Project targets or goal

Project boundaries or scope


Identify the gap between current and required performance.

Collect data to create a process performance capability baseline for the project metric.

Assess the measurement system for adequate accuracy and precision.

Establish a high level process flow baseline.


List and prioritize potential causes of the problem

Prioritize the root causes to pursue in the Improve step

Identify how the process inputs (Xs) affect the process outputs (Ys).

Help pin-point where in the process the root causes reside, and what might be contributing to the occurrence.


Create innovative solutions

Focus on the simplest and easiest solutions

Test solutions using Plan-Do-Check-Act cycle

Using FMEA to anticipate any avoidable risks associated with the "improvement"

Create a detailed implementation plan


Monitor the improvements to ensure continued and sustainable success.

The DMAIC methodology diagram can be created online or offline using free templates. A DMAIC model is a roadmap for Six Sigma, used to improve the quality of results that company processes produce. The letters DMAIC are short for: Define, Measure, Analyze, Improve, and Control. These five parts are filled in by following several steps: the defined phase where the user has to describe the problems that need to be solved and the weight the situation has for the organization or business. The measure phase is to define the defect and collect baseline information regarding the performance of the product or process. The Analyze phase is to determine which parameters have the most effect on the critical process results. The improvement phase is there to identify opportunities for improvement, substantiated with information on the way these improvements help achieve the project goals. The control phase is there to implement the chosen solutions and make sure these are ingrained in the organizational process.
