Explain the concept of QFD. How do the elements of the QFD diagram link to our class discussions (e.g., the right side of the QFD diagram is all about defining quality). Then explain how the QFD diagram should be implemented in an organization and how the QFD diagram can be used cross functionally (across departments) to improve quality (you might want to review the approach of Crosby, from Week 2, as you answer this question).
