Defining Service Components and Configuration Items

A configuration item is any component that must be controlled in order to deliver or manage a service. Rather than recording everything possible, the useful scope of configuration items should be set by the decisions they support and the risks they help manage.

• Start from service decisions and impact needs. Configuration information is a decision asset, so its scope and detail should be justified by the incident, change, risk and service questions it helps people answer.
• Choose appropriate item types and attributes, and define relationships. In the article's example, a team records the application, a key integration and the accountable owner because those relationships support incident and change decisions.
• Assign data ownership. Every set of configuration data needs a named owner, and data ownership coverage is one of the measures worth tracking, alongside decision use of configuration data and relationship completeness.
• Avoid three common pitfalls. Recording everything possible creates effort without value, treating asset and configuration as synonyms blurs what needs control, and creating detail with no consumer produces data nobody uses. Test the practice against a real service scenario before making it standard, and review results with delivery teams and affected consumers, because operational success and experienced value can diverge.
