8D手法(D0〜D8)の一部です。
D0 準備
D0 は8Dプロセスの準備段階です。
目的 - 問題を特定し、8D開始の必要性を評価 - 緊急度と影響範囲を評価 - 拡大防止のための緊急措置
主要アクション 1. 問題特定: 現象、時期、影響を確認 2. 緊急対応: 安全/規制問題の即時封じ込め 3. 開始準備: 背景情報収集、チーム編成準備
成果物 - 問題予備記述 - 緊急行動計画 - 経営陣の開始承認

The 8D (Eight Disciplines) problem-solving methodology is the global standard for quality engineering under IATF 16949. It guides teams through D0 (Preparation and Emergency Response), D1 (Cross-Functional Team Formation), D2 (Problem Description using 5W2H), D3 (Interim Containment Actions), D4 (Root Cause Analysis), D5 (Permanent Corrective Action Verification), D6 (Implementation of Corrective Actions), D7 (Recurrence Prevention), and D8 (Team Recognition and Closure). Each discipline provides a structured approach to identifying root causes, implementing effective solutions, and preventing recurrence.
