Approaches to problem solving
Four stages of problem solving
Analysis
- Understanding all aspects of the problem and state what is required of the solution
Design
- Decide what has to be done to achieve the solution
Development
- Build the solution with either off-the-shelf or custom made hardware and software
Evaluation- Determine whether the solution has solved the original problem
