3. Definition
Decision making can be regarded as the
mental processes (cognitive process) resulting
in the selection of a course of action among
several alternatives.
Every decision making process produces a final
choice.
The output can be an action or an opinion of
choice.
4. Problem Analysis vs. Decision
Making
It's important to differentiate between problem
analysis and decision making.
The concepts are completely separate from one
another.
Problem analysis must be done first, then the
information gathered in that process may be
used towards decision making.
5. Problem Analysis
Analyze performance, what should the results be against what they
actually are
Problems are merely deviations from performance standards
Problem must be precisely identified and described
Problems are caused by some change from a distinctive feature
Something can always be used to distinguish between what has and
hasn't been effected by a cause
Causes to problems can be deducted from relevant changes found
in analyzing the problem
Most likely cause to a problem is the one that exactly explains all the
facts
6. Decision Making
Objectives must first be established
Objectives must be classified and placed in order of importance
Alternative actions must be developed
The alternative must be evaluated against all the objectives
The alternative that is able to achieve all the objectives is the
tentative decision
The tentative decision is evaluated for more possible consequences
The decisive actions are taken, and additional actions are taken to
prevent any adverse consequences from becoming problems and
starting both systems (problem analysis and decision making) all
over again
7. Decision Support System
A decision support systems (DSS) is a
computer-based information system that
supports business or organizational decision-
making activities.

planning levels of an organization and help to
make decisions, which may be rapidly changing
and not easily specified in advance.
