What is a Configuration Item (CI)?

A Configuration Item (CI) is defined as any component that needs to be managed in order to deliver an IT service. This includes not only hardware and software but also documentation, processes, and any other resources necessary for ensuring that services are delivered effectively and efficiently.

The identification and management of CIs are fundamental to maintaining control over the IT environment, as they provide a structured way to manage assets and resources that affect service delivery. Knowing what CIs exist, their relationships, configurations, and their statuses helps organizations maintain service quality, facilitate change management, and respond to incidents more effectively.

Understanding CIs within the context of ITIL is essential as it underpins various practices, including change management and incident management. A comprehensive and accurate Configuration Management Database (CMDB) ensures that organizations have visibility into their components, which is vital for effective service management.
