Thesis Title
Improvement to Quality Function Deployment Methodology

Read article at Massey Research Online: MRO icon

Quality Function Deployment (QFD) is a product design and improvement methodology that translates customer wants and needs into technical design attributes, using multidimensional categorical data in the form of matrices, collectively known as the 'House of Quality' (HOQ). Designers and engineers using QFD often fail to fully integrate the various HOQ matrices, or consider the full range of information potentially contained within them. Mr Iqbal developed innovative heuristics and methods to overcome these deficiencies. The methods developed include: applications of permutation and parametric bootstrap sampling to enable inferential statistical analysis; applying the Manhattan distance measure to roof matrix correlations, and using state multipole moments to examine higher order moments from Likert scale data. Published case examples were used to demonstrate the advantages of each technique. Mr Iqbal's research supports practitioners to achieve better outcomes when using QFD or other methods where Likert scale data are employed
