DMAIC is an acronym that represents the step-by-step process of the Six Sigma methodology for improving processes and achieving higher quality outputs.
Each DMAIC phase has specific goals and tasks:
- Define – In this phase, process improvement goals are defined, customer requirements and expectations are identified, team members are selected, and project scope is established.
- Measure – In this phase, data is collected about the process and its outputs, process performance is measured, key performance indicators (KPIs) are identified and a baseline performance level is established.
- Analyze – In this phase, the collected data is analyzed and the causes of problems that prevent the process from achieving its goals are identified. Various statistical tools are used to identify correlations and connections between data.
- Improve – In this phase, measures to improve the process identified in the previous phases are developed and implemented. These measures are tested and verified to ensure they are effective and feasible.
- Control – This phase ensures that the improvements have been successful and sustained. Control mechanisms are designed and implemented to monitor the process and ensure that improved performance levels are maintained.
DMAIC proceeds in a linear fashion, with each phase building on the results and findings of the previous phase. Six Sigma Black Belt certification focuses on providing the specialized knowledge and skills needed to properly use the DMAIC methodology and successfully improve processes in an organization.
