What does it mean when a change is in the 'Closed' state?

When a change is in the 'Closed' state, it signifies that the change has been successfully implemented and assessed. This state indicates that all necessary activity related to the change has been completed, including ensuring that the change is functioning as intended and that any impacts on the services provided have been reviewed.

Once a change reaches the 'Closed' status, it often means that any follow-up actions, such as documenting lessons learned, have also been taken care of. This stage is critical in IT Service Management, as it contributes to the end-to-end lifecycle management of changes, ensuring that changes lead to improvements in service delivery and can be referenced in the future to prevent similar issues or make further enhancements.

In contrast, other states like being in documentation, under review, or canceled represent stages where the change has not yet been fully executed or concluded, which is why they do not reflect the complete cycle that is inherent in reaching the 'Closed' status.
