ABSTRACT
In the previous chapter, I examined a method by which customer needs may be identified and ranked. Then, I developed a matrix to relate the what of a customer need to the how that need is satisfied in a product. Developing the matrix of What-s against How-s is the basis of developing and using a tool that in the English language is called Quality Function Deployment (QFD). This technique has gained a wide degree of acceptance as a robust tool in the initial stages of requirements and concept development. See, for instance, Juran and De Feo (2010), Weiss (2013) or Ullman (2010).
