Run a Guided PDSA - Do (Collect Data, View Data, Observations)

A PDSA cycle is the basic method of inquiry in improvement research. It’s a pragmatic scientific method for iterative testing of changes in complex systems. Each cycle (Plan-Do-Study-Act) is a mini-experiment in which observed outcomes are compared to predictions. Discrepancies between predictions and observed outcomes become a source of learning.

To Do a guided PDSA, enter data from within an In Progress guided PDSA displayed on the Homepage.


On the incomplete PDSA’s summary page, select Edit to continue your test.


In response to each PSDA Question on the Do page, add quantitative data, qualitative data, or both. Add attachments by selecting Attach Data File, add time-stamped data with the Quantity and Unit fields, enter Observations about what happened when you tested the change idea, and Run Chart your quantitative data.

  • Tip for Collecting Data: Describe what happened during the test, especially if it differed from your plan. Also, describe anything that was unexpected, difficulties you had with the test or data collection, or general observations you have about what happened during the test.


Do not upload any Personally Identifiable Information (PII).

If you are ready to proceed, select the Next: Study button to continue with the PDSA cycle.
