House of Quality drawing Software

Are customer requirements considered in all your processes?
Do you translate customer requirements into organisational language?

QFD (Quality Function Deployment) was developed to improve customer satisfaction. It recognises that just understanding customer requirements is not sufficient to produce according these requirements.

It is QFD's insight that customer requirements must be allowed to determine all organisational processes and designs.

Therefore, QFD can be described as a tool to translate customer requirements into inputs for organisational processes and designs.

QFD consequently includes everybody in servicing the customer.

House of Quality: Document your QFD efforts

The House of Quality is a comprehensive matrix used in QFD (Quality Function Deployment) to translate customer requirements into prioritised engineering targets to be met by a new product design.

The House of Quality can be used as a stand alone tool to respond to a specific problem. Or it can be used within a more complex system like the 'Four-Phase Model'. It is a plan of four stages in which a QFD team translates:

customer requirements to product characteristics
product characteristics to part characteristics
part characteristics to process targets
process targets to production targets

The general format of the House of Quality consists of six components:

Customer requirements (HOWs) listing the requirements derived from customer statements.
Technical requirements (WHATs) comprising relevant and measurable product characteristics.
Planning matrix illustrating customer perceptions observed in market surveys.
Interrelationship matrix illustrating the QFD team's perceptions of interrelationships between technical and customer requirements.
Technical correlation (Roof) matrix identifying where technical requirements support or impede each other in the product design.
Technical priorities, benchmarks and targets recording priorities assigned to technical requirements by the matrix, measures of technical performance achieved by competitive products and the degree of difficulty involved in developing each requirement.
