The Model for Improvement developed by Associates in Process Improvement (API) is the most well-known model for providing a simple, yet effective tool for accelerating improvement in small through to large organisations.
It starts with the questions:
- What are we trying to accomplish?
- How will we know that a change is an improvement?
- What changes can we make that will result in an improvement?

PDSA cycles
Plan, Do Study, Act (PDSA) cycles are then used to test each idea, test a small change, study what worked, what didn't, act on the changes that are needed, then plan the next PDSA to test.
