Prepared by:Shubhransu Patel

Introduction A method of transferring customer needs and requirements

into technical specifications for new product and service development.

Method to transform user demands into design quality.

Quality assurance and quality control points with function deployment used in value engineering.

QFD is designed to help planners focus on characteristics of a new or existing product or service from the viewpoints of market segments, company, or technology-development needs.

QFD helps transform customer needs (the voice of the customer [VOC]) into engineering characteristics (and appropriate test methods) for a product or service, prioritizing each product or service characteristic while simultaneously setting development targets for product or service.
