What change-management document outlines the processes that will take place if you decide not to move forward with a project that modifies your network at a critical go/no-go point?

Every time you plan to alter a business system, you must also have a backup plan in case things don't go as planned and you need to revert to the previous configuration.  A rollback plan refers to a strategy for returning to the old system. Before making modifications, sandbox testing is done to make sure they will work. At the start of the change management process, request forms are completed, and a risk analysis determines whether to move forward with the change.
