Abstract
In order to sustain providing high quality products and services, it is essential to improve the processes producing them. We developed a prototype of quality management system evaluation method that can evaluate quality of product development processes, identify the weak points, and guide the improvement actions. In this paper, basic concepts and details of the method such as its questionnaires, input items, quantitative evaluation procedure, output forms to facilitate improvement actions, are described. Moreover, we address the results of feasibility verification by applying to seven piloting business units.
