After reading the material in this chapter, you should be able to:
• Compare and contrast the rational model of decision making, Simon’s normative model, and the garbage can model
• Identify common decision-making biases.• Discuss knowledge management techniques used by
companies to increase knowledge sharing.• Describe the model of decision-making styles, the role of
intuition in decision-making and the stages of the creative process.
• Summarize the pros and cons of involving groups in the decision-making process.
• Contrast brainstorming, the nominal group technique, the Delphi technique, and computer-aided decision making.

Models of Decision Making
• Decision making- identifying and choosing solutions that lead to
a desired result
![Page 4: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/4.jpg)
10-4
Models of Decision Making
• The Rational Model - proposes that managers use a logical four-
step approach to decision making.
1.Identifying the problem2.Generating alternative solutions3.Selecting a solution4.Implementing and evaluating the solution
![Page 5: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/5.jpg)
10-5
Rational Model
• Identifying the Problem- Problem – exists when the actual situation and
the desired situation differ
• Generating Solutions- For routine decisions alternatives are readily
available through decision rules
![Page 6: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/6.jpg)
Methods for Identifying Problems
1. Assume the recent past is the best estimate of the future
2. Use projections or scenarios3. Rely on the perceptions of others

10-7
Rational Model
• Selecting a Solution- Want to maximize the expected utility of an
outcome- People vary in their preferences for safety or
risk- Ethics should be considered
![Page 8: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/8.jpg)
10-8
Rational Model
• Selecting a Solution- Evaluating alternatives assume they can be
judged according to some criteria- Assumes valid criteria exists- Each alternative can be compared to these
criteria- Decision maker actually uses the criteria
![Page 9: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/9.jpg)
10-9
Rational Model
• Implementing and Evaluating the Solution
- After solution is implemented, the evaluation phase is used to evaluate its effectiveness
- Optimizing – choosing the best possible solution
![Page 10: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/10.jpg)

Question?
Gloria is never happy with "good enough" solutions. She is determined to find the best possible solution in solving her problems. What Gloria is doing is described as
A.OptimizingB.BrainstormingC.RationalizingD.Satisfying
![Page 11: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/11.jpg)
Nonrational Models of Decision Making
• Nonrational models - decision models that explain how decisions
are actually made
1.Decision making is uncertain2.Decision makers do not possess complete
information3.Difficult for managers to make optimal
decisions
10-11
![Page 12: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/12.jpg)
10-12
Simon’s Normative Model
• Bounded rationality - constraints that restrict rational decision
making
• Satisficing - choosing a solution that meets a minimum
standard of acceptance
![Page 13: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/13.jpg)
10-13
Simon’s Normative Model
Most frequent causes of poor decision making
• Poorly defined processes and practices• Unclear company vision, mission, and goals• Unwillingness of leaders to take responsibility• Lack of reliable, timely information
![Page 14: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/14.jpg)
Garbage Can Model
• Garbage Can Model - decision making is sloppy and haphazard- decisions result from complex interaction of
four streams of events: problems, solutions, participants and choice opportunities
10-14
![Page 15: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/15.jpg)
Implications of the Garbage Can Model
1. Many decisions are made by oversight2. Political motives frequently influence
decision makers3. Decision making process is difficult to
load4. Important decisions are more likely to be
solved

Decision-Making Biases
• Judgmental heuristics - rules of thumb or shortcuts that people use to
reduce information processing demands.
![Page 17: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/17.jpg)

Group Problem Solving Techniques
• Computer-aided decision making- reduces consensus roadblocks while
collecting more information in a shorter period of time
![Page 37: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/37.jpg)
10-37
Computer-aided Decision Making
• Chauffeur-driven systems - ask participants to answer predetermined
questions on electronic keypads
• Group-driven meetings - conducted in special facilities equipped with
individual workstations that are networked to each other

10-39
Making Tough Calls
• Jim Collins – studied the inner workings of organizations to understand how they became great
• People decisions are most important- Making the right choices on who to can
adapt to a changing environment has more long term impact than decisions about strategy.
![Page 40: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/40.jpg)
10-40
Making Tough Calls
• Once good people are in place, how do you make good decisions?- Strive for conflict, challenging assumptions and
ways of thinking
• Consensus is not necessary- Once an issue has been debated the leader
needs to make the decision- Having the right people in place means they’ll
get behind a decision even if there is still some disagreement
![Page 41: Making Decisions Chapter Ten Copyright © 2010 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin](https://reader035.vdocuments.mx/reader035/viewer/2022062322/56649e495503460f94b3c1e8/html5/thumbnails/41.jpg)

• Pitfall: Sunk-cost syndrome- Device: Burn the boat
• Pitfall: Yes-man echoes- Device: Voice questions, not opinions
