Software Development Target: Develop high quality software that meets customers' truly needed in the budget.
Let the data speak:
The factor of the project is delayed and does not reach the target: 1. Lack of user input: 13% 2 of all items. Incomplete demand and specification: 12% 3 of all items. Constantly changing requirements and specifications: 12% 4 of all projects. Unreasonable progress and time segmentation: 4% 5 of all projects. People and resources: accounting for 6% of all projects. Technical skills are not enough: 7% of all projects
Successful factors: 1. User intervention: 16% 2 of all items. Administrative management support: 14% 3 of all projects. Demand statement: 12% of the 12% demand errors in total submission defects are the highest, accounting for about 1/3 demand error repair: the repair cost / demand phase of the maintenance phase = 200/1
Therefore, it is more than 30% of the impact of demand management on the project.
