Determine Technical Correlations among Product Features
Such is section 3 in figure of Generic Form of Matrix in QFD. The different product features will likely be concerned to each other in different ways. The cause of this chart is to found the strength of each of the relationships amongst pairs of product features. Instead of employing symbols, as previously implied, now we adopt the numerical ratings represented in Table no.2 for our illustrations. Such numerical scores imply significance of strong relationship amongst respective pairs of requirements.
