Abstract
In order to perform the planning and the designing new products based on the customer requirements (CR) accurately and systematically, we had developed QFDNavi^<TM> to support QFD (Quality Function Deployment) process, which relates the CR to the engineering metrics systematically. To set up the design target specification based on the CR, we introduced the evaluation method of the cost-weight (importance rating) and of the customer satisfaction (CS) impact. Using these methods, we did the quality deployment efficiently and improved the design quality. Consequently, we verified the validity of this method equipped with the function that reduces QFD errors and that navigates QFD activity, and this tool is utilized in many internal projects.
