DMAIC refers to a data-driven quality strategy for improving processes, and is an integral part of the company’s Six Sigma Quality Initiative. DMAIC is an acronym for five interconnected phases: Define, Measure, Analyze, Improve, and Control.
Each step in the cyclical DMAIC Process is required to ensure the best possible results. The process steps:

- Define project boundaries ¬≠ the stop and start of the process
- Define the process to be improved by mapping the process flow
Measure¬†the performance of the Core Business Process involved.
- Develop a data collection plan for the process
- Collect data from many sources to determine types of defects and metrics
- Compare to customer survey results to determine shortfall
Analyze¬†the data collected and process map to determine root causes of defects and opportunities for improvement.
- Identify gaps between current performance and goal performance
- Prioritize opportunities to improve
- Identify sources of variation
Improve the target process by designing creative solutions to fix and prevent problems.
- Create innovate solutions using technology and discipline
- Develop and deploy implementation plan
Control¬†the improvements to keep the process on the new course.
- Prevent reverting back to the “old way”
- Require the development, documentation and implementation of an ongoing monitoring plan
