Decision making
Decision making
‘The process by which managers identify
organisational problems and try to


resolve them.’

© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

3


Nature of managerial decision
making
Types of problems faced:
• Crisis problems
Serious. Requires immediate action.

• Non-crisis problems
Requires resolution but not both immediate and
important.

• Opportunity problems
Opportunity for organisational gain IF appropriate
action taken.

Nature of managerial decision
making
Decision making situations:
• Programmed decisions
Routine, repetitive, well-structured situations by use

of pre-determined decision rules.

• Non-programmed decision making
Pre-determined decision rules are impractical due to
novel &/or ill-structured situations.

• The element of risk
Possibility that a chosen decision could lead to
losses rather than intended results.

5


Managers as decision makers
Models of managerial decision making:
• Rational model
Model suggesting managers engage in completely rational
decision processes, ultimately making optimal decisions, and
possess and understand all information relevant to their
decisions at the time they make them.

• Non-rational models
Models suggesting information gathering and processing
limitations make it difficult for managers to make optimal
decisions.
© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

6



Non-rational models
• Satisficing model
Managers seek alternatives only until they find one
which looks satisfactory, rather than seeking an
optimal decision.

• Incremental model
Managers make the smallest response possible to
reduce the problem to at least a tolerable level.

• Rubbish bin model
Managers behave in virtually a random way in
making non-programmed decisions.

Effective decision making
Steps to effective decision making:
• Identify the problem
Scan for change, categorise as problem/non-problem,
diagnose nature and cause.

• Generate alternative solutions
Uncritically brainstorm to develop alternatives, combine &
improve ideas.

• Evaluate & choose an alternative

Feasibility, quality, cost, reversibility, ethics, acceptability.

• Implement and monitor
Plan and implement, evaluate effect on others, monitor.

Barriers to effective decision
making

• Complacency

Individuals either do not see signs of danger/opportunity or,
avoid them.

• Defensive avoidance

Individuals either deny the importance of a danger
/opportunity or deny any responsibility for taking action.

• Panic

Individuals become so upset they frantically seek a way to
solve the problem.

• Deciding to decide

Decision makers accept the challenge and follow an effective
decision-making process.

13


Decision making bias
• Framing
Tendency to make different decisions depending on
how a problem is presented.

• Prospect theory
Decision makers find the prospect of an actual loss
more painful than giving up the possibility of a gain.

• Representativeness
Tendency to be overly influenced by stereotypes in
making judgements about the likelihood of
occurrences.
© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

14


Decision making bias
• Availability
Tendency to judge the likelihood of an occurrence on the
basis of the extent to which other like instances can easily be
recalled.


• Anchoring & adjustment
Tendency to be influenced by an initial figure, even when the
information is largely irrelevant.

• Overconfidence
Tendency to be more certain of judgements regarding the
likelihood of a future event than one’s actual predictive
accuracy warrants.
© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

15


Decision escalation
‘Escalating commitment
and accelerating losses’
Non-rational escalation: increased
commitment of resources beyond rational limits
Sunk costs: not recoverable, and
should not influence decision-making

Advantages:
• More information
available
• Wide range of

Creativity in decision making
‘Creativity is the cognitive process of
developing an idea, concept, commodity or
discovery viewed as novel by its creator or
target audience.’

© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

21


Creativity in decision making
Creativity requires both:
• Divergent thinking
Attempting to move logically to a problem solution.

• Divergent thinking
Generating new ways of viewing a problem and
seeking novel alternatives.


© 2003 McGraw-Hill Australia Pty Ltd. PowerPoint

22


Creativity in decision making
Three basic ingredients necessary for creativity:
• Domain-relevant skills
Expertise in a field relevant to the problem.

• Creativity-relevant skills
Skills in generating novel ideas, approaches, modes
of thinking about problems.

• Task motivation
Interest in the task for its own sake, a desire to
resolve the problem.
