Define, Measure, Analyse, Improve, Control (DMAIC)     Print

DMAIC is used for projects aimed at improving an existing business process.  DMAIC has been defined as a metric measurement of defects, as a methodology, and as a business management strategy used for existing business processes. Together with DMADV, it is one of two key methods used to implement Six Sigma.

DMAIC is an acronym for a five-step improvement process: Define, Measure, Analyse, Improve, Control.

  • Define: Define the problem, the process, and the project goals. In Six Sigma it is imperative that the problem is specifically defined. Alluding to slowing business is a poorly defined problem. Instead, the problem should be clearly established in quantitative terms. So a good Six Sigma problem definition would be a 35% decrease of net sales in the past two consecutive quarters.
  • Measure: Measure and collect data that will determine the factors that have influence over the outcome of the process or procedure.
  • Analyse: The data is analysed using statistical tools to assess whether the problem is real or random, which makes it unsolvable within the Six Sigma framework.
  • Improve: If the problem is real, the Six Sigma team identifies solutions to improve the process based on the data analysis.
  • Control: Control planning, including data collection and control mechanisms, is required to ensure that the solutions can be sustained to deliver peak performance and early deviations from the target do not materialize into process defects.
