The Analyze Phase is the third phase of the DMAIC process, and focuses on identifying the root cause (or causes) of a process problem.

The Analyze Phase requires data and knowledge gleaned from the previous Define and Measure phases of DMAIC. This phase focuses on analysis of the data and the process. In terms of the data focus, statistical analysis is a cornerstone of Analyze, ensuring that potential root causes are not only validated but significant enough to merit attention. Methods and tools used include Process Maps, Charts and Graphs, Hypothesis Testing, and Value-Added Analysis.
