Prevention of water leakage in the shallow well jet pump through the application of total quality function deployment technique

Abstract

Engineers and managers have been adopting quality function deployment (QFD) technique to translate the voice of customers into technical parameters and values for improving the quality of products. During the recent years, certain difficulties of applying QFD in practice have been reported. In order to overcome these difficulties, the researchers have been evolving advanced models of QFD. In the research being reported here, one of such advanced models namely total quality function deployment (TQFD) was applied in a manufacturing company to prevent water leakage in a type of pump called shallow well jet pump. The solutions evolved were implemented by releasing the work instructions in this company. This experience indicated that TQFD is a suitable technique for translating the voice of customers into technical languages in a manufacturing company in which employees possess inadequate expertise to develop House of Quality of QFD technique.
