Part of the 8D methodology (D0–D8).
Discipline 3 (D3) 是 8D 流程的防御墙。ICA 是旨在根因调查期间保护客户免受问题影响的临时措施。
1. 围堵策略 与 D0 中的反射性动作不同,D3 是一个经过规划的策略。它必须是: - 已验证:在全面实施前证明有效。 - 已文件化:记录在作业指导书中。 - 临时性:始终打算被永久纠正措施 (PCA) 所取代。
2. 围堵的广度 稳健的 D3 必须进行上下游排查: - 在制品 (WIP):清理所有机器和组装工位。 - 仓库:筛选成品库存。 - 运输中:如果风险足够高,拦截货车或货船。 - 现场:与客户协调,隔离其设施内的库存。
3. 清断点文档 D3 最关键的产出之一是“清断点” (Clean Point)。这是第一个保证经过 100% 检验且无缺陷的序列号、日期代码或批次。必须立即将此点告知客户。

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.
