Questions & Answers

Q: How did Six Sigma gain popularity?

Six Sigma gained popularity when Jack Mills made it the central focus of his business strategy at General Electric in 1995. Today, it is widely used in different sectors of industry.

Q: What is the significance of the Sigma capability?

Sigma capability, indicated by the Sigma value, measures how well a process is performing. As the Sigma capability increases, the cost of poor quality decreases, while profitability, productivity, and customer satisfaction increase.

Q: What is the goal of Six Sigma?

The goal of Six Sigma is to minimize defects within the Six Sigma range, striving towards zero defects. It aims to improve the quality of output by identifying and removing the causes of defects and minimizing variability in processes.

Q: How is Six Sigma performance measured?

Six Sigma performance is measured using the defect rate per million opportunities. A higher Sigma level indicates better quality, with the ideal being Six Sigma (3.5 defects per million opportunities).
