The RGQ Organization utilizes a change log.

A change log is a tool that helps to manage and monitor the changes that affect the requirements, the solution, or the project. A change log tracks all characteristics and status of changes that have been received, such as the source, description, priority, impact, approval, and resolution of the changes. A change log can help to ensure that the changes are properly documented, communicated, and controlled, and that they are aligned with the stakeholder needs and expectations. References: BABOK Guide v3, page 54; CBAP / CCBA Certified Business Analysis Study Guide, page 161.
