Who controls and maintains a Contract Work Breakdown Structure (WBS)?

A Contract Work Breakdown Structure (WBS) is typically controlled and maintained by the project manager or a designated project control team. They ensure that the WBS accurately reflects the scope of the project and is updated as necessary to incorporate changes or modifications. Collaboration with stakeholders, including contract managers and team members, is essential to ensure alignment and clarity throughout the project lifecycle. Regular reviews and updates help in managing the project's progress and resources effectively.
