What does a change management log document?

A change management log is a crucial tool in the management of IT systems and configurations. It specifically documents all approved changes to configurations, providing a comprehensive record of modifications that are made and their associated details. This log serves several important functions:

2. Audit Trail: The log provides an audit trail for compliance and regulatory requirements, enabling organizations to demonstrate that changes have been managed in an orderly fashion.

3. Impact Analysis: By documenting approved changes, the log assists in assessing the potential impacts of changes on other systems or processes, ensuring that configurations are consistent and reliable.

4. Historical Reference: IT teams can refer back to the change management log to understand the evolution of system configurations over time, which is particularly useful during troubleshooting or when evaluating future changes.

None of these options captures the specific role of documenting approved changes, which is why the first option stands out
