What is Lean Six Sigma?

Lean Six Sigma is the fusion of the following two popular business principles into a single methodology- Six Sigma and Lean. This team-focused managerial approach aims at improving organizational performance and eliminating waste processes that involve time, physical resources, effort, and talent. Therefore, Lean Six Sigma propagates the idea that any use of resources that do not create value for the end customer is a waste and must be eliminated.

Lean Six Sigma acknowledges the role of stakeholders in every project's success. Consequently, it realizes the importance of compiling and analyzing data to foster a keen understanding of the effectiveness/ ineffectiveness of the workflow for stakeholders. 

Six Sigma History

Six Sigma was developed by Bill Smith in 1986. Later an engineer aimed to help improve the company’s devices which didn’t meet the quality standards at the time. He based the approach on statistical and quality control methods taught by Walter Shewhart, Ronald Fisher, and Edwards Deming, that were:   

  • Walter Shewhart pioneered statistical quality control (SQC) and also came up with the Plan Do Check Act (PDCA) model.
  • Edwards Deming is credited with developing the sampling techniques used by the Department of Census and the Bureau of Labor Statistics in the US.
  • Sir Ronald Aylmer Fisher’s work popularized many statistical techniques used today. For instance, Student’s t-distribution, P-value, F-distribution, among others.

Six Sigma vs Lean Six Sigma 

Six Sigma and Lean Six Sigma are closely related strategies that strive to solve process problems. They help companies make substantial improvements in efficiency, quality, and time use by examining their function processes. Employing the DMAIC phases, both methodologies help create a problem-solving workplace culture.

While Six Sigma is focused on minimizing defects and process variability for the improvement of the process output and quality, Lean Six Sigma concentrates on reducing/eliminating defects and the wasteful use of resources to enhance workflow and produce more value for customers.

Therefore, Lean Six Sigma is ideal for companies aspiring to simplify their processes and deliver ultimate value for the customer. The DMAIC method provides a clear roadmap, while phased thinking serves as a valuable tool. Contrastingly, the traditional Six Sigma methodology focuses just on defect prevention. 

What is the Six Sigma Certification?

Six Sigma is a certification program aimed at educating individuals in the process of analyzing processes and outcomes in the pursuit of reducing waste and reducing defects. The certification process involves several levels, ranging from a primary end user to a master Six Sigma user.

Six Sigma is a set of tools and techniques used by companies to improve production processes, eliminate defects, and guarantee quality.
