What is Lean Six Sigma?

The Six Sigma training framework for beginners is a variation that combines the 5 steps of Lean Management principles and Six Sigma resources and belts hierarchy. Six Sigma is focused on reducing variability among deliverables and waste. Lean Management focuses on reducing production cycle time and waste. Six Sigma is focused on fixing and finding defects after the fact while Lean focuses on preventing defects from ever occurring. Lean is best implemented by first increasing efficiency. Six Sigma methods then are used for fine-tuning. Lean Six Sigma is used in manufacturing, finance, IT, and other areas.

Sermin Vanderbilt, Founder of the Six Sigma World Conference, and President of the American Quality Institute. She says that Six Sigma is getting it right all the time, or most of them, 99.9% of the time. Six Sigma is a requirement for almost every company. Six Sigma is all about accuracy. Lean is all about cutting costs and cutting time.

What is Six Sigma, in short? Jack Welch, one of its most prominent proponents, said that Six Sigma was a quality program that improves customer experience, lowers costs, and creates better leaders.

Six Sigma vs. Lean Six Sigma

Six Sigma and Lean Six Sigma for beginners both aim to solve problems in processes. By examining the function processes, they help companies improve efficiency, quality, and time usage. Both methodologies create a culture of problem-solving by using the DMAIC stages.

Lean Six Sigma focuses on eliminating defects, reducing waste, and maximizing workflow to produce more value for clients.

Lean Six Sigma, then, is the ideal solution for companies that want to simplify processes and provide ultimate value for their customers. The DMAIC methodology provides a clear road map, and phased thinking is a valuable tool. The traditional Six Sigma 5 step method, on the other hand, focuses solely on defect prevention.

The History of Six Sigma

Motorola introduced Six Sigma in 1984 as a quality goal. Although the term “sigma” was used in statistical process control as far back as the 1920s, Motorola’s first use of the term “sigma” was in the 1920s. These formal methods were developed from 60 years of quality improvement theory including Total Quality Management, and Zero Defects.

Motorola discovered that many of the same lean and six sigma tools and methods they used to reduce defects in parts manufacturing could be applied to other areas of their business. Other large companies, such as Allied Signal, adopted the method over the years. Six Sigma was a true star in the 1990s, when Jack Welch, GE’s CEO, announced remarkable savings due to Six Sigma.

ISO (International Organization for Standardization), published the first Six Sigma certification in 2011. However, no single Six Sigma organization publishes the complete body of knowledge. There may be standards and training offered by companies, colleges, universities, or consulting firms that are slightly different.

In the 2000s, Lean Manufacturing was created with an emphasis on streamlining processes and reducing waste. Six Sigma principles were also used to create Lean Six Sigma. This framework provides organizations with methods for streamlining processes and then detecting or eliminating defects and inefficiencies.

What are the Six Sigma Principles of Excellence?

As beginners, you’ll see slight variations in Six Sigma belts hierarchy principles depending on where you look for the resources. These are the principles that guide the approach.

  • Business success is dependent on constant efforts to ensure predictable and stable process results.
  • Manufacturing and business processes can be measured, analyzed, improved, and controlled.
  • To achieve sustained quality improvement, the whole organization must be committed, especially the upper and middle management.
  • Every process can be described and analyzed in detail. You can also improve them.
  • It is important to continue to evaluate your performance. You must stop doing what you are doing and evaluate what went well or poorly.
  • Eliminating variation reduces cost and improves the quality

Six Sigma Methodology Resources

Six Sigma principles for beginners are implemented through methods, or roadmaps for improvement, such as a workflow. DMAIC is the main methodology and DMADV is the second.


DMAIC focuses on improving existing processes incrementally with these 5 steps of the Six Sigma belts hierarchy. This is Six Sigma’s most well-known methodology resource. Here is a breakdown of the acronym.

D Define customer requirements and project goals.

M: Determine the main aspects of your current process. McAdams states, “This is where you begin to understand your process. This is when data can be collected on it.”

A: Analyze data. You need to find out what errors are common and where they occur in order to target them. It always looks at the 80/20 rule. McAdams says, “Let’s see if 20 percent of those reasons give us 80 percent of our defects. Then let us reduce them.”

I: Enhance processes. Verify that the improvements are working.

C Monitor future implementations to prevent errors from reoccurring.

DMADV focuses on improving new products and processes in accordance with the 5 steps of Six Sigma standards and resources. Here is a breakdown of the acronym.

D: Define company or customer goals.

M Measure Critical Quality (characteristics that are critical to quality) assess product capabilities, production process ability, and risk.

A: Analyze your measurements.

D: Design the new process that is based on the results of the previous step.

V: Check the design with a pilot run and then implement the new process. Then, hand it over to the process owner.


The primary use of Design for Six Sigma (DFSS) involves the complete redesign of a process or product. The DFSS process seems to be implemented differently by each business or organization.

Six Sigma Analysis Tools

Six Sigma belts hierarchy for beginners employ various tools during the phases of these methodologies to analyze and measure processes and their outcomes. Here is a partial list of some of the most commonly used six sigma tools and resources:

Six Sigma Certification Levels

There are different hierarchy of belt levels of six sigma certification, such as White Belt, Yellow Belt, Green BeltBlack Belt, and Master Black Belt.
