Recently have seen a video about the 5 why root cause analysis, which talked about a logic tree to find root causes and that was nice. Obvious, but nice to hear about.
Five why has very limited uses in practice when investigation root cause. I teach the basics of Five Why to staff so they can follow up low level incidents without my help, but I make sure to always review their findings.
If there is any meat to an incident I step in with proper root cause analysis like ICAM or TapRoot. With practice you can make short work of incident investigations for even smaller incidents that don’t warrant a significant investigation.
Sorry. I don’t know anything like that. The creator of TapRoot method used to provide newsletters talking about how/why he developed it, advantages over other methods, etc.
But I don’t know if he still does.
