I don’t have a serious term for this, but I’ll show a nearly finished pitch to one of our lead devs and do an “LOL” test. We’ll ask “Is what we’ve shaped doable in X weeks?” and if they laugh, it’s scope hammer time.
We use Airbnb’s X-star experience to discuss tradeoffs between appetite and constraints/boundaries. So a six-week appetite might get us a 3-star experience, but a 2-week appetite gets us a 1-star experience. Scope hammering is what we take out of the pitch (or call them stretch goals) to get to the desired appetite.
