Which of these is managed under the control of change management?

Change management primarily focuses on the process of overseeing changes to configuration items (CIs) within an organization's IT infrastructure. This includes the planning, tracking, and implementation of changes to ensure that they are made in a controlled manner, minimizing potential disruptions to services. The management of CIs involves understanding their components, relationships, and the impact that changes could have on overall service delivery and quality.

By controlling changes to these CIs, change management helps to ensure that any alterations are documented, reviewed for risk assessment, and communicated effectively across the organization. This is critical for maintaining the integrity of the IT services and ensuring that they remain aligned with business objectives.

The focus on CIs is essential because every change made to a CI could affect the configuration and functioning of other elements within the IT environment. Properly managed change leads to improved reliability and availability of IT services, which is a fundamental goal of change management within the ITIL framework.
