欢迎来到8D（8 Disciplines）课程，福特汽车公司使用8D作为问题解决的方法（见QS-9000要求之4.14.1.1）。当福特的供方具有零件或过程的问题时，福特要求供方完成8D过程以确定根本原因并实施纠正措施。
背景：

供方的8D报告必须回答下列问题
问题是什么? (D2) 问题如何解决? (D3至D6) 将来该问题如何预防? (D7)
顾客将通过确认8D报告来决定这些问题是否已经回答：
对零件的知识进行了充分论证。 完全确定了根本原因并聚焦于该原因。 遗漏点已经被识别。
确定与根本相匹配的纠正措施。 纠正措施计划的验证已经被确定。 包括了实施纠正措施的时间计划。
有证据显示供方将把纠正措施纳入整个系统。
