Pay attention to the Software Requirement Analysis

1. Try to subtract the demand from the customer, and split the overall requirement into 2 ~ Phase 3 and Phase 1 are only the most basic and necessary requirements for development.
2. Do not forget to calculate the cost of the demand document and product plan.
3. requirement change process specification (you must declare at the beginning of 1.1, or even write it in the contract .)

A. Any request change must be submitted in writing and must have the signature or seal of both parties.

B. The results, suggestions and changes of all discussions on relevant requirements must be prepared in writing, and no oral expression in the telephone or conference has any effect.

C. it is recommended that you do not frequently propose demand changes after the first stage of requirement determination. In the first stage, only the most basic and necessary demand functions are developed, plan other independent new requirements for development in the next phase.

4. Pay attention to the estimated construction period, which tests the capabilities and experience of a Project Manager in the demand phase.
