The standard exists before the work does
Most teams decide what good means after the launch, in a retro, with the evidence already cold. Write the bar down first and it stops being taste. It becomes something a team can plan against and hit on purpose.
Our standard is published before you ever submit. Nine dimensions, the same anchor language for every product, applied against the stage you are actually at and not against a company with ten times your funding. No inspector moves past a dimension until the verdict can be defended against that language.
