The brief is the campaign

There is a persistent idea that a loose brief respects creative autonomy. In practice it produces three rounds of revisions and a campaign nobody can evaluate.

What a good brief contains

• The commercial objective, in one sentence.
• How success will be measured, agreed before anything is made.
• The non-negotiables — legal, claims, exclusivity.
• Everything else, explicitly left open.

That last line is the one that gets missed. If you do not say what is open, creators assume nothing is.

Why this matters commercially

A brief that cannot be answered wastes the creator's time and the brand's budget simultaneously. It also makes post-campaign analysis impossible: if nobody agreed what success looked like, every result is arguable.
