The PDSA (Plan-Do-Study-Act) Cycle is a widely used iterative method for implementing change and improving processes. It's a fundamental concept in quality management and continuous improvement. The cycle involves four key stages:
- Plan: Identify a goal or purpose, create a plan to achieve it, and define the metrics for success. This stage involves understanding the problem, setting objectives, and developing a hypothesis on how changes will lead to improvement.
- Do: Implement the plan on a small scale to test the change. This phase involves carrying out the plan and collecting data to measure the impact of the changes.
- Study: Analyze the data collected during the "Do" phase to assess whether the changes made led to improvement. Compare the outcomes against the expected results and determine if the hypothesis was correct.
- Act: Based on the findings from the "Study" phase, decide whether to adopt, adapt, or abandon the changes. If successful, implement the change on a larger scale; if not, refine the plan and start the cycle again.
The PDSA Cycle is also known as the Deming Cycle, named after W. Edwards Deming, a key figure in the development of modern quality management practices.
