Monitoring stage
Decision makers evaluate the implementation

=Programmed decision
- Decision made using a rule, procedure, or quantitative method

=Non-programmed decision
- Decision that deals with unusual or exceptional situations
- Not easily quantifiable
Optimisation model
find the best solution, usually the one that will best help the organization meet its goals
Satisficing model?
find a good – but not necessarily the best – problem solution
Heuristics
commonly accepted guidelines or procedures that usually find a good solution
Sense and Respond (SaR) approach
-Determining problems or opportunities (sense)
-Developing systems to solve the problems or take advantage of the opportunities (respond)
