What is the purpose of the Analyze phase in DMAIC?

• A. To develop solutions for identified problems
• B. To identify root causes of defects
• C. To establish a high-level overview of a process
• D. To ensure improvements are sustained over time

Answer: (B)

The purpose of the Analyze phase in DMAIC (Define, Measure, Analyze, Improve, Control) is to identify the root causes of defects. At this stage of the process improvement methodology, teams focus on understanding why the problems identified in the Measure phase are occurring. This involves examining collected data to identify patterns, relationships, and underlying problems that contribute to defects or inefficiencies. During the Analyze phase, techniques such as root cause analysis, cause-and-effect diagrams, and other statistical tools are often employed to dig deeper into data and understand the contributing factors that lead to defects. This thorough investigation is essential, as understanding root causes facilitates the development of effective solutions in the subsequent Improve phase. By pinpointing these root causes, teams ensure that the solutions implemented will address the real issues rather than merely treating symptoms. The other options, while related to different phases of the DMAIC process, do not accurately represent the specific objective of the Analyze phase. Developing solutions pertains to the Improve phase, establishing a process overview relates to the Define phase, and ensuring sustained improvements falls under the Control phase.
