DMAIC model – why to use it

It is hackneyed phrase to say, that people are trying to be better and live better every day. But truth is, that improvements are engine for earning more money, better living, working safer…

To earn more, you need to build some of your skills isn´t it? To decrease some heavy work from 40 to 5 minutes or to zero you need to do something about it. Or get food in 10 minutes after order instead of 30? Some change needs to happen. There are tons of great examples in this word, that are evidence that improvement is possible and it worth it.

And the ones, who are able to deliver faster, can do something cheaper are winners.

What is DMAIC process?

DMAIC is a core method to drive six sigma projects. I know people that will have nettle-rash just by pronouncing “project” word :D. Yeah, sometimes project leaders do not do very good job, by jumping to fast and not very efficient solutions. This ruins projects reputation.
Project, how I see it, is an activity to deliver good change or positive results – called improvement.

Launch path for positive changes is understanding current situation deeply. And then proven method to improve.

Take Six Sigma method as an umbrella covering different toolboxes, that allows us to react on different opportunity types.

  • DMAIC – to improve existing
  • DMEDI – to create not existing
  • PDCA – to sustain and develop running

Let’s focus on DMAIC in this article.

DMAIC is a method, that helps to improve current existing processes, we are not satisfied with their performance.

DMAIC is an acronym that stands for: Define, Measure, Analyze, Improve and Control. These are five phases followed during the project life cycle. Every phase requires some steps to be accomplished. To make sure, team is following the right path, that will lead to the ultimate project goal.
