  • Do: Implement the plan on a small scale (a pilot or trial) to test its effectiveness.

  • Check: Analyse the results and gather data to assess whether the plan achieved the desired outcomes.

  • Act: Based on the assessment, make necessary adjustments and standardise the improved process.

PDSA (Plan-Do-Study-Act): This cycle is quite similar but places a stronger emphasis on studying and learning from the results:

  • Plan: Like PDCA, you plan the improvement, set goals and outline the process changes.

  • Do: Implement the plan as a small-scale trial, just as in PDCA.

  • Study: This step involves a more in-depth analysis of the results, looking for trends, patterns and root causes of any issues.

  • Act: Based on the study phase, make informed decisions about whether to standardise the changes, revise the plan, or take further actions for improvement.

Both PDCA and PDSA are iterative cycles designed to drive continuous improvement. The main difference is in the "Check" phase of PDCA, which focuses on assessing outcomes, while the "Study" phase of PDSA involves deeper analysis to gain a better understanding of the process. Choosing between them depends on the specific needs and goals of your improvement project, with PDSA often preferred when a more thorough understanding of the underlying factors is required.
