According to the PMI Guide to Business Analysis, the business analyst's role during acceptance testing is to ensure that the solution meets the requirements and expectations of the stakeholders, and that it delivers the intended business value. One of the ways to do this is to assist the quality assurance department by defining acceptance criteria, which are measurable and observable conditions that must be met for the solution to be accepted by the stakeholders. Acceptance criteria help to verify and validate that the solution meets the requirements and conforms to the quality standards. Executing all acceptance tests on behalf of the user community, delegating execution of acceptance testing and defect identification to users, or acting as a resource only when users encounter difficulties while performing tests are not effective strategies for the business analyst's role during acceptance testing, as they do not ensure the involvement and satisfaction of the stakeholders, or the alignment of the solution with the business needs and objectives.
