STAGES OF DECISION MAKING• INTELLIGENCE: Collect information;

identify problem• DESIGN: Conceive alternatives; select criteria• CHOICE: Use criteria to evaluate alternatives;

select • IMPLEMENTATION: Put decision into effect;

allocate resources; control*

SOURCE: Simon, The New Science of Management Decision (1960)

• RATIONAL MODEL: Assumes comprehensive rationality - comprehensive search for alternatives, their systematic evaluation against objectives, choosing the alternative that maximises value.

• Satisficing Models: Based on the concept of bounded rationality - people do not have the cognitive capacity to be comprehensively rational; hence they ‘satisfice’.

• Political Model
