The model for improvement is a simple framework for accelerating improvement.
The model for improvement is a simple framework for accelerating improvement. The model has two key components:
Together, the three questions and the PDSA cycle create a framework for continuous improvement.
An improvement team would use the tool as a framework for applying the five fundamental principles of improvement:
The Model for Improvement starts with three questions. These help an improvement team understand what they want to achieve, how they will measure success and what changes they should test. This is sometimes referred to as the "thinking" part of the model.
1. What are we trying to accomplish?
Having identified an opportunity for improvement, the team should develop an aim statement that clearly describes what they want to achieve. An effective aim statement should be:

2. How will we know that a change is an improvement?
Teams should identify a family of measures that will help them understand whether their changes are leading to improvement. These are grouped into:
Together, these measures help teams understand the impact of their work.
3. What changes can we make that will result in improvement?
Improvement is most effective when teams work together to understand the system and generate ideas for change. A variety of tools can help with this, including:
We would also recommend the development of a driver diagram to organise and communicate the theory of change.
Using PDSA cycles to test change
Once a team has identified a change idea, they can use a Plan-Do-Study-Act (PDSA) cycle to test it. This is sometimes referred to as the "doing" part of the model.
By starting small, learning from each test and building on what works, teams can reduce risk and increase confidence that changes will lead to improvement.
