What is Unified Change Management (UCM), and how does it apply to IBM® Rational® ClearCase?
UCM was developed to make it much easier for people using ClearCase to get started with an effective use model. This is because a “base” ClearCase installation has so much flexibility that many organizations find it difficult to use the application out of the box. To make ClearCase more useful to their specific needs, they write their own scripts and processes. UCM was an effort to identify the most common elements of ClearCase use models, and to create objects and methods that make the application more effective. If you are currently running the base install of ClearCase, you may at some point consider an upgrade to UCM. But where to start? What is involved? What are the differences? Before considering a move from your current ClearCase system to a UCM system, you should first understand your current use model — and how your organization has been using the Basic ClearCase objects since your installation. This process of change is very much like moving to ClearCase for the first time.
