Service management system continual improvement
This domain covers Clause 10: nonconformity and corrective action, and continual improvement. The exam tests the difference between fixing a symptom and improving the SMS, and whether improvement is planned, evidenced and verified.
Corrective action
When a nonconformity occurs, the organization reacts to control and correct it, deals with consequences, and evaluates the need to eliminate the cause so it does not recur. It implements action, reviews effectiveness, updates risks and opportunities, and makes changes to the SMS if needed. Documented information is retained as evidence of the nonconformity, actions taken and results.
Continual improvement
Continual improvement is ongoing. The organization determines and selects opportunities, based on analysis and evaluation, management review, audit results, performance trends and objectives. It plans and implements actions to improve services, processes and the SMS, and evaluates results. Improvement can be incremental or transformative, but it must be linked to intended outcomes and customer requirements.
Worked example
Repeated failures occur because monitoring certificates expire. The team renews the certificate and closes the ticket. That is correction, not corrective action. Corrective action asks why expiry was not detected, adds an owned renewal calendar and alert, updates the risk assessment, and checks later that expiries no longer cause incidents. The verification step is what makes it a management system improvement.
Traps
Do not treat correction as corrective action. Do not close a nonconformity without root-cause analysis and effectiveness review. Do not limit improvement to large projects. Do not ignore improvement opportunities from reviews and audits. Do not leave documented information or risk updates incomplete.
