This comment is for HN readers who might be interested in solutions. My two questions (a) and (b) were not rhetorical. Let’s get concrete. a) You are advising a company to “check b…

If you are interested in these ideas, you should know that this essay kicks off a series of essays that culminates, a year later, with an examination of the Amazon-style Weekly Bus…

And how are you going to tell that when you have a) variation (that is, every metric wiggles wildly)? And also b) how are you able to tell if it has or hasn’t impacted other parts …

I should note that this essay kicks off an entire series that eventually culminates in a detailed examination of the Amazon Weekly Business Review (which takes some time to get to …

This is accurate. https://xmrit.com/articles/gift-exceptional-variation/

What would you say if I told you Bryar has lots of stories of this style of thinking applied in early Amazon? This is pre-AWS Amazon, mind you — where they were trying to figure ou…

To be fair to OP, Wheeler never claims that for stable/in-control/predictable processes roughly half of the measurements will lie above the average. The only claim he makes is that…

So I've got a dumb question here: what happens when you use vanilla XmR charts with J-curve shaped or sub-exponential distributions? My current simplistic (and very dumb!) solution…

A couple of quick notes, from someone who has actually put this to practice — and in a non-manufacturing context, to boot! (From a brief reading of this thread, it seems like kqr, …

I believe you may enjoy this, which takes SPC methods and extrapolates from it an entire path to becoming data driven: https://commoncog.com/becoming-data-driven-first-principles/

Author here. Previous time this was on the front page: https://news.ycombinator.com/item?id=30930985 As an update, I temporarily relocated to a different city and spent four months…

Yes, rest assured the previous article talks about exactly this. (I mean, the title of this piece should give you a hint: “Pay attention to deviations from mainstream incentives” b…

Discourse is one of the best pieces of software I've ever used — I self-host, and it's never given me any problems. There's built-in backups to S3, I can upgrade the software 80% o…

This is actually predicted by the COR developmental model presented in the article. The terminology might be a bit wonky, but the basic idea is that ‘loss’ produces a stress respon…

> In response, some folk back into the weak form of the argument. The weak form is what you get when you hear someone say “history doesn’t repeat itself, but it rhymes” — that is, …

The problem is that Dr Ung walks back certain elements of his report, as is summarised in the final judgment: > the High Court found that the appellant had borderline intellectual …

I'd actually urge you to look into the details of the case — Nagaenthran had two psychiatrists and a psychologist evaluate him on separate occasions, each of them certifying that h…

Author here. Quite the contrary, actually — I’ve read all the above sources. On top of that, with the exception of Chambliss (which is a landmark work, to be clear), and Dreyfus (w…

I disagree with this assessment. (Or, more accurately, I’d like to see a more comprehensive counter argument). The article you link to is essentially a response to 2 pages in the b…

Readers who are interested in the actionable aspects of this topic should probably read the last instalment in this series: https://commoncog.com/blog/accelerated-expertise/ The ba…

This is an interesting question! The answer is to hold conclusions loosely and test; always test. One way to pick who to pay attention to is ‘believability’ — meaning that you list…

Ok, since I have to spell it out for you: I have not included any such theories because I have not found them useful. The links are to say something simple: my entire epistemology …

https://commoncog.com/blog/the-hierarchy-of-practical-eviden... I would ask the OP a simple question: what organisations have they built, and where are they now? Longer, but establ…

I would recommend the series first — AE assumes familiarity with the recognition primed decision making model (or RPD) which I cover in the series. If you want to read books to pre…
