QI 101 Lesson 3: Changing Systems with the Science of Improvement
In this lesson, you’ll learn why improvement, especially in a complex environment such as health care, requires us to think about the larger systems in which we live and work. You’ll learn about two famous engineers, W. Edwards Deming and Walter A. Shewhart, who developed theories and tools to help improvers better visualize and understand the interdependent components of a system. Finally, you'll practice applying Deming's four-part framework for improvement, the System of Profound Knowledge.
