You work as a project manager for BlueWell Inc. You have declined a proposed change request because of the risk associated with the proposed change request. Where should the declined change request…

The change request log (also called the change log) is the designated document for recording all submitted change requests and their disposition status, including declined requests. This ensures traceability, supports audits, and provides a historical record of all change activity during the project lifecycle.

Lessons learned capture knowledge and insights gained from project experience; while a declined change may eventually inform lessons learned, the change log is the designated tracking document for individual change request records.

Project archives are an end-of-project repository for completed records and deliverables, not the active mechanism used during execution for tracking individual change request decisions.

Project document updates is a general PMBOK output category describing which documents get revised - it is not itself a specific document where declined change requests are stored.
