In applying PDSA, you ask 3 questions:
1. What is our goal (i.e. what are we trying to accomplish)?
2. What change can we make that will result in improvement?
3. How will we know the change is an improvement?
In the preparation stage, you answer the first question: What is our goal? You will define the focus of your PDSA project using the charter and goal setting tools. You will also gather an effective team to test changes using the PDSA model.
