Quality Function Deployment
Developed by Mitsubishi Kobe Shipyard 1972. Adopted By Ford and GM in 1980s, and later Xerox, Hewlett-Packard, AT&T.
Is a structured method to transmit and translate customer requirements, that is, through each stage of the product development process.
A systematic way of documenting and breaking down customer needs into manageable and actionable detail.
Quality Function Deployment is a Valuable , but it is not a
Foundation - Belief That Products Should Be Designed To Reflect Customer Desires and Tastes

Procedure of building HOQ
Identify customer requirements Identify product specifications Relate the customer requirements to the product specs. Conduct an evaluation of competing products. Evaluate product specs and develop targets. Determine which product specs to deploy in the later
development stages.

Spirits of QFD
The voice of the customer MUST be carried THROUGHOUT the production process.
Three other HOQs are used to do this and, together with the first, these carry the customers voice from its initial expression, through design attributes, on to component attributes, to process operations, and eventually to a quality control and improvement plans.
In Japan, all four are used. the tendency in the West is to use only the first one or two.
