Fundamentals of Decision
Making
Decisions are choices of actions from among
multiple feasible alternatives.
Making decisions is one of the primary activities
of senior managers.
Decisions are also made by managers at all
levels and by associates in high-involvement
organizations.

Gathering Information
Sensing
Intuition
A decision style
focused on gathering
concrete information
directly through the
senses, with an
emphasis on practical
and realistic ideas.
A decision style
focused on developing
abstractions and
figurative examples for
use in decision making,
with an emphasis on
imagination and
possibilities.
10-9
Intuition Style
Valuable when:
•
•
•
•
•
A high level of ambiguity exists
Few or no precedents exist
Facts are limited
Facts don’t clearly indicate which way to go
Time is limited and there is pressure to make the
right decision
• Several plausible alternative solutions exist with
good arguments for each
10-10
Evaluating Alternatives
Thinking
Feeling
A decision style
focused on objective
evaluation and
systematic analysis.
A decision style
focused on subjective
evaluation and the
emotional reactions of
others.

What are your thoughts about the comment that
many accountants believe that more data is
better and they hide behind “a mass of data”?
What are your thoughts that some marketers
have “blind spots” when it comes to having to

Degree of Acceptable Risk
• Risk exists when the outcome of a chosen
course of action is not certain
• Risk-taking propensity (Willingness to take
chances)

Cognitive Biases
Ease of recall bias
Confirmation bias
Relying too much on
information that is
easy to recall from
memory
Seeking information
that confirms early
beliefs and ideas
Sunk-cost bias
Cognitive Mental shortcuts involving
Biases simplified ways of thinking
Not treating past
investments (time,
effort, money) as sunkcosts when deciding to
continue an investment
Anchoring bias
Emphasizing too
much the first piece
of information
encountered

• What role do “sunk costs” play in many decisions?
• Why would someone like Rob Hall ignore his predetermined turnaround time?
• Have you experienced the “perils of sunk cost” in
your work or personal lives? Give examples.

Group Decision Making
• Some members may arrive with their own
expectations, problem definitions, and predetermined solutions
• Some members may have given more thought
to the decision situation and what is to be
accomplished
• Focus of the team leader may be in developing a
collaborative team rather than developing
individual decision making skills

Vroom-Yetton Method
Victor Vroom
Philip Yetton
Requires managers to diagnose the problem situation and
then determine the extent to which associates will be
involved in the decision-making process. The involvement
depends on the probable effect participation will have on:
• the expected quality of the decision
• the acceptance or commitment needed from associates to
implement the solution
• the amount of time available (and needed) to make the
decision.

Vroom-Yetton Method
Questions asked to determine level of associate
involvement in decision making
A. Is there a quality requirement such that one solution is likely to
be more rational than another solution, or will any number of
solutions work reasonably well?
B. Do I have sufficient information to make a high-quality decision?
C. Is the problem structured (do I know the question to ask and
where to look for relevant information)?
D. Is acceptance of the decision by associates critical to effective
implementation?
E. If I were to make the decision by myself, is it reasonably certain
that it would be accepted by my associates?
F. Do the associates share the organizational goals to be attained in
solving this problem?
G. Is conflict among associates likely in preferred solutions?

Value of Individual vs. Group
Decision Making
Important considerations for judging the overall
value of group decision vs. individual decision
making include:
Time
Cost
Nature of the
Problem
Satisfaction and
Commitment
Personal Growth
10-24
Group Decision Making
Advantages
Disadvantages
Can accumulate more
knowledge and facts and
generate better alternatives.
Take more time to reach
decisions than do individuals.
Often display superior
judgment when evaluating
alternatives.
Involvement in decisions leads
to a higher level of acceptance
and satisfaction.
Can result in growth for
members of the group.
Social interactions may lead to
premature compromise.
Often dominated by one or two
“decision leaders.”
Managers may rely too much on
group decisions – lose their
own skills.

The Strategic Lens
1. You are a manager of a unit with 25 associates. You
have just been informed that you must lay off 20% of
the associates in your unit. What process will you
follow to make the decision and implement it?
2. If you made a decision that your manager told you was
important for the organization and later you learned
that you made an error in that decision, what actions
would you take? Assume that others will not notice the
error for some time.
3. You make decisions on a daily basis. Do you find it
difficult to make decisions, especially those of
importance? What can you do to improve your
decision-making abilities?
