“…Developed by Akao in Japan, QFD is a method to convert user's needs into technical requirements during each step of producing products and delivering services (Chan & Wu, 2002). Quality function deployment (QFD) has the following advantages: firstly it pays more attention to "customers' voice", has a better understanding of customers' needs and helps to fulfill user's expectations; secondly by a systematic prioritization, it contributes to identify process improvements, which means QFD is an effective way to identify aspects that are vital for users; furthermore, QFD is also a critical method for quality control (Hunt & Killen, 2004;Gremyr & Raharjo, 2013;Moores, 2006;Buttigieg et al, 2016;Lim & Tang, 2000).
