Vibe Driven Development
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. And most product orgs suck because they simply don’t use the products that they’re building; they ship incremental nothings without direction because they’re looking at spreadsheets all day long filled with junk data nothings.
