QFD is a planning tool that allows the flow down of high-level customer needs and wants through to design parameters and then to process variables critical to fulfilling the high-level needs. By following the QFD methodology, relationships are explored between quality characteristics expressed by customers and substitute quality requirements expressed in engineering terms. In the context of DFSS, we call these requirements "Critical-To" characteristics. These critical-to characteristics can be expanded along the dimensions of speed (critical to delivery, CTD), quality (CTQ), cost (CTC) as well as other dimensions. In the QFD methodology, customers define their wants and needs using their own expressions, which rarely carry any actionable technical terminology. The voice of the customer can be affinitized into a list of needs and wants which can be used as input to a relationship matrix, which is called QFD's House of Quality (HOQ).
Quality Function Deployment (QFD) links the needs of the customer (end user) with design, development, engineering, manufacturing, and service functions. As a quality system that implements elements of Systems Thinking with elements of psychology and knowledge, QFD provides a system of comprehensive development process for:
