Request for Change (RFC)
A description of a proposed change used to initiate change control. It contains details of the proposed change, including the business case, risk assessment, and implementation plan.
Impact
The RFC is the control document. It ensures changes are thought through before execution.
Weinto take
The "RFC" should be a Pull Request. We don't fill out PDF forms for changes; we update the code (or infrastructure config) in a branch and open a PR. The PR description is the RFC. The code review is the CAB meeting.
