what is six sigma approach?

Answer 1

Hello Nancy

People often view Six Sigma as a rigorous statistical quality control mechanism that reduces defects to 3.4 in a million opportunities. Rather, it can more broadly be thought of as a way of using statistics to understand customer needs better and to manage business processes to meet those needs.

Translating customer expectations and experiences into a language of numbers is the first step in measuring and improving our processes. In statistical terms, customers expect the mean, or our target for performance. Mean is also referred to as the arithmetic “average” in common language. What customers actually experience, however, is known as variation from the mean. For example, how often do we notice timely delivery from a thirty-minute pizza delivery shop? In contrast, we always take note of delayed deliveries, or that shop’s variation.

If we can measure process variations that cause defects, defined as unacceptable deviation from the mean or target, we can work towards systematically managing variation to eliminate those defects. Six Sigma provides a methodology to achieve this.

Hope it helps you understand...

With warm regards,

SKS
