環境変化が激しいグローバルな競争下で,高品質な製品やサービスを安定して提供し続けるためには,製品実現のための業務プロセス(製品実現プロセス)の絶えざる改善が必須である.このために,従来,製品実現プロセスの仕組みの構築レベルを監査するISO9001監査や,仕組みの実行度を高頻度にモニタするプロセスQA(Quality Assurance)が実践されてきた.しかし,これらの取り組みは仕組みか実行のいずれかの評価・改善に重きを置いたアプローチであった.本報告では,我々が開発して来た品質経営評価技法に基づくプロセス改善手法を提案する.提案手法は,仕組みと実行の両面からプロセス品質を評価した結果を用いてプロセス改善対象を提示する.提案手法を社内のプロセス改善活動に適用した結果,プロセス改善を効率的に実施できることがわかった.

Continuous improvement of business processes for product realization (product realization process) is necessary to provide high quality products or services for customers constantly, under the global competition with severe change of business environment. For this purpose, ISO9001 audit for assessing establishment level of rules for product realization and process quality assurance for assessing performing level of those rules have conducted until now. However, those activities focused on improvements/assessments of either establishment level or performing level. In this paper, we propose a new process improvement method applying Quality Management System Evaluation Method that we developed. Our method guides improvement approach based on both evaluation results of establishment level and performing level of improvement target organization. We applied our method to internal process improvement activities and their results show that process improvements are achieved effectively using our method.
