Decision Making & Problem Solving Process
Potential Problems and opportunities are identified
and defined
Alternative solutions to the problem are developed
Select a course of action
Solution put into effect
Evaluate the implementation

Optimization and Heuristic
Optimization Model: find the best solution, helping individuals or organizations meet goals.
Heuristics: commonly accepted guidelines or procedures that usually find a good solution, but not necessarily the optimal solution

Reports
Scheduled Reports are produced periodically on a schedule; daily, weekly, monthly, quarterly, annually, etc.
Demand Reports are developed to get certain information at a person’s request.
Exception Reports are automatically produced when a situation is unusual or requires action.
