Its responsibilities include formulating quality standards, writing test cases, conducting functional and performance tests, and optimizing the product based on feedback. In government procurement projects, quality evaluation focuses on process compliance, security, and functional compatibility. KPI evaluation trees are commonly used for quantitative assessment, and a dynamic adjustment mechanism for indicators needs to be established to cope with complex demands. In addition, risk-driven testing and agile development should be combined to set up quality access control to ensure that each iteration version meets expectations. The multi-dimensional quality assurance and verification scoring mechanism can effectively enhance product reliability and reduce project risks.
