The Quality Improvement Journey

Why Testing Changes is important

All improvement requires change but not every change results in improvement.

The outcomes that teams achieve are a result of how their systems work including how they help people to do the right thing. To get different, improved outcomes we need to identify and develop specific ways to change the system. These ideas should then be tested to find out what works.
