For complex products, product development may take a long time. Late delivery and customer dissatisfaction may be inevitable if product quality is not assured from the beginning of the development. The aim of this study is to propose a method to monitor such product development projects from the viewpoint of product quality as well as schedule and cost. The method proposed is built mainly upon Quality Function Deployment (QFD). QFD is already a frequently used approach in relating customer needs to product and process parameters and prioritizing the critical success factors. With the extension that we propose, QFD is used also in predicting customer satisfaction rates by collecting certain realization information throughout the product development. This extension integrates a modification of RAPIDO product maturity assessment method with QFD. At each phase of the project, project managers are able to see the technical requirements fulfillment and customer satisfaction indicators, and compare them to planned ones, so that they can prioritize the tasks accordingly. This method is expected to be useful especially for industries in which development phases may take several years. A hypothetical application of the proposed method in defense industry is presented. Directions for future research are provided.
