Step-by-step explanation:
The main purpose of using a change management process is to document all modifications and formalize their approval (Option D). Change management ensures that any adjustments to the project are meticulously recorded, evaluated, and authorized by relevant stakeholders before implementation. This process includes assessing the impact of the changes, updating project documents, and ensuring that everyone involved is aware of how the change will affect the scope, time, and cost of the project. Unlike identifying new stakeholders or listing scope requirements, which are part of the initial project planning phase, change management is an ongoing process that continues throughout the life cycle of a project. It aims to minimize project risk by controlling how changes are introduced and communicated.
