What does Six Sigma aim to eliminate in production processes?

Six Sigma is a data-driven methodology that focuses on improving the quality of processes by identifying and eliminating defects. The primary goal is to achieve a level of quality where the number of defects is reduced to a minimum, aiming for no more than 3.4 defects per million opportunities. This methodology utilizes a systematic approach to problem-solving and relies on statistical tools to analyze processes, ensuring that each step contributes positively to the final output.

While Six Sigma may indirectly address other issues such as wastes, delays, and overproduction through its emphasis on process improvement, the core focus is specifically on defects. By eliminating defects, organizations can enhance product quality, improve customer satisfaction, and increase efficiency, which ultimately contributes to a sustainable competitive advantage.
