Abstract
Recently, quality management has become more important to provide high-quality products and services, under the constraints of cost and delivery time. In this situation, we have developed and applied the Quality Management System Evaluation Method, that assesses both establishment level of processes in business unit and performing level in each product development project, and provides best practices as process improvement proposals. In this paper, we designed a description method of best practices, and established best practice library. Moreover, we confirmed that the established best practice library could provide effective process improvement proposals for business units, as 75% of process improvement proposals were actually accepted by the business units.
