What is the BEST description of the CSI register?

Authorized changes and their planned implementation dates are tracked in the change schedule (forward schedule of change), which belongs to Change Management, not the CSI register.

The CSI register is a forward-looking document maintained by the Continual Service Improvement process to capture proposed improvement opportunities along with their anticipated benefits, priority, and business justification. It is not a record of completed work but a pipeline of ideas under consideration or in progress. This distinguishes it from historical reports or operational logs.

New services awaiting customer approval are managed through the service portfolio and service catalog, not the CSI register, which is scoped to improvement opportunities rather than new service requests.

The CSI register captures proposed improvements, not completed ones - completed improvement outcomes are reported via CSI reports and metrics dashboards, not the register itself.
