Comprehensive QFD

Gustafsson (1995) notes that

According to Akao (1990) the definition of QFD reflects two purposes:

• Quality deployment: focus on the product, deployment of customer needs and requirements together with other important areas of of the product, e.g. technology, cost, reliability etc.
• Quality function deployment in the narrow sense: focus on the processes, deployment of quality activities in the functional organization.

Together these two purposes create 'Quality function deployment in the broad sense' or Comprehensive Quality Function Deployment.

Comprehensive QFD include the simultaneous deployment of:

Quality

Technology

Cost

Reliability

The quality deployment component of comprehensive QFD is shown below. Note that the roof and side roof on the charts correspond to a deployment, in the sense of the systematic diagram, rather than to the correlation matrix used in the USA for the house of quality.

The quality chart is the key to quality deployment. But we must remember that it is only one chart of many in the Bob King matrix of matrices (King, 1989), which provided the West with it's first glimpse of a recent version by Prof Ohfuji (Ofuji, 1995) shown below.
