Jump to: navigation, search

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. DMAIC is an incremental process improvement using the Six Sigma methodology.

Each step in the cyclical DMAIC Process is required to ensure the best possible results. The process steps:

Define

  1. Define the Customer, their Critical to Quality (CTQ) issues, and the Core Business Process involved.Define who customers are, what their requirements are for products and services, and what their expectations are.
  1. Define project boundaries ­ (the beginning and the end of the process).
  2. Define the process to be improved by mapping the process flow.

Measure the performance of the Core Business Process involved.

  1. Develop a data collection plan for the process.
  2. Collect data from many sources to determine types of defects and metrics.
  3. 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.

  1. Identify gaps between current performance and goal performance.
  2. Prioritize opportunities to improve.
  3. Identify sources of variation.

Improve the target process by designing creative solutions to fix and prevent problems.

  1. Create innovate solutions using technology and discipline.
  2. Develop and deploy implementation plan.

Control the improvements to keep the process on the new course.

  1. Prevent reverting back to the "old way".
  2. Require the development, documentation and implementation of an ongoing monitoring plan.
  3. Institutionalize the improvements through the modification of systems and structures (staffing, training, incentives).
