This video delves into the Study and Act steps of the Plan-Do-Study-Act (PDSA) cycle, focusing on how to surface learning from the test of a change idea to guide decisions about next steps. It also discusses how to plan for iterative testing cycles to refine a change idea and build evidence for a theory of improvement.
This is the fourth video in a five-part series focused on deepening improvers’ knowledge of and skills in conducting PDSA cycles to test and refine change ideas designed to improve specific outcomes.
During this video, the presenter discusses key considerations to attend to during the Study step of the PDSA cycle, emphasizing the importance of analyzing data, revisiting predictions, and surfacing assumptions when reflecting on a test individually or with a group. This evidence and reflection informs the decision during the Act step to adopt, adapt or abandon a change idea.
Additionally, the video shares an example of how iterative testing (multiple PDSA cycles that build on each other) can be leveraged to refine a change idea over time and generate evidence to show whether the change is leading to the desired system outcomes.
