What is Six Sigma & its Benefits

Six Sigma (also written as 6-Sigma) is an approach for process and good quality management that uses a blend of various methods to help organizations improve their products and reduce their rate of error to lower costs and generate higher profits.

The term Six Sigma originated in the 18th century when Bill Smith from Motorola, also known as the father of Six Sigma, developed and introduced the Six Sigma principles to measure defects and improve quality. A Six Sigma process is the one in which 99.99966 % of the opportunities to produce products or features are statistically expected to be free of defects (3.4 defects per million). Motorola set a goal of “six sigma” for all of its manufacturing operations, and that goal became a mantra for the management to achieve.

The fundamental objective of the Six Sigma methodology is the implementation of a calculative strategy that focuses on process improvement and variation reduction. This is achieved via the use of two sub methodologies of Six Sigma that are,  DMAIC and DMADV. 

DMAIC: The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for the current existing processes falling below specification and looking for improvement in Increments

DMADV: The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to create and develop new processes or products at Six Sigma quality levels.

Both the processes mentioned above are executed by Six Sigma Green Belts. There are different levels of certification in Six Sigma starting with White belt, then Yellow belt, Green belt, Black belt, and finally level of a Master Black belt. These different belts in six sigma denote different levels of expertise. White belt is meant for students who want to get introduced to definitions and understand examples of Six Sigma concepts. Yellow belt is probably the first step of Six Sigma certification for practitioners of quality processes and the Master Black belt for leadership and successful process improvement plans.

The great thing about Lean Six Sigma is that it is universally accepted and used regardless of the size of the company, niche,  and geographical area. Right from automobiles to manufacturing companies, Six Sigma focuses on improving the processes.
