The DMAIC Model and Its Effects on Business Success

Six Sigma aims at reducing variations in a business and manufacturing process via dedicated improvements in the various processes. This requires a sustained commitment from all members of the organization.

This principle has been perfectly brought about by the DMAIC methodology, which aims at bringing about process improvement by eliminating defects. It is generally defined as a set of practices which are aimed at bringing about improvement in efficiency and eliminating defects.

Among the many methodologies and strategies that Six Sigma allows is the DMAIC Model. It stands for Define-Measure-Analyze-Improve and Control. This model plays an important role in making the Six Sigma initiative a success for businesses. Black Belts follow this model to base their process improvement projects BRI.

The model was developed by Edwards Deming, aimed at reducing defects through improvement in processes.

Let’s have a look at the various phases.


This is the first step that refers to defining the goals of the project. Process improvement goals may be aimed at increasing market share, the output of a particular department, bringing about improved employee satisfaction as well as customer satisfaction and so on.

The goal has to align the customer demands and the strategic goals of the organization. Data mining methods can be used to find prospective ideas for project implementation.

In other words, businesses are designing a road map for achieving the targets and goals of the organization.


This phase refers to the analysis of the existing system with various measurement techniques for the defects and levels of perfection that exist. In this step, accurate metrics have to be used to define a baseline for further improvements.

This helps Six Sigma team leaders understand if progress has been achieved when process improvements are implemented.


This phase is extremely important in order to determine any disparity that may exist in the goals set and the current performance levels achieved. Various statistical tools are available to undertake such an analysis.

The understanding of the relationship between cause and effect is necessary to bring about any improvements, if needed.


Improvements in existing systems are necessary to bring the organization towards achievement of the organization goals. Creative development of processes and tools brings about a new lease on life for the organization’s processes and takes them nearer to organizational objectives.

Various project management and planning tools can be used to implement these new techniques and processes. Appropriate usage of statistical tools is important to measure the data, which is necessary to understand improvements done and any shortcomings that may exist.


The last phase of DMAIC is the Control phase. It helps ensure that variations in the processes are rectified before they have a negative effect. Controls can be used to ensure sustained improvements in new processes and operating procedures.

The new project components should become a part and parcel of existing processes. Once all the factors are performing to satisfaction, transfer of ownership should be done to process owners and process teams.

The DMAIC model is extremely beneficial in bringing about the change which the Six Sigma project aims at and has the ability to show good business results.
