What is the significance of maintaining a change log in project management professional (PMP) practices?

Maintaining a change log in project management professional (PMP) practices is significant because it helps track and document all changes made throughout a project. This allows for better communication, transparency, and accountability among team members, stakeholders, and clients. It also helps in identifying the impact of changes on the project timeline, budget, and scope, ultimately leading to better decision-making and risk management.
