Which of the following describes effective change management procedures?

Effective change management includes a backout plan to revert to a previous stable state if a new change, such as a patch, introduces issues or fails. This minimizes downtime and risk. Approving a change after deployment defeats the purpose of pre-approval processes designed to assess risk and impact. While a spreadsheet can track changes, it's not a procedure itself and lacks the enforcement mechanisms of a robust change management system. Automatically bypassing change control for security updates, while seemingly efficient, introduces significant risk by circumventing necessary testing, approval, and documentation steps that prevent unintended consequences or vulnerabilities.
