Small sample sizes reduce precision of estimation. Try to acquire more data but avoid simply adding “more of the same” as obtaining lots of small samples from the same population will not help. Applied more broadly: seek different opinions to avoid confirmation bias.

The devs, test, suppprt, PMs are most important in the next 60 seconds. Because they are in the front line. Not you.

60 seconds

As the CTO you are not important in the next 60 seconds. Dev fixing bugs, writing a line of code, support helping a user, PM holding a project meeting are all more important than you.

It’s hard to stay humble when everyone laughs at your jokes. But you are probbaly least important person in the IT organisation in the next 60 seconds.

A trough back to my trading platform days…

What happened was truly a black swan as I can assume algo after algo saw their EURCHF 1.1999 stops hit, and moments thereafter the EURCHF pair crashed to less then 0.75, margining out virtually every single long EURCHF position, before finally rebounding to a level just above 1.00, which is where it was trading just before the Swiss National Bank instituted the currency floor over three years ago.

Over two decades ago, George Soros took on the Bank of England, and won. The SNB took on virtually every single macro hedge fund, the vast majority of which were short the Swiss Franc and crushed them…

Testing the initial appeal and actual usage of a potential new product by simulating its core experience with the smallest possible investment of time and money.

Cheaply test your thinking “build it, and they will come.” Learn from it as fast as possible. Think 1 PowerPoint slide, single page website, $100 AdWords campaign, product packiging/logo… search Pretotyping for examples.

I think of pretotyping as minimum-viable MPV ie MVMVP. Does sound like an acronym hell but you what I mean.
