Which structure within Six Sigma is focused on quality assurance and development?

The quality council is primarily focused on overseeing quality assurance and development within an organization. Its role involves setting quality standards, establishing quality policies, and ensuring that these standards and policies are being adhered to across various departments or processes. The council typically includes high-level management and key stakeholders who are responsible for strategic decision-making related to quality initiatives.

In the context of Six Sigma, the quality council is vital as it gives direction and support to Six Sigma projects, ensuring alignment with the organization's overall quality goals. It also monitors the impact of these initiatives on business performance and addresses any barriers to quality improvement.

While the other options may play important roles in the broader Six Sigma framework, they do not specifically focus on quality assurance and development in the same structured and overarching manner that the quality council does. For instance, the process improvement group is more centered on executing specific projects, the executive steering committee typically oversees strategic direction and alignment but not day-to-day quality assurance, and the training division is responsible for educating employees rather than directly managing quality standards and policies.
