FREE COURSE: Variation

Process variation is an important concept in continuous process improvement. Distinguishing between common-cause and special-cause variation is key to understanding the responding to signals from the data.


All natural processes exhibit variation–it is not possible to eliminate process variation.  However, understanding the sources of the variation we see in these processes allows a team to craft a response that ensures continued stability and sets the stage for continuous improvement.  This lesson is devoted to understanding variation–what are the causes of variation, which types of variation characterize healthcare processes, and how can we use this information to optimize our response when we detect the potential for process instability.
