How to Improve: Model for Improvement
IHI uses the Model for Improvement as the framework to guide and accelerate improvement work.
The Model for Improvement,* developed by Associates in Process Improvement, is a simple yet powerful framework for accelerating improvement.
The model is compatible with any change models that organizations may already be using and can help to accelerate improvement.
The Model for Improvement has two parts:
- Three fundamental questions, which can be addressed in any order.
- The Plan-Do-Study-Act (PDSA) cycle** to test and adapt changes to ensure they result in the desired improvement.
The three fundamental questions in the Model for improvement can be addressed in any order, although teams typically start with the first question — What are we trying to accomplish? — to guide them in setting aims.
Answering the model’s three questions is an iterative process — the team moves back and forth between them as changes in thinking in one question or learning from PDSA cycles results in changes in thinking in another.
The Model for Improvement has been used successfully in many industries, including thousands of health care organizations in numerous countries to improve countless different processes and outcomes. The model can also be used to ensure that improvements result in closing equity gaps rather than maintaining or widening them by applying an equity lens at every step of the process.
