Problem solving approach:
1. Gather the facts 2. Analyze the facts 3. Make a decision
Preliminary investigation
Feasibility study
Detail analysis
Review the current system
Requirements determination
Recommend a solution
Deliverable: Requirements document. Feasibility study & Preliminary Investigation report as needed.
