Implementing Six Sigma is fundamentally linked to reducing the number of defects in a process, with a benchmark of 3.4 Defects Per Million Opportunities (DPMO) serving as a critical justification factor. This specific metric reflects Six Sigma's goal of achieving near-perfect quality. The emphasis on reaching such a low level of defects showcases an organization's commitment to quality improvement and operational excellence.

By aiming for this standard, companies can not only enhance customer satisfaction but also drive down costs associated with defects, rework, and waste. This focus on quality improvement helps to create a culture of continuous improvement within the organization.

While aspects like high production speed, reduced labor costs, and employee training costs can be important considerations for a business, they do not encapsulate the fundamental intent of Six Sigma. The primary focus is on reducing defects, thus ensuring consistent and reliable outcomes, which is why the DPMO metric is a cornerstone justification for embarking on Six Sigma initiatives.
