The PDCA cycle is the four-stage iterative methodology underpinning continual improvement in all ISO management systems.
The PDCA cycle (Plan-Do-Check-Act), also known as the Deming cycle, is the conceptual framework structuring continual improvement in ISO standards. Plan establishes objectives and processes; Do implements what was planned; Check monitors and measures results; Act takes actions to improve performance.
It was developed by Walter Shewhart and popularized by W. Edwards Deming. That is why it is also known as the Deming cycle.
No. Annex SL integrates it into all ISO management system standards: information security, continuity, environment, AI, anti-bribery, etc.
