With an accurate CMDB, the source of the incident can be isolated quickly, and then details about the failing component, such as software and ﬁrmware levels, can be viewed. Having conﬁguration data in place can literally cut hours off the time it takes to resolve a complex incident. The CMDB—or more speciﬁcally, the information it contains—is equally important to change management. A change review board might be reviewing tens or even hundreds of potential changes in a meeting. On the surface it might look like approving two changes for two separate business applications would be unrelated tasks, and both might get approved.
On the surface it might look like approving two changes for two separate business applications would be unrelated tasks, and both might get approved. By looking at an accurate CMDB, however, the change board can quickly see that both applications depend on the same database server, and one change record has asked to have the server backed up while the other change record has asked to have the same database server taken out of service. Clearly both changes cannot be implemented at the same time; but without conﬁguration management data, these conﬂicts can be all too common.
But just like the change from the old indexed databases to the more modern relational schemes, using relationships to describe an environment requires new techniques and thought processes. You will ﬁnd much in this book to help you make that shift in the way your organization thinks. The third milestone along the conﬁguration management journey is one in which the organization ﬁnds itself maturing and perhaps even reengineering its processes. Accurate conﬁguration data, including relationships, will help align other IT processes with the industry best practices which ITIL represents.
