ITIL Service Asset and Configuration Management: Process Definition
Activities and process objectives of the Service Asset and Configuration Management process are broadly identical in ITIL V3 and V2. ITIL V3 introduces the "Configuration Management System (CMS)" as a logical data model, encompassing several Configuration Management Databases (CMDB).
The following sub-processes are part of Service Asset and Configuration Management:
Sub-Processes
- Configuration Management Support
- Process Objective: To define and update the CMS structure in such a way that it can hold the required information related to CIs, including their attributes and relationships.
- Configuration Verification and Audit
- Process Objective: To perform regular checks, ensuring that the information contained in the CMS is an exact representation of the CIs actually installed in the live production environment.

ITIL Terms: Service Asset and Configuration Management
- Change Request to CMS Structure
- A request from a Service Management process to change the CMS structure. This request is sent to Configuration Management if new CIs or attributes must be recorded but the CMS's structure is not adequate for holding the new data.
- CMS/ CMDB
- The Configuration Management System (CMS) is a coherent logical model of the IT organization’s infrastructure, typically made up of several Configuration Management Databases (CMDBs) as physical sub-systems. It is used to store information on all Configuration Items (CIs) under the control of Configuration Management (see also: ITIL Checklist CMS - CMDB).
- CMS Change Policy
- A set of rules defining who is authorized to modify the structure and contents of the CMS.
- Configuration Audit Report
- A report summarizing the results of a CMS audit, highlighting revealed differences between CMS records and actually installed CIs.
- Definitive Media Library (DML)
- One or more locations in which the definitive and approved versions of all software Configuration Items are securely stored. The DML may also contain associated CIs such as licenses and documentation.
- DML is a single logical storage area even if there are multiple locations. All software in the DML is under the control of Change and Release Management and is recorded in the Configuration Management System. Only software from the DML is acceptable for use in a Release.
