5why与鱼骨图分析出的结果不一样，怎么办？
各位同行，发生质量异常，可以使用5why或者鱼骨图分析原因。但是5why与鱼骨图分析出的结果不一样，怎么办？ 例如：5why分析出的是A原因，但是鱼骨图分析出的是B原因，甚至，有的时候，原因A与原因B是相互冲突的(或相互矛盾的)。用鱼骨图找到可能的原因，针对可能的原因用5why深层次的挖掘根本原因，鱼骨图是锁定，5why是挖掘，两者之间的关系是这样，不矛盾不冲突。 噼里啪啦的静电 发表于 2024-9-19 21:30
用鱼骨图找到可能的原因，针对可能的原因用5why深层次的挖掘根本原因，鱼骨图是锁定，5why是挖掘，两者之间 ...
光靠鱼骨图你也锁定不了。
鱼骨图只能给你提供一个可能的方向。
要找到最有可能的方向，接下来最常用的办法是大家拍脑袋玩名义投票法
认真点的就需要数据分析以及DOE了 先鱼骨再5why {:1_180:} {:1_180:} {:1_180:} 噼里啪啦的静电 发表于 2024-9-19 21:30

有这样的问题说明你对常用的质量工具掌握不够，不明白每种工具的不同用法，建议加强学习。
fish-bone：
Brainstorm possible causes for analysis
Rank potential causes and determine high-potential for further study
Gather data to support or refute each idea circled
5 why
A fundamental principle of root cause analysis activity is that you must relentlessly continue to question conditions until you uncover those that are the primary contributors of the problem.Five-why diagrams are a visual representation of that thinking.
Using one of the primary potential causes identified in the earlier cause and effect diagram, the team uses a questioning strategy to drive deeper toward potential root causes.
The questioning strategy can, and often needs to, go beyond five levels.It may also split into multiple answers that creates multiple questioning trees.It is also possible that a stopping point will occur before five whys are reached.Any of these scenarios is acceptable as long as the result is a controllable potential cause that the team can investigate and correct.
学习学习 鱼骨图有可能会找出主要原因，5WHY探索根本原因吧:lol {:1_180:}
