Managerial Decision Making Chapter 7 Copyright Atomic Dog Publishing, 2003 Management Decision Making Management decision making is a complex mix of knowledge, experience, creative thinking, and risk taking. It is often a rapid-fire, fragmented process More and more companies are pushing critical decision making down to the level of the organization most affected by the decision A decision can be defined as a conscious choice among alternatives followed by action to implement the decision Decision-making process is a series of steps that is followed, either consciously or unconsciously, to make a choice and undertake action 2/42 Copyright Atomic Dog Publishing, 2003 Management Decision Making (cont.) Managers must learn how to deal with a decisionmaking environment that emphasizes communicating, working with others, and working with incomplete information Decisions are often based on impressions, estimates, and personal experience Management researchers have developed a set of useful concepts to understand the phenomenon Individual decision making differs from group decision making 3/42 Copyright Atomic Dog Publishing, 2003 Types of Managerial Decisions Copyright Atomic Dog Publishing, 2003 Types of Managerial Decisions Programmed and Non-Programmed Decisions Proactive and Reactive Decisions Intuitive and Systematic Decisions 5/42 Copyright Atomic Dog Publishing, 2003 Programmed and Non-Programmed Decisions Programmed Decisions One that would be made if a particular situation occurs and a routine procedure or policy has been established to handle it Repetitive and routine A large number in daily operations Although they should be made with care and concern about effectiveness, they should be made efficiently without needlessly tying up organizational resources 6/42 Copyright Atomic Dog Publishing, 2003 Programmed and Non-Programmed Decisions (cont.) Non-Programmed Decisions No pre-existing structure or decisionmaking procedure in place Have significant implications for the future of the organization and must be made only after careful analysis 7/42 Copyright Atomic Dog Publishing, 2003 Proactive and Reactive Decisions Proactive Decision Made in anticipation of an external change or other conditions Can prevent many common problems Reactive Decision Made in response to changes that have already occurred 8/42 Copyright Atomic Dog Publishing, 2003 Intuitive and Systematic Decisions Intuitive Decision Making Use of estimates, guesses, or hunches to decide among alternative courses of action “Voice of experience” that speaks to managers when faced with a decision situation Don’t rely on intuition alone; supplement intuition with systematic information gathering and analysis Systematic Decision Making Organized, exacting, data-driven process Requires a clear set of objectives, a relevant information base, and a sharing of ideas among key managers and other employees 9/42 Copyright Atomic Dog Publishing, 2003 The Decision-Making Process Copyright Atomic Dog Publishing, 2003 The Decision-Making Process Clarify the problem or opportunity Develop alternative courses of action Evaluate and select a course of action Implement the decision Monitor its effectiveness 11/42 Copyright Atomic Dog Publishing, 2003 Step 1: Clarify the Problem or Opportunity Problems are defined as the realization that a discrepancy exists between a desired state and current reality Several common biases or mistakes managers make when identifying and clarifying a problem: Perceptual inaccuracies Defining problems in terms of solutions Identifying symptoms as problems Consider an issue from a variety of perspectives Consult various perspectives before making decisions 12/42 Copyright Atomic Dog Publishing, 2003 Step 2: Develop Alternative Courses of Action Examine the organization’s internal and external environments for information and ideas that may lead to creative solutions to a problem A popular approach to this is known as benchmarking (identify and study firms who are leaders in a given area of business) Managers should encourage creativity and innovation among employees Encourage a diversity of approaches to problem solving can lead to better solutions and courses of action 13/42 Copyright Atomic Dog Publishing, 2003 Step 3: Evaluate Alternatives and Select a Course of Action Select the alternatives that will produce the most favorable outcomes and the least unfavorable outcomes Two cautions should be kept in mind Keep this step distinct from the previous step—especially in a group context Be wary of solutions that are evaluated as being “perfect” Rather than being an optimizer, the decision maker is said to be a “satisficer” —a person who accepts a reasonable alternative course of action that isn’t necessarily the optimum course of action 14/42 Copyright Atomic Dog Publishing, 2003 Step 4: Implement the Selected Alternative Course of Action A decision is an abstraction if it isn’t implemented Actions must be implemented effectively if it is to achieve an objective Implementing decisions involves delegating responsibilities to people Here are six steps to effective delegation: Define the task clearly Give guidelines to begin to follow Give authority to accomplish the task Monitor the tasks, but don’t hover Give feedback along the way Reward and recognize effort as well as results 15/42 Copyright Atomic Dog Publishing, 2003 Step 5: Control and Assess the Consequences of the Action Periodic assessment of the results of the chosen course of action If actual results aren’t meeting planned results, changes must be made Two types of feedback that managers use to gather the necessary information: Formative Summative 16/42 Copyright Atomic Dog Publishing, 2003 Influences on Individual Decision Making Copyright Atomic Dog Publishing, 2003 Influences on Individual Decision Making Importance of the decision Time pressures Manager’s values Manager’s propensity for risk 18/42 Copyright Atomic Dog Publishing, 2003 The Importance of the Decision Numerous yardsticks for measuring the importance of a decision exist, including the amount of resources involved, the number of people influenced by the decision, and the time required to make the decision Managers must allot more time and attention to significant problems 19/42 Copyright Atomic Dog Publishing, 2003 Time Pressures Managers must make the most of their decisions in others’ time frames When time pressures are significant, managers may be unable to gather enough information Time management is a priority Managers who effectively manage their time feel less stress and tend to make better decisions than their stress-filled counterparts 20/42 Copyright Atomic Dog Publishing, 2003 The Manager’s Values An individual’s values become guidelines when s/he confronts a choice Values are one of the most important influences on human behavior Values are the