What should a team do if a major patch release fails according to change management best practices?

Following a documented backout plan is a critical step in change management best practices when a major patch release fails. A backout plan outlines the procedures for reverting to a previous stable state of the system, ensuring that the organization can quickly restore functionality and stability without incurring extended downtime or data loss. This approach emphasizes the importance of having a pre-defined strategy in place, which allows for systematic recovery during unforeseen issues after a patch installation.

In contrast, simply reinstalling the patch without thorough documentation would lack accountability and could lead to further complications, as it does not follow structured procedures for addressing issues. Ignoring the problem entirely and monitoring the system is irresponsible, as it could allow vulnerabilities or performance issues to remain unaddressed, potentially leading to more significant problems. While contacting vendors for immediate support could be a valid action, it should typically be done in conjunction with following the established processes, rather than being the sole response to a failure.
