A QA plan, or quality assurance plan, is a document that specifies the quality standards, practices, resources, specifications, and activities for a product, service, project, or contract. A QA plan helps to ensure that the products produced during the project meet the highest quality standards and that the project objectives and customer requirements are met. A QA plan also helps to communicate the quality expectations and responsibilities to the team members and other stakeholders, and to monitor and control the quality performance throughout the project. Developing a QA plan is one of the key tasks of the project manager, as it is part of the project scope management and project quality management processes123.
