In their "defense," this looks like another thinly veiled "look how are awesome tool solves problems, call now!" article and not a book in any fashion whatsoever.

We've enjoyed great success with the post-mortem templates in PagerDuty, which is part of their open-source incident-response-docs https://github.com/PagerDuty/incident-response-docs/blob/130...

Thanks for the question. Our experience is that the causal analysis method described in the eBook is a more effective way to understand the causes of a problem and find effective solutions. We often discuss the pros/cons of different RCA methods in our free webinars and we have one about Fishbone in June.

Since I had to look it up --

Root cause analysis, in the simplistic form, without a fishbone tree of events and failed controls, means that failure is inevitable. Again and again.

Edit: This document is actually cool: it uses RCA as a term and actually teaches failure analysis!

FMEA!
