Under which process do updates of the project management plan go through via a change request?

The process through which updates to the project management plan occur via a change request is typically associated with the organization's change control process. This process provides a structured approach for managing changes to the project scope, schedule, and other critical elements of the project management plan. It allows for proper evaluation, approval, and documentation of any proposed changes, ensuring that all impacts are considered before implementation.

When a change request is initiated, it undergoes a formal review to assess its implications on project objectives, stakeholder requirements, and overall project alignment. This ensures a controlled and organized method for incorporating changes, mitigating risks associated with project deviations, and maintaining project integrity.

In contrast, the project execution process primarily deals with carrying out the work defined in the project management plan, while the change management process is a broader term that encompasses the steps needed to manage change effectively. Quality management focuses on ensuring that project deliverables meet the defined quality standards but does not specifically address changes to the management plan itself. Hence, the organization's change control process is the most accurate context for processing updates to the project management plan.
