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.

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.

Consulting. I’ve done a little bit of it before as an occupational hygiene consultant. In a 2 week period I’d done air quality tests at a sulphuric acid processing plant, noise dosimetry at a bread factory, management system audit at Shell petroleum, and reviewed findings of air quality tests at a building where half the workers were “getting sick all the time”.

But it’s not consistent work, and if you go into business for yourself; 1- good luck finding the work, and 2- have fun spending months chasing up invoices.

Well this is just off the top of my head, but… bribe the captain with beer and cooking.
