Decision Making by Individuals & Groups Chapter 10 Nelson & Quick Decision Making by Individuals & Groups

The Decision-Making Process Programmed Decision - a simple, routine matter for which a manager has an established decision rule Nonprogrammed Decision - a new, complex decision that requires a creative solution 2

The Decision- Making Process Recognize the problem and the need for a decision The Decision- Making Process Identify the objective of the decision Gather and evaluate data and diagnose the situation List and evaluate alternatives 3

The Decision- Making Process Select the best course of action The Decision- Making Process Implement the decision Gather feedback Follow up 4

Models of Decision-Making Effective Decision a timely decision that meets a desired objective and is acceptable to those individuals affected by it Rational Model Bounded Rationality Model Garbage Can Model 5

Rationality - a logical, step- by-step approach to decision making, with a thorough analysis of alternatives and their consequences Rational Model 1. The outcome will be completely rational 2. The decision maker uses a consistent system of preferences to choose the best alternative 3. The decision maker is aware of all alternatives 4. The decision maker can calculate the probability of success for each alternative 6

Bounded Rationality - a theory that suggests that there are limits upon how rational a decision maker can actually be Bounded Rationality Model 1. Managers suggest the first satisfactory alternative Satisfice – to select the first alternative that is “good enough,” because the costs in time and effort are too great to optimize 7

Bounded Rationality - a theory that suggests that there are limits upon how rational a decision maker can actually be Bounded Rationality Model 1. Managers suggest the first satisfactory alternative 2. Managers recognize that their conception of the world is simple 3. Managers are comfortable making decisions without determining all the alternatives 4. Managers make decisions by rules of thumb or heuristics Heuristics – shortcuts in decision making that save mental activity 7

random and unsystematic Garbage Can Model Solutions Choice opportunities Garbage Can Model - a theory that contends that decisions in organizations are random and unsystematic Problems Participants From M.D. Cohen, J.G. March, and J.P. Olsen in Administrative Science Quarterly 17 (March 1972) 1.25. Reprinted by permission of the Administrative Science Quarterly 8

Risk and the Manager Risk Aversion - the tendency to choose options that entail fewer risks and less uncertainty Risk takers accept greater potential for loss tolerate greater uncertainty more likely to make risky decisions Evidence: Successful Managers Take Risks 9

Escalation of Commitment The tendency to continue to commit resources to a failing course of action Why it occurs humans dislike inconsistency optimism control sunk costs How to deal with it split responsibility for decisions provide individuals with a graceful exit have groups make the initial decision 10

Cognitive Style Cognitive Style - an individual’s preference for gathering information and evaluating alternatives Jungian theory offers a way of understanding and appreciating differences among individuals.

Influences on Decision-Making Intuition - fast, positive force in decision making utilized at a level below consciousness, involves learned patterns of information Creativity - a process influenced by individual and organizational factors that results in the production of novel and useful ideas, products, or both Before & After, Inc., is a creativity firm dedicated to helping people and organizations think outside the box.

Four Stages of Creative Process Preparation experience/ opportunity to build knowledge base Incubation reflective, often unconscious thought Illumination insight into solving a problem Verification thinking, sharing, testing the decision

Influences on Creativity Individual examples Cognitive Processes Divergent Thinking Associational Abilities Unconscious Processes Personality Factors breadth of interests high energy self-confidence Organizational examples Flexible organization structure Participative decision making Quality, supportive relationships with supervisors

Organizations Can Facilitate Creative Decision Making Reward creativity Allow employees to fail Make work more fun Provide creativity training Vary work groups (internal/external) Encourage creative stimuli (music, art, etc.)

Participative Decision Making Individuals who are affected by decisions influence the making of those decisions Organizational Foundations Participative, supportive organizational culture Team-oriented work design Individual Prerequisites Capability to become psychologically involved in participative activities Motivation to act autonomously Capacity to see the relevance of participation for one’s own well-being

Group Decision-Making Role of synergy - a positive force that occurs in groups when group members stimulate new solutions to problems through the process of mutual influence and encouragement in the group Role of social decision schemes - simple rules used to determine final group decisions (prediction 80% correct) Majority Wins Truth Wins Two-thirds Majority First-shift

Group Decision Making Advantages Disadvantages 1) more knowledge through pooling of group resources 2) Increased acceptance & commit- ment due to voice in decisions 3) greater understanding due to involvement in decision stages Advantages 1) pressure in groups to conform 2) domination by one forceful member or dominant clique 3) amount of time required, because group is slower than individual to make a decision Disadvantages

Group Phenomenon Groupthink - a deterioration of mental efficiency, reality testing, and moral judgment resulting from in-group pressures Group Polarization - the tendency for group discussion to produce shifts toward more extreme attitudes among members

Preventing Groupthink Ask each group member to act as critical evaluator Have the leader avoid stating his opinion prior to the group decision Create several groups to work simultaneously Appoint a devil’s advocate Evaluate the competition carefully After consensus, encourage rethinking the position From Janis, Irving L., Groupthink: Psychological Studies of Policy Decisions and Fiascoes, Second Edition.
