Now is that not just common sense? This is a critical phase in which the team outlines the project focus for themselves and the leadership of the organization. DMAIC is a five-step method for improving existing process problems with unknown causes. Let us look at a car garage with 50 locations who specialise in car tyres as an example. With this understanding, what remains for those learning Six Sigma are the various tools and techniques used to answer these questions. Define What problem would you like to fix? In summary, Six Sigma DMAIC methodology is really just a series of common sense questions that one asks in order to solve any problem and eventually sustain the gains that come from solving the problem.

Define Define the problem. And if they do lose weight after taking such action, then the theory is validated.

For a creative change in which an organization changes course completely, however, the model is less applicable. This cyclical problem solving model seeks to improve the processes within an organization. In the Six Sigma approach, the statistical problem will then be converted into a statistical solution.

These efforts waste time, consume resources, create more variation and, often, cause new problems.

DMAIC Process

The purpose of this step is to identify the root cause relationships. This step does not only focus on control but proble, monitoring as well.


If the true causes of any problem sima discovered, then by controlling or removing the causes, the problem can be reduced sibma removed. In this phase the project team creates a Project Chartera high-level map of the process and begins to understand the needs of the customers of the process.

The first solution is chosen unanimously. This kind of mathematical language should not put anyone off. Has an obvious problem within an existing process Has the potential to reduce lead time or defects while resulting in cost savings or improved productivity Is measurable has collectable data and results in a quantifiable improvement There are obstacles to smooth operations in any business and Lean Six Sigma provides guidelines to help you select the right projects at the right time.

After a test period an solvjng takes place with all branches and management. Verification includes both process analysis and data analysis and has to be completed before implementing solutions.

The Six Sigma Approach: A Data-Driven Approach To Problem-Solving

The strengths of this problem solving approach lie in the addressing and optimizing of the root causes in a process. This is not a bad method, provided what one thinks is causing the problem is really causing the problem. The purpose of this step is to establish the most important aspects of the current process and to collect relevant data.

The Six Sigma approach follows a standard approach — DMAIC — that helps the problem-solver to convert the practical problem into a practical solution based on facts and data.

That means initially there are two focuses: A holistic approach that leaders embrace is more effective.


Improve Implement and verify the solution. A statistical problem is the problem that is addressed with facts and data analysis methods. Thus, discovering root causes is at the core of the methodology. Measurement is critical throughout the life of the project. The best results are achieved with a plan-led team approach. Every Six Sigma project goes through these five stages.

Six Sigma approach does not have room for gut feel or jumping to conclusions.

This solution is not based on gut feeling. Define, Measure, Analyse, Improve and Control. Subsequently, the data that was collected in the previous step is analysed. August 25, at 3: Actually it is really not so different from how people normally go about solving day-to-day problems, except in Six Sigma, nobody knows what is really causing the problem at the beginning of the project. Every output y is a function of one or multiple inputs x Any process which has inputs Xand delivers outputs Y comes under the purview of the Six Sigma approach.

All possible inputs in the process that may be causing the problem are compared and the critical few are identified.

If X is your cause, Y will not be regarded as the output. This field is for validation purposes and should be left unchanged. A structured improvement effort can lead to innovative and elegant solutions that improve the baseline measure and, ultimately, the customer experience.
