Decision Making Models
Introduction
Decision making is the process of selecting the best alternative from the available set
of alternatives.
Decision making involves three activities: (Herbert A Simon)
o Intelligence Activity
o Designing Activity
o Choice Activity
7-Steps Model
1. Establish objectives
2. Classify and prioritize objectives
3. Develop alternative actions
4. Evaluate alternatives against objectives
5. Tentative decision to most appropriate alternative
6. Evaluation of tentative decision for more consequences
7. Decisive action is taken and additional actions to prevent consequences
Rational Model
Consists of a structured four-step sequence:
o identifying the problem
o generating alternative solutions
o selecting a solution
o implementing and evaluating the solution
Techniques used in rational model of decision-making are:
o SWOT analysis
o Pareto analysis
o Decision trees
o Management by Objectives (MBO)
o Program (or Project) Evaluation and Review Technique (PERT)
Simon’s Normative Model
This model based on premise that decision making is not rational
The model state that decision making is characterized by:
o limited information processing
o use of rules of thumb or shortcuts
o satisfying
Group Decision Making Model
Groups can accumulate more knowledge and facts
Groups have a broader perspective and consider more alternative solutions.
Individuals who participate in decisions are more satisfied with the decision and are
more likely to support it.
Clinical Decision Making Model
Banning described three clinical decision making models:
1. information-processing model that uses a scientific hypothetic-deductive, quantitative
approach,
2. the intuitive-humanistic model that focuses on intuition and how the knowledge
gained from nursing experience enriches the clinical decision making process and
3. the clinical-decision model that uses both hypothetico-deductive and pattern
recognition.
Critical pathways are used as a technique in clinical decision making.
Conclusion
Decision-making models offer analytical tools which can be combined to provide
useful insights.
In the real world, most of our decisions are made unconsciously in our mind.
