The lesson
Write the pass-or-fail line as one inequality early in the deck and spell out what happens on each side of it.
A Parks and Recreation marketing plan, rebuilt by Pitch Unfairly, states its goal as three boxes: Revenue, minus Cost, greater than a yellow ticket reading "$0". Below, "ABOVE $0" says the department survives and the town gets its festival back; "BELOW $0" says the department is eliminated. The cover reads "One weekend to prove Parks pays its own way."
Skip the sitcom props; the story and its numbers are invented. Keep the one-line success test with consequences on both sides, and name an audience you will not chase.
