Intended learning outcomes: Explain quality function deployment – the house of Quality and 10 steps of implementation.
Continuation from previous subsection (18.2.3).
A typical method used in the quality planning phase is quality function deployment.
Quality function deployment (QFD) is step-by-step development of quality functions. The QFD process uses matrices to translate customer requirements into technical design parameters or characteristics.
To do this, a quality chart called the “House of Quality” is employed as a correlation matrix linking quality characteristics and target values and their tendency. See Figure 18.2.3.2.
Fig. 18.2.3.2 Quality function deployment: House of Quality and 10 steps of implementation (Source: [Guin93]).
The 10 steps of implementation in Figure 18.2.3.2 are taken from [Guin93]:
- Gather customer requirements for the product or service.
- Customers weight the importance of each of the requirements.
- Ask customers to rate competitors’ products or services.
- Technical descriptors. Translate customer requirements into quality characteristics.
- Determine relationship matrix between customers’ needs and technical descriptors.
- Estimation of the importance of the technical descriptors.
- Conduct analysis of competitor’s technical descriptors.
- Estimate degree of difficulty, technical feasibility.
- Determine target values for each technical descriptor.
- Determine variation for each technical descriptor and examine mutual reaction.
