The project manager should review existing artifacts to get an understanding of the purpose of the project. Existing artifacts are documents or records that provide information about the project background, context, scope, objectives, requirements, stakeholders, and deliverables. They may include documents such as project proposal, project charter, business case, feasibility study, statement of work (SOW), or contract. Reviewing existing artifacts can help to clarify the project vision and expectations and provide a basis for planning and executing the project.

Explanation
The project manager should notify the functional manager that resources are released after completing a project successfully in a functional organization. A functional organization is a type of organizational structure where employees are grouped by their functions or specialties, such as finance, marketing, or engineering. In a functional organization, the functional manager has more authority and control over the resources than the project manager. Therefore, the project manager should inform the functional manager when the resources are no longer needed for the project and can be reassigned to other tasks or projects.

The project manager is creating a quality assurance plan when identifying multiple techniques that will help the project team ensure confidence and alignment with the project scope and goals during a brainstorming meeting.

A quality assurance plan can help to improve the quality of the project processes and deliverables and prevent or reduce defects or errors.
