Which part of the PDCA cycle is concerned with monitoring and evaluating processes?

The part of the PDCA cycle that focuses on monitoring and evaluating processes is “Check.” In this phase, organizations assess and analyze their processes to determine if they are operating as intended and are achieving their objectives. This involves collecting data, measuring performance against established metrics, and identifying any areas of improvement or non-conformance.

During the Check phase, auditors and stakeholders review the effectiveness of what was implemented in the "Do" phase, ensuring that processes align with the planned objectives set in the "Plan" phase. This evaluation helps in understanding whether the actions taken led to the desired outcomes, which is crucial for continuous improvement within the information security management system.

In contrast, the Plan phase is about establishing objectives and policies, the Do phase is about implementing those plans, and the Act phase involves making adjustments based on the evaluations conducted in the Check phase. Each phase builds upon the others, but the primary role of Check is centered around assessment and evaluation.
