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 back after a certain period”. After the certain period, they

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 because of a) an NDA, and b) it took some time to test it in

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 out how to build e-commerce web software at scale, from scra

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 97% of all data points for a stable process (assu

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 that I've used for power-law type distributions —

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” because the mainstream incentives in F&B are just so, so

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% of the time from a web interface (even on my p

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 response. In other words, if you passionately pursue a project, on

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 functioning; not that he was suffering from mild intellec

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 book, where Hoffman et al mention, almost in passing, that CL

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 listen to those with at least 3 successes, and a coherent explan
