CMBD: crucial component of the ITIL architecture

CMDB design and its implementations are tricky stages when implementing ITIL.

CMDB (Configuration Management DataBase) is usually associated to change management and configuration management processes.

A CMBD really brings value to IS and business process. It is a repository of information related to all the components of an information system.

Information in the CMDB is called CI (Configuration Items). These are composed of basic units of configuration management and change management.

Configuration Items subdivide the system components into identifiable subgroups. They can be made up of equipment, resource use, users, services, software, business applications …

A CMBD’s main goal is to help manage the complexity of a IS by having the IT infrastructure focussed on business services.

A CMBD also helps identify and control dependencies between the CI and the services.

Therefore, the CMDB analysis helps the decision-making process when required and allows change optimisation for the best possible business gains.

The goal of the CMDB is twofold:

• ROI maximisation and advantages of ITIL
• Optimisation of the information system business value

CMDB’s success factors

• Determine the objectives before the means
• Motivate the users and train the contributors
• Domain analysis
• Step-by-step advances
• Automation – as much as possible
• Dedicate enough resources to the project
• Involve top management
• Manage project implementation
• Open to all and CMDB simplification
• Getting support
