This document provides a roadmap for the control phase of the DMAIC process for process improvement. It begins with differentiating between the two types of variation: common cause variation and special cause variation. Common cause variation is normal, inherent to the system, and results from random factors. Special cause variation is abnormal, results from assignable causes, and makes the process unpredictable. The document then lists some learning objectives related to variation before providing healthcare examples of variations.
