You may have heard the term 6 Sigma as a project manager or manufacturer. You may have wondered what 6 Sigma means. You might have read a bit about it, but you think 6 Sigma is too complicated for you or would not add value in your business. You’re wrong! Six Sigma is based upon statistics, which can make it seem difficult. But if you take a free Six Sigma course, you’ll find that the Six Sigma Principles are actually very simple. To become a Six Sigma Green Belt, you will want to quickly enroll in a green belt training program.
Let’s start with a simple question: What exactly is 6 Sigma?
Six Sigma is a highly structured Business Improvement Process that companies use to focus on creating and delivering high-quality products and services. Six Sigma Certification allows you to become a Six Sigma practitioner.

Mikel Harry, President and CEO of Six Sigma Academy, defines 6 Sigma as:
“A business process that allows companies dramatically improve their bottom line by designing, monitoring, and controlling everyday business activities in a way that minimizes waste and maximizes customer satisfaction.”
Six Sigma is a customer-focused business improvement process. Every 6 Sigma project’s success is dependent on the efforts of everyone involved, from top to bottom. It is vital that all Team Leaders are educated about the evolution and workings of teams. This approach to problem solving is entirely data-driven and based on statistical tools. It is based on logic reasoning, which is why it is called logical reasoning.
The 6 Sigma Process Steps & Approach
The 6 Sigma process is made up of five steps, which can be abbreviated to DMAIC. It stands for Define. Measure, Analyze. Improve. And Control. It is the basis of 6 Sigma. DMAIC is the most well-known process for solving problems. DMAIC addresses issues such as defects, failures, deviations from a target or excessive cost or time. DMAIC addresses the improvement of Productivity (How Many), Financial(How Much Money), Quality/How Well and Time (How Fast – abbreviated PFQT.
You will often see the equation “Y=F(x”)” in 6 Sigma. This equation is the approach and mechanism of 6 Sigma. It is the core formula. “Y” is often referred to by the Output, while “X” is the Input. The process that produces the output is called F. This means that “Y is the function or combination of multiple Xs.” Remember that measuring Xs or Ys is not an end in and of itself. Xs must be related or connected to Ys.
Here are some examples. Take this example:
If “X” is the time of the cycle, then “Y” might be on-time delivery
If “X” refers to the quality of the work done, then “Y” might refer to the level of customer satisfaction.

6 Sigma is a process that aims to make the process more robust and reduce variability. This problem-solving approach has one important aspect: It “Applies to all processes”. You’re correct. No matter what industry, company, or domain you are involved in, 6 Sigma can be applied to any process. It can be applied to transactional processes as well as production processes.
Let’s take a look at some definitions of Six Sigma
Sigma
This process is called 6 Sigma. This process is five steps long, so why not give it five steps? This is because the standard deviation allowed to achieve 99% accuracy in a problem-solving process is the reason the process’s name. Literally, the Standard Deviation symbol is the 18th letter in the Greek alphabet, Sigma(s). The Standard Deviation measures how many numbers are spread out. It is also known as variation or dispersion. Six Sigma is a process that reduces variation in any process to six
