This comment is what PKL is going to be remembered for. Tbh I wouldn’t even have the courage to write the comment myself as the framework was coming from Apple.
Designers should understand design, engineers should understand function - and PMs should understand the market. For instance why should we prioritise one segment over the other? How should we price the product? What are the second order effects of prioritising one feature over the other?
This often involves human ingenuity instead of software. One of the best examples of an MVP is Zappos, where the founder went down to a local Footlocker and took photos of all the shoes. He then uploaded them to his blog, added some margin on the price and had a buy button which emailed him whenever anyone clicked it. He’d then just run down, buy the shoe, add ship it over to the buyer.
A simple blog was turned into a e-commerce MVP and his idea was slowly validated.
