Object-oriented databases for quality function deployment and Taguchi methods

Abstract In this paper, Object-Oriented Databases are proposed as being a new tool for Quality Function Deployment (QFD) and Taguchi Methods. Quality Function Deployment can help identify key product or process concerns with respect to customer requirements. Taguchi Methods, such as using Design of Experiments (DOE), can help identify what product or process relationships truly exist, their relative strengths and the nature of the relationship. In order to implement these two powerful quality control techniques for assuring that customer requirements are consistently met, a well organized information is required. Object-Oriented Databases are able to store, organize and manipulate both, the customer requirements and the product information for the performance of QFD and DOE.
