House of Quality

WHAT IS HOQ?

House of Quality is a graphic tool for defining the relationship between customer desires and the firm/product capabilities. It is a part of the Quality Function Deployment (QFD) and it utilizes a planning matrix to relate what the customer wants to how a firm (that produces the products) is going to meet those wants.

It looks like a House with correlation matrix as its roof, customer wants versus product features as the main part, competitor evaluation as the porch etc. It is based on "the belief that products should be designed to reflect customers' desires and tastes" (Hauser & Clausing 1988). It also is reported to increase cross functional integration within organizations using it, especially between marketing, engineering and manufacturing.

The basic structure is a table with "Whats" as the labels on the left and "Hows" across the top. The roof is a diagonal matrix of "Hows vs. Hows"
