Which of the following functions is primarily concerned with maintaining quality standards in Six Sigma?

The quality council is primarily concerned with maintaining quality standards within the Six Sigma framework. This group typically includes representatives from various departments and is responsible for setting and enforcing quality policies and standards across the organization. The quality council plays a critical role in overseeing Six Sigma initiatives, ensuring that projects align with the organization's overall quality objectives, and providing guidance and support to project teams.

By establishing and maintaining quality standards, the quality council helps foster a culture of continuous improvement and accountability. They provide the strategic oversight necessary to ensure that quality is not just an operational concern but is integrated into the organization’s overall strategy. This includes approving projects, monitoring progress, and ensuring that the methodologies and tools used in Six Sigma efforts are effectively applied to meet the established quality benchmarks.

In contrast, other functions like the process owner focus on overseeing individual processes, the executive steering council typically deals with broader strategic direction and resource allocation, while the project team is engaged in executing specific Six Sigma projects rather than maintaining overarching quality standards.
