Which document outlines the changes made to requirements during a project?

The document that outlines the changes made to requirements during a project is the Change Log. A Change Log serves as a systematic record where all requested, implemented, or rejected changes to the project requirements are documented. It provides a clear audit trail of modifications over the course of the project, making it an essential tool for tracking how and why requirements evolve.

Having a Change Log is crucial for maintaining clarity and communication among stakeholders, as it ensures that everyone is aware of what changes have occurred, under what circumstances, and the implications of those changes on the project. This way, if disputes arise or if retrospective analysis is needed, the Change Log can serve as a reliable reference.

In contrast, the Requirement Specification Document primarily captures the initial detailed requirements but does not specifically track changes over time. The Project Schedule focuses on the timing and sequencing of project tasks rather than on individual requirement modifications. Status Reports provide general updates on project progress and status, but they do not specifically detail changes to requirements.
