In ITIL 4, the continual improvement practice uses a continual improvement register (CIR) as a key tool to record, prioritize, track, and manage improvement opportunities.
The CIR is used to:
Log improvement ideas from any source
Track these ideas from initial identification through assessment, prioritization, and implementation
Provide visibility of the status and progress of each improvement
Support decision-making about which improvements to pursue and when
This matches option C: “Used to track and manage improvement ideas from identification through to final action.”
Why the other options are incorrect:
A. Used to help plan changes, assist in communication, avoid conflicts, and assign resourcesThis describes aspects of change enablement and change schedule / change calendar, not the continual improvement register.
B. Used to select the right method, model or technique for identifying improvementsMethods and models (such as SWOT, balanced scorecard, etc.) support improvement activities, but the CIR is not about choosing methods; it is about recording and managing improvement opportunities.
D. Used to provide a formal description of one or more services, designed to address the needs of a target consumer groupThis describes a service catalogue entry or service offering, not a continual improvement register.
So, the CIR is specifically a tracking and management tool for improvement ideas, making C the correct answer.
