People are drawn to IT by a fascination with complex technology. This is most unfortunate because this fascination blinds so many of us to the importance of the People/Process/Product trilogy.
Change and Configuration Management are processes. If the process is working, they collect and maintain good configration data (in a repository that you can call a CMDB if you insist). If the process is broken technology is not going to fix it. Bang your head hard against the desk while repeating five times "technology is not going to fix it".
