Problem Analysis
- Define the problem.
- Eliminate all ambigous words or decisions in the problem statement.
- List the desired outputs. Prepare a sample of the output in the form it should appear.
- List the necessary inputs.
|
| |
Algorithm Design
- Write down a 3 to 7 step solution in general terms using Warnier-Orr diagram, Flow chart, or other diagram.
- Refine each of the steps in the previous solution into a sequence of 2 to 7 more detailed steps.
- Repeat the above step until sufficient detail is provided.
- Test the design with structured walkthroughs.
|
Computer Implementation
- Convert the Warnier-Orr diagram, Flow chart, or other diagram of the algorithm into instructions for a specific computer language.
- Test the program with carefully designed test data. Check for syntax and logic errors.
