Why there was a need to have Six Sigma in Motorola?

Motorola uses Six Sigma to maintain high efficiency by eliminating waste and defect as they discover them. This may be on a production line or even in administration. Six Sigma aims to improve quality by minimizing variation and (overlapping with Lean) reducing waste.

How did Motorola define the concept of Six Sigma quality?

Six Sigma is a tool that Motorola developed years ago to promote quality throughout an organization, which, in turn, would eliminate defects in manufacturing. This concept, which is over 10 years old, is coming to the fore at a time when the quality movement is at a crossroads.

Why did Six Sigma start?

Who introduced notion of zero defects?

Philip Crosby
One of the most influential ideas about this was the notion of “zero defects.” This phrase was coined by Philip Crosby in his 1979 book titled, “Quality is Free.” His position was that where there are zero defects, there are no costs associated with issues of poor quality; and hence, quality becomes free.

What is the concept of 6 Sigma?

Six Sigma is a statistical- and data-driven process that works by reviewing limit mistakes or defects. It emphasizes cycle-time improvements while reducing manufacturing defects to no more than 3.4 occurrences per million units or events.

Why it is called Six Sigma?

The name Six Sigma is derived from the bell curve used in statistics where one Sigma represents one standard deviation away from the mean. The defect rate is said to be extremely low when the process exhibits Six Sigma’s, where three are above the mean and three below.

What is the importance of acquiring zero defects in TQM?
