A good brief does five things. It says what the work is for. It says who the work is for. It names a real budget. It names a real deadline. It names the person who can say yes on the client side.
The first one is the one most briefs miss. Production is downstream of strategy. If the brand strategy is unclear, the production will be unclear. We can help in both places, but we deliver better work when the strategy is settled.
Who the work is for is the second thing most briefs underplay. A campaign aimed at three audiences is a campaign aimed at none of them. We always ask for the single one. The brief that names that audience clearly is the brief that gives us a treatment we can build.
The budget is the part that gets the most awkward. The good brief names a real range and lets us tell you whether the ask fits. We cannot bid in the dark. We can bid against a number. If the number is wrong, we will say so before the treatment lands.
The deadline gets the same treatment as the budget. A real delivery date with the real review windows baked in. Production schedules collapse when reviews slip. Naming the chain of approvals up front lets us schedule against it.
The decision maker is the last one. We need to know who can say yes. Not who can pass the work to the person who can say yes. Briefs that route through three rounds of approval lose their edges. The work that ships best is the work that ships with the decision maker in the room.
