Estimating is useful for: * getting an idea if something is worth doing * picking between things that are equally valuable but may be differently expensive * rejecting things that are estimated to take months, as that means we have no idea and need to break it down more * making the scope more explicit Estimating is not useful for: * planning a release date for the thing you haven't started yet
