House of Quality - VOC vs. Technical Requirements

This house of quality sample illustrates VOC vs. technical requirements. It was designed on the base of the figure 3-3 in Lecture "How QFD helps in product quality improvement?" from the website of National Programme on Technology Enhanced Learning (NPTEL), India.

Each engineering characteristic must directly affect a customer perception (VOC) and be expressed in measurable terms. Implementation of the customer requirements in design is difficult until they are translated into counterpart technical characteristics. Counterpart technical characteristics are an expression of the voice of the customer in technical language and specifications. For example, a customer requirement for an automobile might be a smooth ride. This is rather an abstract statement, which is important from the point of view of selling an automobile. Technical characteristics for a smooth ride can be appropriate dampening, anti-roll, and stability requirements. These are the primary technical descriptors or characteristics. Engineering knowledge and brainstorming among engineering staff’s is a suggested method for determining technical characteristics. Figure 3-3 shows the different technical requirements which can address all VOC for the bike stem design."
