      I’ll lay out my experience and thoughts on this topic with more detail and respect, so apologies for the short dismissiveness for now. I don’t think why/how matters, it’s what goes with it. I also think events and causes can be reconstructed to an underestimated degree.

      The dismissiveness on these topics and perspectives is something I’ve heard from others at Amazon, although I’m unsure if there is a connection there.

      I suspect there is a connection. Amazon values operational excellence very deeply, but we don't share a lot of our culture and lessons. It may be hubris on our part, but we also think we have a very strong record ...

      ... at the same time, we see some advice that we've tried and seen fail, or criticisms of approaches we know work. I'm planning to share much more in an upcoming talk!

      I’d encourage the sharing of the actual details of incident analysis at Amazon, then. The “5 Whys”, in the end, is a method (however implemented) to collect data. We can debate the common/unique implementations of methods...

      ...but without the details of what data is gathered and how it’s analyzed, these debates are unhelpful at best. I keep hearing Amazon doesn’t perform these analyses in the skeletal/linear “5W” way...great! Now show me what you actually do, then.

      The question I would ask is can any of this be shared publicly? If not, what are the blockers?

      The answer to why Amazon does or doesn't anything is basically always "Will doing this benefit our customers more than other ways we could be spending the same effort?".

          my hypothesis would be that for many AWS customers, seeing how AWS runs "operational excellence" *including ground truth of incident postmortems* would be *incredibly valuable* and the effort... it doesn't involve any code, at least?
