Introduction to Six Sigma

Are you looking to improve the quality of your business processes? Do you want to reduce waste and increase efficiency? If so, then Six Sigma might be the solution you're looking for!

Six Sigma is a data-driven methodology that aims to improve the quality of processes by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. It was first introduced by Motorola in the 1980s and has since been adopted by many organizations worldwide.

In this article, we'll provide an introduction to Six Sigma, including its history, methodology, and benefits.

History of Six Sigma

Six Sigma was first introduced by Motorola in the 1980s as a way to improve the quality of their products and processes. The term "Six Sigma" refers to the statistical measure of how far a process deviates from perfection. A process that operates at Six Sigma has a defect rate of 3.4 defects per million opportunities (DPMO), which is considered to be near-perfect quality.

The methodology was later popularized by General Electric (GE) under the leadership of Jack Welch in the 1990s. Welch made Six Sigma a central part of GE's business strategy, and the company credited it with saving billions of dollars in costs and improving customer satisfaction.

Since then, Six Sigma has been adopted by many other organizations, including healthcare, finance, and government agencies.

Methodology of Six Sigma

The Six Sigma methodology is based on a five-step process known as DMAIC, which stands for Define, Measure, Analyze, Improve, and Control. Let's take a closer look at each step:


The first step in the Six Sigma process is to define the problem or opportunity for improvement. This involves identifying the process that needs improvement, defining the scope of the project, and setting goals and objectives.


The second step is to measure the current performance of the process. This involves collecting data on the process and analyzing it to determine the current level of performance. This data is used to establish a baseline for future improvements.


The third step is to analyze the data to identify the root causes of the problems or opportunities for improvement. This involves using statistical tools and techniques to identify the factors that are contributing to the process variability.


The fourth step is to improve the process by implementing solutions that address the root causes of the problems. This involves developing and testing solutions, and then implementing the most effective ones.


The final step is to control the process to ensure that the improvements are sustained over time. This involves developing a plan to monitor the process and make adjustments as needed to maintain the improved performance.

Benefits of Six Sigma

There are many benefits to implementing Six Sigma in your organization. Here are just a few:

Improved Quality

Six Sigma is all about improving the quality of your processes. By identifying and removing the causes of defects, you can improve the quality of your products or services and increase customer satisfaction.

Increased Efficiency

Six Sigma can also help you increase efficiency by reducing waste and minimizing variability in your processes. This can lead to cost savings and improved productivity.

Better Decision Making

Six Sigma is a data-driven methodology, which means that decisions are based on facts and data rather than opinions or assumptions. This can lead to better decision making and more effective problem solving.

Improved Employee Engagement

Six Sigma involves employees at all levels of the organization in the improvement process. This can lead to increased employee engagement and a sense of ownership in the success of the organization.


Six Sigma is a powerful methodology for improving the quality of your processes and increasing efficiency. By following the DMAIC process and using statistical tools and techniques, you can identify and remove the causes of defects and minimize variability in your processes.

If you're interested in learning more about Six Sigma, there are many resources available online, including training courses, books, and certification programs. Whether you're a small business owner or a large corporation, Six Sigma can help you achieve your goals and improve your bottom line.
