Decision Making and
Problem Solving
n
Problem solving is concerned with
overcoming obstacles in the path
toward an objective.
n
Problem solving may or may not
require action.
n
A decision is an act requiring
judgment that is translated into
action.
Decision Making and
Problem Solving (cont’d)
n
Decision making is much more
comprehensive than problem
solving.
n
The terms are interrelated, but not
interchangeable.
The Significance of Decision Making
n
Decision making is the one truly
distinctive characteristic of
managers.
n
Decisions made by top managers
commit the total organization
toward particular courses of action.
The Significance of Decision Making
(cont’d)
n
Decisions made by lower levels of
management implement the strategic
decisions of top managers in the
operating areas of the organization.
n
Decisions invariably involve
organizational change and the
commitment of scarce resources.
The Scope of Decision Making
n
Individual decision making
n
Group decision making
n
Organizational decision making
n
Metaorganizational decision making

The Locus of Choice
n
Top management makes Category II
decisions.
n
Operating management makes
Category I decisions.
n
Middle management supervises the
making of Category I decisions and
supports the making of Category II
decisions.
Characteristics of Managerial Decisions
(Category II)
n
Long-range organizational objectives
n
Best choice from among a set of
alternatives
n
Decision involves organizational
change
n
Decision requires a commitment of
resources
Characteristics of Managerial Decisions
(Category II) (cont’d)
n
Choice is a means to an end, not an
end to itself
n
Decision maker tends to overestimate
success
n
Success is measurable through
objectives attainment
Perspectives on Managerial
Decision Making
n
The integrative perspective
n
The interdisciplinary perspective
n
The interlocking perspective

The Managerial
Decision-Making Process
n
Process components are decisionmaking functions.
n
Decision-making functions are highly
interrelated and interdependent.
n
The process is highly dynamic with
several subprocesses.
n
The process can accommodate several
concurrent Category II decisions.

Decision-Making Function No. 1
Setting Managerial Objectives:
n
Objectives constitute the foundation
for rational decision making.
n
Objectives are the ends for the means
of managerial decision making.
n
Attainment of the objective is the
ultimate measure of decision success.
Decision-Making Function No. 2
Searching for Alternatives:
n
The limitations of time and money
n
The declining value of additional
information
n
The rising cost of additional
information
n
Abort the search in the zone of cost
effectiveness

cost of additional information

Decision-Making Function No. 3
Comparing and Evaluating
Alternatives:
n
Alternatives result from the search.
n
There are usually three to five
alternatives.
n
One alternative is to do nothing.
n
Alternatives are evaluated using
criteria derived from the objective.
Decision-Making Function No. 3
(cont’d)
Also:
n
Evaluation should include an
anticipation of the likely outcome for
each alternative.
n
Evaluation should also anticipate
obstacles or difficulties at the time of
implementation.
Decision-Making Function No. 4
The Act of Choice:
n
The choice is the culmination of the
process, not all of it.
n
The choice confronts the decision
maker with discernible constraints.
n
The best alternative may not be readily
apparent to the decision maker.
Decision-Making Function No. 4
(cont’d)
Also:
n
n
The best choice is likely to ensue
from the right approach.
The choice should be the alternative
most likely to result in the
attainment of the objective.
Decision-Making Function No. 5
Implementing Decisions:
Decision success is a function
of decision quality
and
decision implementation.
Decision-Making Function No. 5
(cont’d)
Areas contributing to decision
success:
n
Observance of operating constraints
n
Influence of the decision maker
n
Involvement of decision
implementers
n
Absence of conflict of interest
Decision-Making Function No. 5
(cont’d)
Areas detracting from decision
success:
n
Disregard of timeliness
n
Unlimited additional information
n
Disregard of risk/reward
relationships

4. Influence of the

Decision-Making Function No. 6
Follow-Up and Control
n
Follow-up and control is essential to
ensure that an implemented decision
meets its objective.
n
Performance is measured by
observing the implemented decision
in relation to its standard derived
from the objective.
Decision-Making Function No. 6
Also:
(cont’d)
n
Unacceptable variance from standard
performance should elicit timely and
appropriate corrective action.
n
Corrective action (subprocess no. 1) may
result in the implementation of another
alternative (subprocess no. 2), which, if
not successful, may result in a revision of
the original objective (subprocess no. 3).
