What is the most common concern when dependencies are encountered as part of change management?

Change management processes typically focus on documenting dependencies and ensuring they are met. That may involve ensuring that the appropriate version is installed or that applications are restarted in a specific order, or that a service is available that is needed for a system to successfully function. Removing dependencies is unlikely, patching may or may not be required, and updating diagrams is less important than ensuring the dependencies are understood and met.
