Which statement about Six Sigma, ISO 9001, and Lean Systems best describes their status as quality management programs?

• A. Six Sigma is the only program that emphasizes teamwork and leadership.
• B. Lean Systems requires formal third-party certification in all firms.
• C. ISO 9001 discourages leadership and collaboration.
• D. All three are recognized quality management programs, customer-focused, and implemented firm-wide.

Answer: (D)

All three are recognized quality management programs that center on delivering value to customers and are meant to be adopted across the organization. Six Sigma uses data-driven methods and cross-functional teams led by champions to reduce defects. Lean focuses on eliminating waste and creating smooth workflow with strong frontline and management involvement. ISO 9001 provides the requirements for a quality management system, emphasizing leadership, customer focus, and continual improvement; certification by third parties is available but not required in every case. Because each framework aims at organization-wide quality and customer value, the statement that best describes their status is that all three are recognized quality management programs, customer-focused, and implemented firm-wide. The other options misstate aspects like exclusive teamwork emphasis, mandatory third-party certification for Lean, or ISO 9001 discouraging leadership.
