A structured method is called quality function deployment (QFD) that translates the voice of the customer into both of the product and service development. The architecture of QFD is composed of a set of matrices that is often referred to as the house of quality (HOQ). HOQ is regarded as a part of the QFD process. The matrices of HOQ include the importance of customer requirements and the relat...

Traditional QFD planning method compromises contradictions between engineering characteristics to achieve higher customer satisfaction. However, this compromise trade-off can not eliminate the contradictions existing among the engineering characteristics which limited the overall customer satisfaction. QFD (Quality function deployment) integrated with TRIZ (the Russian acronym of the Theory of ...
