Importance of Taguchi's Method in Optimization of Various Problems in Service Sector

Taguchi’s parameter design approach offers a step by step methodology for optimization of various parameters with regard to performance, quality and cost [1]. The quality of design may be enhanced by enhancing the quality and productivity in different organization-wide performances. Those performances concerned with quality incorporate in quality of product planning, product design and process design [2]. During the decades after the introduction of Taguchi's method it was applied in diverse industries specially in manufacturing and production industries. Despite numerous applications of the technique in industrial processes, it was rarely used in service processes.
