Guided by simple but effective improvement principles, the Model for Improvement helps us deliver results-based outcomes and support improvement in healthcare and public sector agencies in Victoria.

The below Model for Improvement graphic was developed by the Institute for Healthcare Improvement.

Using the model

The model asks three questions to guide improvement:

  1. What are we trying to accomplish?
  2. How will we know that a change is an improvement?
  3. What changes can we make that will result in improvement?

Answering these three questions will help you understand the problem you are trying to solve. You can then develop your ideas for change.

These ideas can be tested through small scale Plan-Do-Study-Act (PDSA) cycles to determine how effective the changes are towards your improvement goal.


The PDSA cycle helps you test and refine your change ideas by asking you to:


Develop a plan to test the change.


Carry out the test.


Observe and learn from the consequences.


Make modifications to the test.
