近年,コストと納期の制約の下で高品質な製品・サービスを安定して提供し続けるための品質マネジメントの重要性が増している.このような背景の中,我々は,製品開発の業務プロセス品質を事業部門の「仕組み」と製品開発プロジェクトの「実行」の両面から評価し,ベストプラクティスを提示し改善提案を行う品質経営評価技法を開発し実践してきた.今回の報告では,有効な改善提案を提示可能にすることを目的として,ベストプラクティスの表現方式を検討し,ベストプラクティスライブラリを構築した.それを用いて事業部門に行った改善提案は75%が採用され,構築したベストプラクティスライブラリは有効な改善提案に結び付くことが検証できた.

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.
