficulties, Y2K Fifth era This is a dotcom era contributed greatly after Netscape IPO The business model of click-and-mortar integration N-generation & M-generation workers The new economics of information Fifth era (Cont.) Computing: PDA, mobile technology, Internet as primary platform Applications: electronic commerce systems Management: professionalism and team skills are paramount; flexibility is added to project control Organization: downsizing of corporate IT, integration of business and IT operations Key issues: embracing both old and new models of IT management IT advantage transformation From transaction processing to business relationship exploration From IS scalability to IS mobility & agility From the alignment with business strategy to the reach beyond the traditional business scopes IT management transformation Centralization & decentralization A total business approach around IT In-sourcing & outsourcing (the make-orbuy decision) Top management engagement—active participation Project management transformation Project management team may change along with shifts in business needs Rapid everything and virtual many things (the object-oriented programming project) Trust & innovation rather than control Action and risk assessment more than system analysis (standard betting & selection) Up-to-the-minute clarity of information Extending readings Malone, Thomas W,.
