1.1 Plan, Do, Study, Act (PDSA) - every improvement is an experiment


  • PDSA is a very good way to think about improvement and is a key tool in any improvement work.  
  • PDSA provides a framework for developing, testing and implementing change that may lead to improvement.  
  • PDSA can be used to test out any planned improvement or change in the way we work on a small scale, in small steps.



The change to be implemented


Carry out the change


Based on the measurable outcomes agreed before starting out, collect data before and after the change and reflect on the impact of the change and what was learned


Scale up or standardise the improvement or plan the next PDSA cycle
