What is Customer Requirements Prioritization in QFD?

Customer Requirements Prioritization in QFD assigns weights to voice-of-customer inputs using methods like AHP, ANP, and fuzzy logic to guide product design decisions in the House of Quality matrix.

This subtopic integrates analytic hierarchy process (AHP) and analytic network process (ANP) with QFD to rank customer requirements by importance (Kwong and Bai, 2003; Karsak et al., 2002). Fuzzy optimization models handle uncertainty in prioritization (Kahraman et al., 2004). Over 10 papers from 1988-2007 address these techniques, with Hauser (1988) foundational at 2275 citations.

Key Challenges

Why It Matters

Prioritization focuses resources on high-value customer needs, improving product success in automotive and electronics sectors (Hauser, 1988; Griffin and Hauser, 1993). Kahraman et al. (2004) applied fuzzy ANP in QFD for supplier selection, enhancing decision accuracy. Karsak et al. (2002) combined ANP with goal programming, reducing design costs by aligning engineering priorities with customer voices in case studies.

Key Research Challenges

Handling Requirement Interdependencies

Customer requirements often influence each other, complicating prioritization in QFD matrices. ANP addresses this over AHP by modeling networks (Karsak et al., 2002; Kahraman et al., 2004). Validation through case studies remains inconsistent across industries.

Managing Prioritization Uncertainty

Subjective customer data introduces vagueness, addressed by fuzzy AHP methods (Kwong and Bai, 2003). Extent analysis in fuzzy AHP computes weights but struggles with non-linear uncertainties. Empirical testing in product design shows sensitivity to fuzzy membership functions.

Integrating Multi-Criteria Methods

Combining AHP, ANP, and TOPSIS with QFD requires consistent scaling (Ho, 2007; Lin et al., 2007). Literature reviews highlight inconsistent applications leading to biased weights. Case studies in electronics validate hybrids but lack standardization.
