According to the PMBOK Guide's Change Management Process, when a new change is suggested, it should first be identified as a change request by any stakeholder. The project manager and/or project team members then analyze the impact of the change request on the project. This includes documenting the change request and presenting it to the Change Control Board (CCB) for review and decision1. Accepting a suggestion without a formal change request could bypass necessary analysis and documentation processes that ensure the change is beneficial and does not introduce unforeseen risks or issues.
