The brief agencies actually need

Key points

  • The most useful part of a brief is what is deliberately excluded.
  • Name one objective, not five, or you will get work that serves none.
  • Approval routes belong in the brief, not in the first review meeting.

Agencies deliver against what they are told. When the result disappoints, the cause is more often the instruction than the execution.

The eight questions

1. What is the business problem? Not "we need a campaign" but "enquiries from the north of the region have halved since a competitor opened".

2. What should happen? One measurable objective with a number and a date. "300 enquiries by the end of November" is an objective. "More visibility" is a wish.

3. Who exactly? Not a demographic sketch. A description of the person, their situation, and what they are currently doing instead of buying from you.

4. Why you? The single reason a customer should choose you. If you cannot name one that a competitor could not also claim, that is the real project.

5. What must appear? Legal requirements, mandatory claims, the logo, the guarantee, the phone number.

6. What must not appear? This is the most valuable section and the one usually left out. Colours you have rejected before, tone you dislike, claims your legal team will block, imagery your industry has exhausted.

7. What exists already? Brand guide, photography, previous campaigns and how they performed, existing materials that must remain consistent.

8. Budget, deadline, approval route. The real budget, not a fifth of it. Who approves, in what order, and how long each stage takes.

Withholding the budget to get a better price is the most expensive habit in the industry. You get proposals you cannot afford and pay for the rework.

What a good brief refuses to do

It does not propose the solution. "We need a video campaign on social" is an answer, not a brief, and it removes the reason for hiring anyone.

Describe the problem and the constraints. Let the proposal come back with the channel.

Approval is a project risk

ApproversTypical delayEffect on work

Name one decision-maker with the authority to say yes. Everyone else advises.

Test the brief before sending it

Give it to a colleague who has nothing to do with the project. Ask them to explain back what is wanted, who for, and by when. If they cannot, the agency will not either.

Frequently asked questions

How long should a brief be?

Two pages. Longer briefs are not read; shorter ones leave too much to invention.

Who writes it?

The client. An agency writing its own brief is being asked to mark its own work.

Splitting an ad budget: the 70-20-10 rule

Seventy per cent on what works, twenty on scaling, ten on experiments. The rule is old, simple, and violated in almost every account.

Positioning before the first ad runs

Advertising amplifies whatever you already are. If that is indistinguishable from four competitors, the budget amplifies the confusion.
