Which of the following is NOT one of the driving forces of Six Sigma?

Improving customer satisfaction is, in fact, a central tenet of Six Sigma, as it focuses on delivering high-quality products and services that meet or exceed customer expectations. When a company adopts Six Sigma practices, one of its primary goals is to enhance customer satisfaction by reducing process variation and minimizing defects. This aligns with the overall objective of maintaining competitive advantage by ensuring that customers are happy with the products and services they receive.

The other options presented are recognized components of the Six Sigma methodology. Getting everyone involved emphasizes the importance of team collaboration and engagement across all levels of an organization in the Six Sigma initiative. Continual improvement is a fundamental principle of Six Sigma, focusing on ongoing efforts to enhance processes and eliminate inefficiencies. Meanwhile, while the role of information technology can support Six Sigma projects, it is not strictly categorized as a driving force when compared to the more foundational aspects of customer involvement and process improvement.

Therefore, by understanding that improving customer satisfaction is integral to Six Sigma, one can appreciate why it is not the correct choice for this question.
