What is the workflow you follow to design the software you're about to write? [closed]

Answer 1

1. Write the use cases like you did.
2. Pick 1 of the uses case and implement it completely, and implement nothing else. This includes unit tests, help and error handling -- everything. Call this version 1.
3. Implement the next use case. This may be just adding code, or may require a complete redesign. It's ok, you know what your doing now. Make a new release.
4. Repeat step 3.
