Multivariate statistical methods for quality creation: a review

This paper discusses the role of multivariate statistical methods in quality creation, i. e. for exploring customer needs, product quality deployment and management planning. A brief survey of methods are given from different ordering perspectives. Some thoughts are given to (i) common methods in marketing and consumer research (ii) matrix data analysis as one of ‘the seven management and planning tools’. At the end an example from Kano et al. concerning trends of quality elements is reanalysed by correspondence analysis and a perceptual map with some novel features is given.
