Using QFD in Product Development
The Triptych QFD Worksheet can be used to translate customer needs (WHATS) into to marketing, engineering, or manufacturing requirements (HOWS) based on the strength of the inter-relationships between the Whats and Hows. The traditional House of Quality is constructed in Triptych and the results can automatically flow down from one house to another.
Benefits of QFD:
- Dispels the "business as usual" approach to planning and design
- Revises operational norms
- Directors and managers become "team members"
- Functional managers are required to donate the services of personnel
- Decision authority is with teams and not individuals
- Lines of communication are established between functions at the working level