likes, dislikes, shoulds, oughts, judgments, and prejudices that determine how the world is viewed Value-based decision making is methodical and ensures that organizational values enter into all major decisions Although people don’t think consciously about their values and rarely arrange them in any kind of order, managers should be very aware of their values Serious conflicts can occur among values 21/42 Copyright Atomic Dog Publishing, 2003 The Manager’s Propensity for Risk People vary greatly in their propensity to take risks The issue for managers is not whether to take risks, but how to take reasonable risks 22/42 Copyright Atomic Dog Publishing, 2003 Group Decision Making Copyright Atomic Dog Publishing, 2003 Group Decision Making A great deal of decision making is achieved through committees, teams, task forces, “virtual teams,” etc. Decisions made on non-programmed problems being made by one individual on a regular basis are unusual Use of the collective approach to a decisionmaking process is increasing Many managers spend as much as 80% of their working time in committee meetings 24/42 Copyright Atomic Dog Publishing, 2003 Individual vs. Group Decision Making Groups usually take more time to reach a decision Consensus decisions with five or more participants are superior to individual decision making, majority vote, and leader decisions Problems with group decision making: Pressure to conform Influence of a dominant personality Status incongruity Attempt of certain participants to influence others 25/42 Copyright Atomic Dog Publishing, 2003 Individual vs. Group Decision Making (cont.) Non-programmed decisions appear to be better suited to group decision making As we move from “individual” to “consensus,” the quality of the decision improves For a complex problem requiring pooled knowledge, the quality of the decision is likely to be higher as the group moves toward achieving consensus 26/42 Copyright Atomic Dog Publishing, 2003 Creativity in Group Decision Making If groups are better suited to non-programmed decisions than individuals, then it is important that an atmosphere fostering group creativity be created 27/42 Copyright Atomic Dog Publishing, 2003 Techniques for Stimulating Creativity Brainstorming The Delphi Technique The Nominal Group Technique 28/42 Copyright Atomic Dog Publishing, 2003 Brainstorming Brainstorming promotes the generation of ideas while at the same time avoiding the inhibitions many people feel in group settings The basic rules are: No idea is too ridiculous Each idea presented belongs to the group, not to the person stating it No idea can be criticized 29/42 Copyright Atomic Dog Publishing, 2003 The Delphi Technique The Delphi technique comprises the solicitation and comparison of anonymous judgments on the topic of interest through a set of sequential questionnaires that are interspersed with summarized information and feedback of opinions from earlier responses 30/42 Copyright Atomic Dog Publishing, 2003 The Delphi Technique (cont.) The advantage is having several judges while removing the biasing effects that might occur during face-to-face interaction Basic approach is to collect anonymous judgments from group members by mail questionnaire A process administrator then summarizes the responses as the group consensus, and feeds this summary back along with a second questionnaire for reassessment Respondents independently evaluate their earlier responses Underlying belief is that the consensus estimate will result in a better decision after several rounds of anonymous group judgment 31/42 Copyright Atomic Dog Publishing, 2003 The Nominal Group Technique (NGT) The NGT comprises processes that bring people together but do not allow them to communicate verbally. Thus, the collection of people is a group “nominally,” or “in name only” 32/42 Copyright Atomic Dog Publishing, 2003 The Nominal Group Technique (NGT) (cont.) A structured group meeting proceeds as follows: A group of individuals (7 to 10) sit around a table but do not speak to one another Each person writes ideas on a pad of paper A recorder writes the ideas on a flip chart in full view of the entire group This continues until all of the participants indicate that they have no further ideas to share Each idea receives attention before a vote is taken Each participant, in private, selects priorities by ranking or voting The group decision is the mathematically pooled outcome of the individual votes 33/42 Copyright Atomic Dog Publishing, 2003 Information Technology and Decision Making Copyright Atomic Dog Publishing, 2003 Information Technology and Decision Making In decision-making situations, managers can’t possibly use “all available information” The challenge for managers is to collect, process, and warehouse the most relevant information to make effective decisions in the present and future Tools for warehousing and retrieving information for use throughout their firms: Data warehousing Data mining Data marts Search engines Software agents 35/42 Copyright Atomic Dog Publishing, 2003 Attributes of Useful Information Accessible Timely relevant Accurate Verifiable Complete Clear 36/42 Copyright Atomic Dog Publishing, 2003 Information Sharing Organizations that train people in the value of information and how to use it and share it gain competitive advantage over those who don’t 37/42 Copyright Atomic Dog Publishing, 2003 Decision Support Systems (DDS) Copyright Atomic Dog Publishing, 2003 Decision Support Systems (DDS) DDS is an interactive information system that enables managers to gain instant access to information in a less structured format than a traditional management information system or database Must obtain information about the firm, competitors, and the business environment May include links to the World Wide Web, and have built-in artificial intelligence that adjusts to group behaviors and needs DDS is inherently user friendly Copyright Atomic Dog Publishing, 2003 39/42 Decision Support Systems (cont.) Supports managerial skills at all levels of decision making by providing instant response to managers’ information needs An executive information system (EIS) is a user-friendly DDS designed specifically for executives Consolidate the analysis provided by a DDS, interpret it considering the firm’s strategic goals, and present the results of executives in an easily understandable format 40/42 Copyright Atomic Dog Publishing, 2003 Expert Systems and Artificial Intelligence Artificial intelligence allows computers to solve problems involving imagination, abstract reasoning, and common sense Expert systems refers to computer systems that can make decisions without human interaction, by imitating human thinking and offer advice or solutions to complex problems in much the same way as a human expert would 41/42 Copyright Atomic Dog Publishing, 2003 End of Chapter 7 Copyright Atomic Dog Publishing, 2003
