Abstract

Quality Function Deployment (QFD) was conceived in Japan in the late 1960's and used extensively by Toyota. QFD is a customer oriented approach to product innovation. It is the structured approach which define customer needs and translating them into specific plans to produce and to meet those needs. It is a quality tool that helps to translate the Voice of the Customer(VoC) into new products that truly satisfy their needs. The VoC is the term used to describe the stated and unstated customer needs. The quality improvement are based on the feedback of customers about new and existing product in the market and from benchmarking of competitors. In this paper, QFD technique is applied to the product (Impeller) to design, develop and implementation of the product quality. In the design of a new Impeller, QFD gave the most important parameters from customer point of view and then find out engineering characteristics. These important parameters are then put into House of Quality matrix [HoQ] to get the relation matrix between voice of customer and engineering characteristics. From the result of QFD applied to Impeller which short out the parameters those are," Regulate uniform flow of oil through impeller vanes, Holes, Thickness of vanes, Draft angle & no. of vanes, Constant RPM to motor, Cost, Total life span (hrs.), Less energy consumption". This are require modification according to voice of customer and used for new design.
