The Act phase of PDCA cycle consists of improvement?

The Act phase of the PDCA cycle consists of improvement. The Act phase is the fourth and final phase of the PDCA cycle, following the Check phase. In the Act phase, the organization takes action based on what it learned from the Check phase, where it monitored and evaluated the results of the Do phase, where it implemented the plan developed in the Plan phase. The action can be one of the following options1:

If the change was successful, the organization can standardize and stabilize the change, and communicate and document the results and the lessons learned. The organization can also identify opportunities for further improvement and start a new PDCA cycle with a different plan.

If the change was not successful, the organization can identify the root causes of the failure and revise the plan accordingly. The organization can also start a new PDCA cycle with the revised plan or a different plan. The Act phase is the phase where the organization improves its processes and performance by incorporating the learning from the previous phases. The Act phase also helps the organization to sustain the improvement and prevent the recurrence ofproblems. The Act phase is aligned with the clause 10 of ISO 22301, the international standard for business continuity management systems, which requires the organization to improve its business continuity management system by taking corrective actions, addressing nonconformities, and enhancing customer satisfaction2. References:
