Change Management

Change Management

Change management is vital to every stage of the patch management process. As with all system modifications, patches and updates must be performed and tracked through the change management system. It is highly unlikely that an enterprise-scale patch management program can be successful without proper integration with the change management system and organisation.

Change management patches
Like any environmental changes, patch application plans submitted through change management must have associated contingency and backout plans. What are the recovery plans if something goes wrong during or as a result of the application of a patch or update? Also, information on risk mitigation should be included in the change management solution. For example, how are desktop patches going to be phased and scheduled to prevent mass outages and support desk overload? Monitoring and acceptance plans should also be included in the change management process. How will updates be certified as successful? There should be specific milestones and acceptance criteria to guide the verification of the patches’ success and to allow for the closure of the update in the change management system (e.g. no reported issues within a week of patch application).
