      ...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?

      in my time on AWS -- six years, at small startup and at Lyft -- I believe that the ability to learn from AWS operational excellence, robustness, resilience would have benefited me substantially more than dunno, improvements in CloudFormation...

      I'm planning to talk in even more detail on how we did incident management and analysis, but I don't think we're going to get into a public example of an actual event. Our analyses are thorough and typically include many internal confidential systems and details.

          Details about how an actual event was analyzed is valuable (by who? over what time period? who did they speak to, what behavioral data did they collate with verbal data? what background or history did they incorporate into the themes or patterns they arrived at?)

          (what training is provided for people doing the analysis? if group meetings are involved: are they optional or required for some/all to attend?) Those sort of things are worthwhile to hear about in your presentation, details of the event itself is less interesting to me.

          > typically include many internal confidential systems and details Makes sense but I think there would be *huge* benefit to your customers if there was a way to make this work. For reference one of the better postmortems from industry recently:https://blog.cloudflare.com/details-of-the-cloudflare-outage-on-july-2-2019/ …

          request as a former and (almost certainly) future AWS customer: consider "typically include many internal confidential systems and details" as a challenge rather than a hard blocker
