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
