Symptoms of Software Development Problems
- Inaccurate understanding of end user requirements

- Modules cannot be combined
- Software is difficult to maintain and expand

- Unacceptable Software Performance
- The members of the project team are independent of each other, so they cannot reproduce who, when, and where, and why they have modified things.
- Unreliable establishment-release process
Root Cause of the above problem
Root causes of Software Development Problems
- Inadequate Demand Management

They are called "best practice" not because we can calculate their value, but because they are widely used by successful organizations in the industry.
