Cevap
The correct operational order is: 1) Submit a formal Request for Change (RFC); 2) Perform an impact analysis, risk assessment, and establish a rollback procedure; 3) Present the proposed change to the Change Advisory Board (CAB) for authorization; 4) Execute the upgrade during an authorized maintenance window; 5) Conduct post-implementation verification testing and update configuration baseline documentation.
The standard change management lifecycle begins with RFC submission, followed by risk analysis and rollback planning. The complete proposal is then submitted to the CAB for authorization. Once authorized, implementation takes place within an approved maintenance window, followed by post-implementation validation and baseline documentation updates.
