I think the interesting question here is: if we understand that product validation frameworks are half process and half taste, and the taste bit is under-discussed (because it’s tacit, etc) then what have believable product people said about developing taste?
Next week’s post will be about this — I have a pile of articles that I’ve been collecting over the past decade, so we can at least do slightly better than ‘live it and notice it intentionally’ — as @kirso puts it. (Though in practice a huge chunk of getting good at building products is still going to be ‘live it and notice it intentionally’).
Edit: Also: I’m beginning to think that a huge chunk of my writing is just ‘what is tacit and stuck in people’s heads?’ Because that nearly always happens to be under-discussed.
