Development of Durian Chips Product by Apply of Quality Function Deployment

Abstract

The objective of this research was to develop a product of durian chips  through application of Quality Function Deployment (QFD) technique. The research methodology was a quantitative method. A customer requirements survey was conducted in Chanthaburi Province. The 384 customers were selected by simple random sampling for questionnaire during May – August 2016. Furthermore, the application of QFD method to develop durian chips has been reported the customer requirements to translate the technical requirements. In this research, a QFD technique conducted to translate Voice of Customers (VOCs) into the technical requirements for product planning. The top five customer requirements to develop durian chips were identified as natural color shade, crispness, thin sheet, non rancid and natural taste. The research results revealed that the calculation of relative important to translate the technical requirements (TRs) identified that the “drying, vacuum packaging, seasoning, storage time and grading” were the highest requirements to the overall improvement of durian chips. Moreover, the findings strongly support the improvement method is essential for applications of QFD technique for design and development. It considered the importance of product design in technical requirements. This research supported an efficiency method for product research and design tool that considers the food production process, quality control, cost revenue and customer demands.
