Recommended demand development process
1. Define the view and range of the project
2. Determine user classes
3. Determine the appropriate representative in each user class
4. Determine demand decision makers and their decision-making process
5. Choose the requirements you use.
6. Use the demand acquisition technology to develop and set priority as the usage examples of the system
7. Collect information from quality properties from users and other non-functional requirements
8. Detailed developments use instances to integrate them into the necessary functional requirements
9. Description and functional requirements of the review instance
10. If necessary, develop analytical models to clarify the needs of demand acquisition
11. Develop and evaluate user interface prototypes to help imagine still not understanding
12. Develop a concept test case from the instance
13. Use test example to demonstrate the use of instances, functional requirements, analysis models and prototypes
14. Repeat 6 ~ 1 3 before the design and constructing system continues
