这个热电偶是从一个新的供应商那里采购的

Why#6a:WhywasanewspikeT/Cvendorbeingused.

为什么要从这个新的供应商处采购？Answer#6a:Reducedcosts.降低成本

Why#7a:Whywasn'tthisproblemanticipated?

为什么没有预料到这个问题？Answer#7a:Noguidelinesorproceduresforsuchchanges(nophysicalcomparisondoneandno“What-could-go-wrong?”analysis).

对这样的变更没有程序规定（没有做对比试验，也没有“可能会引起什么样的错误”的分析）“没有程序文件或检查表”是一个经常导致问题发生的根本原因。16D4:Definition&Verificatio17D4:Definition&VerificationofRootCauseWhy#5b:WhywastheT/Cpositionnotcheckedafterinstallation?为什么安装后热电偶的位置没有检查Answer#5b:Equipmenttechdidnotexpectanyproblem.设备侦探没有预期有任何问题。
