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 and how you might revise them for better results. This lesson will explain the reasoning behind the Plan-Do-Study-Act (PDSA) cycle and demonstrate how it’s used to test changes sequentially. In this lesson, you will also conduct the first testing cycle of your own improvement project.
