A Brief History of Six Sigma

Although the term sigma has been in parlance in statistical process control since the 1920s, Motorola first defined Six Sigma as a quality target in 1984. Quality improvement theory from the past 60 years, such as Total Quality Management and Zero Defects, aided in developing the formal methodologies used today.

Motorola eventually discovered that many of the tools and procedures essential to reduce faults in components manufacturing could work for other company sectors. Other significant corporations, such as Allied Signal, embraced the technique in the years that followed. However, Six Sigma rose to prominence in the late 1990s, when GE's chairman and CEO, Jack Welch, declared massive savings due to Six Sigma.

Although the ISO (International Entity for Standardization) issued the first Six Sigma certification in 2011, no one regulatory organization publishes the comprehensive body of knowledge. Companies, schools of higher learning, and consulting firms may provide slightly different requirements and training.

Lean manufacturing, which focuses on eliminating waste and increasing process flow, was merged with Six Sigma concepts in the 2000s, resulting in Lean Six Sigma. This framework provides firms with strategies for simplifying processes, discovering and eliminating faults and inefficiencies, and so on.

What Is the Lean Six Sigma Methodology?

The Lean Six Sigma structure works to improve the efficiency of a business process by implementing lean tools. Lean methodology finds defects that lead to wasteful process iterations—Lean Six Sigma methodology guides to produce high-quality products to keep the customer happy.

This course incorporates DMAIC and lean methodologies to help you become more skilled and implement them.

What is Six Sigma?

Six Sigma is an array of techniques and mechanisms whose particular implementation improves and manages the quality of business processes. Six Sigma strives to enhance the quality of the business processes by finding the defects and eliminating them from the root and upgrades the business process with an increase in iterations for accurate process results. The elevation in efficiency and reduction of defects ensures better quality and punctuality in product delivery. It helps keep the zeal in the team and build confidence right up to the subordinate level in the company.

Six Sigma pulls off almost perfect output by using the data-driven approach for quality control and problem detection in the business process. Six Sigma techniques use-value targets to set improvement goals that organizations achieve by executing up-gradation projects depending on predetermined steps by synchronizing sequences. 

The organization places Six Sigma technique teams to support, maintain, and complete tasks. Because it studies, measures, and makes business processes better in an organization. American organizations began using the Six Sigma methodology, which today is the worldwide drill to better business processes. The method's popularity is because it reduces waste, helps an organization comprehend customer needs, decreases production time, and reduces costs by half.

How Does Six Sigma Work?

The proper implementation of Six Sigma makes it dynamic, and all industries profit from the benefits of Six Sigma certification. Six Sigma proposes 100 percent customer satisfaction by leaving no room for defects. The Six Sigma perspective works meticulously to guarantee enhanced efficiency and potency business processes to deliver quality products to customers.

Six Sigma is a phenomenally conditioned approach that works on statistical analysis to start business processes by recording the methodology of doing work and uproots the probable cause of the problem to reduce defects and eliminate wastage thoroughly. The result is excellence in product and service creation. 

Six Sigma Techniques are beneficial not only to the organization and its customer but also to the employees. By raising performance standards, the employees can perfectly perform tasks, eliminating re-work.  

Six Sigma Principles

You will discover subtle variations on Six Sigma concepts depending on where you look. These are the concepts that govern the approach in general:

  • Creating consistent and predictable process outputs is critical to company success.
  • Characteristics of manufacturing and commercial processes can be defined, monitored, evaluated, improved, and controlled (see DMAIC below).
  • To achieve long-term quality improvement, the entire company must involve themselves, especially the higher and middle management.
  • All processes can be meticulously specified, studied, and improved: you can control the outputs if you can control the results.
  • You cannot undermine the importance of continuous evaluation. Stop the process to analyze what went wrong. 
  • Getting rid of variance saves money and lowers failure rates.

Benefits of Six Sigma Certification

  • Six Sigma was a new approach that focused on quantifiable goals, particularly financial targets. You may attain your objectives by making data-driven judgments based on statistical procedures rather than assumptions. Control charts have been there for a century. Still, it was the ability to take a methodology, adequately describe an issue up front, figure out what a customer needs, and then start digging in with these business and statistical tools that enabled Six Sigma to become strong.
  • Many firms credit Six Sigma with generating significant cost reductions. Motorola, for example, claims to have saved $17 billion. Although the first results of GE's work with Six Sigma were less than promising, the corporation claims that Six Sigma procedures saved them $12 billion between 1995 and 2000. Over half of Fortune 500 organizations adopt Six Sigma, which has resulted in over $400 billion in cost reductions over the last two decades.
  • Six Sigma is typically associated with large enterprises, and others argue that it requires significant adaption for small businesses. Furthermore, formal Certification may be prohibitively expensive for small businesses, particularly for more advanced certificates. On the other hand, experts consider Six Sigma as having benefits for all types of companies. They believe that smaller companies require Lean and Six Sigma more than larger businesses since they must compete on a much higher level to stay in business.
  • Although Six Sigma originated in the manufacturing industry, it has gained popularity in the commercial and service sectors. The complexity is in our inability to see the virtual, electronic processes, so the tools wind up being even more vital in that setting. You may visit the manufacturing floor to see the assembly line and timing the operations. Email and other electronic communications are necessary for many of our procedures in the corporate sector. However, having accurate data from such systems makes it simpler to time in different circumstances.
  • If you learned Six Sigma in manufacturing, adapting it to non-manufacturing settings, such as finance, needs certain mental modifications. It is handing over information from one department to another or within the same department, rather than putting a part down a conveyer belt. It's about tracing that value stream and figuring out where the bottlenecks are, what the delays are, and whether or not we should be waiting. Is there an overabundance of something? Are we overthinking things? We may still connect such quality-improvement principles to data or information.


If you want to improve your job chances and compensation, whether you're a graduate in any field, an engineer, or an MBA, get certified in Six Sigma certification. Start with a Green Belt and work your way up to the Master Black Belt to earn a higher salary. As a newcomer, you may begin studying Six Sigma principles by participating in a lean Six Sigma Green Belt certificate program. As you gain work and project experience, you can progress to higher certificate levels.
