Business analysts use 'Acceptance and Evaluation Criteria' to measure the quality of requirements. This technique involves setting specific criteria that the requirements must meet to be accepted. These criteria are used to evaluate whether the requirements are well-defined, clear, and meet the necessary standards for successful project outcomes. By establishing these criteria, BAs can ensure that the requirements are aligned with business objectives and can be tested against predefined standards. Reference: The use of acceptance and evaluation criteria is a common practice in business analysis for ensuring requirement quality and is discussed in various business analysis resources, including the Business Analysis Body of Knowledge (BABOK) guide1.
