You have just told your mother one sentence about your private life problems and now she is already talking for 1 hour proposing to you manifold solutions… Very good solutions!!! The only shortcoming: These solutions will not solve your problem. Simply train your mum in DMAIC and you won’t be in this situation again!



The DMAIC methodology originated in Six Sigma, however it can be applied on all kinds of improvement projects and in problem solving. It also provides project management guidance for such projects.

Following the 5 phases of DMAIC helps to identify the root cause(s) of a problem and to ensure sustainable success.


  • DMAIC prevents “jumping to a solution” without making sure having found a sustainable solution for this problem.
  • DMAIC gives orientation in complex situations
  • DMAIC helps also beginners to work with appropriate tools to solve problems or to improve a process

The DMAIC roadmap provides step-by-step guidance through a process improvement project with the tools you need.



  • Define the problem to solve. Make a clear problem statement. Define by which metrics you can measure your problem or how you can measure your improvement. This is your Y. Set goals. Calculate your business case to figure it is worth to solve this problem.
  • Measure the extent of the problem. Measure your Y. Identify potential root causes. These are your Xs. Which data is lacking to prove root cause effect relations? This drives your Data Collection Plan.  
  • Analyze root cause effect relations of your problem or improvement initiative. Can you prove one? In Analyze you make sure that the solution you will be implementing will solve the problem. You might need additional measurements for this.
  • Improve by finding and implementing solutions.
  • Control success. Did you achieve goals? Measure Y and compare results to your goals set-up in Define. Hand-over what you have implemented to someone who will keep measuring the Y. Often much less data will be required than you needed during your DMAIC project.
