RCA:Root Cause Analysis(根本原因分析)とは、事故や不具合が発生した際にその事象を引き起こした直接的な原因だけでなく、そうした事象を発生させるに至った真の要因にさかのぼって追求し、, 日本国内では、RCAの現場実践手法の一つとして「なぜなぜ分析」が広く知られており、これは「なぜ」という問い掛けを繰り返し行うことで、背景に潜む根本原因を探ってゆきます。今日、このRCAは医療、プラントはじめ様々な業界で導入されており、ものづくり企業の多くの現場でも適用されています。, 事故や不具合が発生した場合、その直接的要因として装置の故障といった偶発的な原因が考えられます。その場合は部品の交換などを行えば良いのですが、それ以外に操作ミスなど人にまつわる要因も存在します。作業ミスのような場合は、その作業者に注意を促すということでは真の対策とはなりません。, 人が行う業務手順はもとより、さらにはそうした運用を行っている組織の不文律・風土、人間関係といったところまで遡った分析を行い、真の根本原因を抽出する必要があります。, 人にまつわる要因といいますと、どうしても関係した特定の個人の責任を追及しがちですが、これでは真の問題解決にはなりません。人は間違いを犯すものであるという認識に立ち「上長のチェックを行うかどうかが、あいまいな手順になっていないか」「情報を伝えるタイミングは適切だったのか」など、業務ルールなど, 「新人で仕事を熟知していなかったから」というのは状況説明をしているに過ぎず、作業教育をしていなかった、あるいは作業マニュアルの記述が不十分だったなどが原因になるでしょう。, 根本にある原因は一つとは限りません。複数の原因があたかも木の根をはるように存在していると考え、要因の深掘りをしてゆくことになります。このような追求を進めてゆくと自ずと「結果」-「原因」といった連鎖になってゆくはずですが、, 対策は、個人の努力などあまり人に依存する内容にすると、守られなくなりがちです。従って「注意する」「努力する」というような精神論やあいまいな表現ではなく、, なぜなぜ分析をはじめRCA分析は体系づけられた理論ではなく、詳細手順なども業界や製品・システムの性質などに即し、各社で工夫しながら運用されています。しかし基本となる考え方や留意点は共通することが多いので、実践活動を通じた適用を心掛けていかれると良いでしょう。.
