Which process involves updating the project management plan?

The process that involves updating the project management plan is Control Scope. This process is crucial in project management as it ensures that all the project work aligns with the agreed-upon scope. When changes occur, such as scope adjustments due to stakeholder feedback or unforeseen project challenges, the Control Scope process allows project managers to evaluate these changes.

In executing Control Scope, any modifications or clarifications to the project scope must be documented, leading to updates in the project management plan. This ensures that everyone involved in the project stays informed and aligned with the current scope, objectives, and deliverables. By managing changes and preventing scope creep, the project manager can keep the project on track, ensuring it meets its goals and stakeholder expectations.

While other processes like Control Schedule and Verify Scope play important roles in managing specific aspects of the project, they do not primarily focus on updating the overall project management plan as Control Scope does. Define Activities, on the other hand, is concerned with outlining the tasks required for project completion, which also does not encompass the scope management updates.
