What is Six Sigma?

Six Sigma is a set of principles that are used to improve processes and reduce waste. Six Sigma also uses data-driven decision-making, allowing companies to make decisions based on solid data instead of guesswork or assumptions. Six Sigma helps organizations identify opportunities for improvement, measure performance against customer requirements, and develop solutions to address issues quickly and effectively.

Six Sigma aims to minimize variance and defect rates using statistical analysis. Six Sigma employs statistical methods to achieve this. Six Sigma is all about inspecting the supply chain for flaws, recognizing problems, and resolving them as efficiently as possible.

What is Lean Six Sigma?

Lean Six Sigma is a Six Sigma Curriculum program incorporating “lean” ideas. The Lean method eliminates waste and maximizes customer value with minimal expenditure. Lean is less focused on manufacturing than Six Sigma and affects all aspects of a business.

Lean Six Sigma integrates these two waste-reduction approaches and helps companies discover and fix inefficient processes. This interplay between lean and Six Sigma techniques helps remove processes that don’t add value to the company.

Many Six Sigma Black Belt programs are Lean Six Sigma programs, even though the word “lean” is not included in the name. Regarding certificates, the distinction between the two techniques is who backs them. Six Sigma is governed by the ASQ (American Society for Quality), while Lean Six Sigma is governed by the International Association for Six Sigma Certification (IASSC).
