The average creative brief fails for one of three reasons:

Too many objectives. 'We want to increase brand awareness, drive trial, improve brand perception, and generate leads.' That is four campaigns, not one. Each objective requires different creative, different media, different success metrics.

Audience defined too broadly. 'Adults 25–54 who drink coffee.' That is 80 million people with contradictory needs, values, and media habits. You cannot write to 80 million people. You can write to one person who represents the most valuable segment of that group.

Proposition that isn't single-minded. 'The best tasting, most convenient, most affordable option in the category.' Three propositions. Three campaigns. Choose one.

Every brief problem is a focus problem. Great briefs are acts of radical subtraction.

1. 1.The Business Problem** — Not the marketing problem. The business problem. 'We need to grow share among lapsed users' is a marketing problem. 'Our revenue is flat because our best customers buy less frequently' is the business problem that creates the marketing problem. Start here.

1. 1.The Target Consumer** — A specific person, not a demographic. Give them a name. Describe their day. What do they worry about? What are they proud of? What does this category mean in their life? The more specific and human this person is, the better the brief.

1. 1.The Single-Minded Proposition** — One sentence. One idea. Completable by the creative team into multiple executions. 'We're only #2. We try harder' is a proposition. 'High-quality, affordable rental cars with great service' is a product description.

1. 1.The Support** — Why should the consumer believe the proposition? Specific, verifiable proof. Not 'our customers love us.' Specific facts, demonstrations, or testimonials that make the proposition credible.

1. 1.The Desired Response** — What should the consumer think, feel, or do after experiencing this campaign? Not 'buy our product.' The emotional and rational state that makes buying likely.

1. 1.Tone Guidance** — 3 adjectives maximum. With examples of other brands or communications that express the desired tone.

Before submitting a brief to the creative team, complete this sentence:

'I want [TARGET CONSUMER] to feel [EMOTION] because they now understand [ONE THING ABOUT THE BRAND/PRODUCT] that they didn't understand before.'

If you can't complete this sentence cleanly in one breath, the brief isn't ready.

Examples:

'I want career-focused women in their 30s to feel seen and validated because they now understand that Dove thinks their natural appearance is more beautiful than the filtered version.'

'I want first-time car renters to feel confident because they now understand that Avis works harder for their business than the market leader.'

The single sentence reveals whether you have a brief or a strategy document masquerading as a brief.

Great briefs exclude:

Mandatories beyond the essential — Every 'must include' is a constraint on creative. 'Must feature the product in use, must show the logo in the first 5 seconds, must include a voiceover, must have a phone number visible' is not a brief — it's a shot list. Mandatories should be limited to legal requirements and genuine strategic non-negotiables.

The creative idea — A brief is not the place for the strategy team to pre-solve the creative problem. The brief defines the problem. The creative team solves it. Briefs that contain executional suggestions produce polished versions of the strategy team's initial ideas, which are rarely the best ideas.

Jargon — 'Leverage synergistic touchpoints to drive omnichannel brand affinity.' This means nothing. Write the brief in the language you would use to explain the product to a friend over dinner.

Ogilvy had a rule: if the brief couldn't be written in 24 hours, the strategy wasn't clear enough. Dru had a similar principle: disruption insight should be explosive — obvious once articulated, but invisible before.

Prolonged brief-writing is usually a symptom of unclear strategy, not thorough strategy. When you know the consumer, the proposition, and the reason to believe, the brief writes itself. When you don't know these things, no amount of additional brief-writing time will help. Go back to the strategy.
