This describes how I iterate on The Session:
It comes down to this annoying, upsetting, stupid fact: the only way to build a great product is to use it every day, to stare at it, to hold it in your hands to feel its lumps. The data and customers will lie to you but the product never will.
This whole post reminded of the episode of the Clearleft podcast on measuring design.
The problem underlying all this is that when it comes to building a product, all data is garbage, a lie, or measuring the wrong thing. Folks will be obsessed with clicks and charts and NPS scores—the NFTs of product management—and in this sea of noise they believe they can see the product clearly. There are courses and books and talks all about measuring happiness and growth—surveys! surveys! surveys!—with everyone in the field believing that they’ve built a science when they’ve really built a cult.
