QI 102 Lesson 5: Testing Changes
By testing changes on a small scale and tracking your results as you go, you can see how your changes are affecting the process you're trying to improve. The testing phase in the Model for Improvement, developed by the Associates in Process Improvement, is what we call PDSA (Plan-Do-Study-Act). PDSA cycles allow you to conduct rapid tests of change, to grow your learning quickly while minimizing the risk of introducing a change in a complex system.
