The concept of the Configuration Management Database (CMDB) is not exceedingly difficult to comprehend, particularly as it applies to the Information Technology Infrastructure Library (ITIL).
However, the actual implementation of a CMDB and clearly demonstrating value can introduce subtle complexities as a result of competing business objectives and internal IT requirements.
But as a standard and trusted data source, even the simplest of CMDBs can provide a means for improving internal communications and dialogue with IT customers. Even small-scale CMDB deployments could potentially help IT yield measurable benefits in operational effectiveness, cost efficiencies and improve the overall quality of service.
