IT Best Practices With ITIL: Page 7 of 7

Step 1 calls for containing firefighting by severely limiting access and change. This reduces the number of unplanned, unknown changes and shortens diagnostic time during failures.

In Step 2, you take inventory. That means finding out what's out there in software, hardware and applications, then determining which of your failed systems will really be a pain to get running again--for example, the server set up two years ago by the consultant who's moved to Bolivia.

Step 3 entails creating a repeatable configuration for all IT assets. It also includes managed change and release management so the repeatable configuration images remain accurate.

In Step 4, you develop a process for continuously refining this change and release management. The object is to get IT planning and designing on the front end of change so you can avoid problems altogether.
