This was done at Department of Diagnostic Radiology, Henry Ford Hospital,
2799 W Grand Blvd, Detroit, MI.
It is more complex than most I would expect, and the team did not quit, they followed through their learning.
I've been implementing Lean for 10 years, part of that in healthcare, if you have questions or a hospital CEO interested in leading your facility to obtain these results.
It works.
The question is are you learning how to apply it Alberta Health Services?
