Like many other quality management systems, ISO 45001 uses what is known as a 'PDCA'...

The PDCA (Plan-Do-Check-Act) model is a continuous improvement framework used in ISO 45001 and other management systems.

Plan: Establish objectives and processes to deliver results in line with the OH&S policy.

Do: Implement the processes.

Check: Monitor and measure processes against the policy, objectives, and requirements.

Act: Take actions to continually improve the system's performance.

Analysis of Options:

A. Plan, Do, Check, Act:Correct. This is the standard PDCA cycle.

B. Plan, Do, Check, Ask:Incorrect. "Ask" is not part of the cycle.

C. Plan, Deliver, Control, Achieve:Incorrect. This is not the PDCA cycle.

D. Prepare, Deliver, Control, Assess:Incorrect. This deviates from the PDCA framework.
