Quality Function Deployment (QFD) is a structured approach used in production and operations management to translate customer needs and requirements into engineering characteristics and product specifications. The process aims to ensure that the voice of the customer (VOC) is effectively incorporated into the design and manufacturing processes, leading to products that meet or exceed customer expectations. QFD was first developed in Japan in the late 1960s and is now widely used across industries to improve product development.

At the core of QFD is the concept of transforming customer desires into technical specifications that guide the product design process. It involves a set of matrices known as the "House of Quality," which is used to prioritize customer requirements and identify the necessary design parameters to meet those requirements. The process starts with gathering and analyzing customer needs, followed by creating product specifications that fulfill these needs.

To translate the customer’s voice into product specifications, the QFD process involves several key steps:
