Is there research related to the impact of QM, and, if so, what does it say?

A good place to get a snapshot of research on the impact of QM is the QM Impact Summary. This summary gives the context in which research has been (and should be) done on QM along with a few brief examples of the impact of QM professional development and course reviews. In addition, take a look at the QM Research Resources, including studies on QM impact, publications and presentations on QM programs and services, and publications on the QM grant initiative.
