Plan-Do-Study-Act (PDSA)
Plan-Do-Study-Act (PDSA), also known as the Deming Cycle, is a systematic series of steps for gaining valuable learning and knowledge for the continual improvement of a product or process. Pronounced as /plan-doo-stuh-dee-akt/.
Etymology
The term "Plan-Do-Study-Act" was coined by W. Edwards Deming, a statistician, professor, author, lecturer, and consultant. The cycle is also known as the Deming Cycle or Shewhart Cycle, named after Walter A. Shewhart, who is considered the father of statistical quality control.
Definition
The PDSA cycle is a four-step model for carrying out change. The steps are:
- Plan: Identify an opportunity and plan for change.
- Do: Implement the change on a small scale.
- Study: Use data to analyze the results of the change and determine whether it made a difference.
- Act: If the change was successful, implement it on a wider scale and continuously assess your results. If the change did not work, begin the cycle again.
