Requirements quality refers to the extent to which the requirements for a project align with the business goals and support the successful execution of the project. There are several criteria that are commonly used to evaluate the quality of requirements, including:

1. Completeness: Do the requirements cover all the necessary aspects of the project?
2. Consistency: Are the requirements consistent with each other and with the overall project goals?
3. Clarity: Are the requirements clear and easy to understand?
4. Feasibility: Are the requirements feasible to implement within the constraints of the project?
5. Testability: Can the requirements be tested to ensure they are being met?
6. Traceability: Can the requirements be traced back to their source and traced forward to their implementation?
7. Prioritization: Are the requirements prioritized in a logical and meaningful way?
8. Accuracy: Are the requirements accurate and free from errors?
9. Relevance: Are the requirements relevant to the business goals and objectives of the project?
10. Maintainability: Can the requirements be maintained and updated as needed over the course of the project?
