Which of the following is NOT a benefit of using Six Sigma?

In the context of Six Sigma, benefits are focused on improving processes and the overall performance of an organization. The implementation of Six Sigma methodologies is aimed at enhancing quality and efficiency within processes. Options such as increased operational efficiency, reduction in defects, and improved customer satisfaction are all significant advantages that arise from the adoption of Six Sigma practices.

In contrast, a reduction in employee engagement does not align with the goals of Six Sigma. In fact, one of the aims of Six Sigma is to involve employees in process improvement initiatives, which typically leads to higher levels of engagement. An engaged workforce often results in better execution of processes, contributing to the overall effectiveness of Six Sigma initiatives. Therefore, the notion that Six Sigma leads to reduced employee engagement stands out as incorrect, making it the option that does not represent a benefit of using Six Sigma.
