DMAIC

Define, measure, analyze, improve, and control (DMAIC) is a data-driven quality strategy used to improve processes.

• Define the problem, improvement activity, opportunity for improvement, the project goals, and customer (internal and external) requirements.
• Measure process performance.
• Analyze the process to determine root causes of variation and poor performance (defects).
• Improve process performance by addressing and eliminating the root causes.
• Control the improved process and future process performance.
