Why Is My App SLOw? Defining Reliability in Platform Engineering • Jez Humble • GOTO 2023

You make it sound like the 2 sigma is deviation is something Google came up with by this is control theory concept is from the 1950s (i.e. en.wikipedia.org/wiki/Western_Electric_rules ). There are value here and enjoyed the presentation.

Thanks for providing a reference to the Western Electric rules and for your kind words about the presentation. I did not mean to imply that Google invented the idea of 2 sigma, that of course is just basic statistics (and I refer to its use in other domains). Rather, the application of this technique to platform reliability (and it's certainly possible other people have applied it here too)
