Agile Practices for Small and Medium-sized Projects No. 3 (About Requirements)

**The development method is a systematic project that requires the cooperation of all project activities. **

This experience is based on the practice summary of two small and medium-sized projects (one 2000 Manday, one 1500 Manday) in the past two years, and I hope to discuss and make progress with you.

- Need to have clear requirements (this is the hardest part of the project)
- Requirements management process
> Gather requirements
> Identify key use cases
> Identify details
- Sequence requirements with the help of project owner
- Embrace requirements changes
- Control requirements changes
> Reach a consensus with the project owner: Develop a just-right system, or a perfect system
> Statistics from the American Standish Group show that commonly used functions in software account for only 20% of all functions, and rarely used or unused functions account for 64%
