The brief is already the problem

At some point in the last decade, the agency brief became a document of certainty. It describes the audience. It prescribes the channels. It specifies the deliverables, the timeline and occasionally – fatally – the creative direction. By the time it lands in an agency’s inbox, it has usually been reviewed by four people, approved by two, and shaped by an organisational preference for appearing decisive. It has also, in most cases, already solved the wrong problem.

This isn’t a failure of effort. The people who write briefs work hard on them. The problem is structural: the brief is the output of an internal conversation that happened without the outside perspective that would have made it useful. By the time an agency is involved, the strategic questions have already been answered – not by the wrong people, but without the distance that answering them well requires.

The result is predictable. Agencies produce work that answers the brief precisely and misses the point entirely. Leaders are disappointed but can’t say why, because the work delivered exactly what was asked. The campaign underperforms. The relationship frays. Another brief is written.

There’s a coherent logic behind this. Engaging an agency with an open-ended problem feels expensive and risky. Better to do the thinking internally, arrive at a clear direction, then commission execution against it. It keeps control in-house and produces something that can be compared across agency responses.

The catch is that strategic clarity about your own organisation is hard for any team to achieve, however capable. It takes external perspective, competitive intelligence and a kind of honest assessment that is genuinely difficult to conduct about yourself.

This used to be a resourcing problem. It isn’t anymore. With AI, a competitor scan, a customer-language audit or a positioning gap analysis can be produced in an afternoon. What hasn’t become cheaper is knowing which question to ask. AI will faithfully answer “are we perceived as premium enough?” if that’s the brief. It won’t tell you that premium perception was never the actual gap. The people closest to an organisation aren’t short of information anymore. They’re too close to notice which of their own assumptions the information-gathering was built around.

So the brief gets written based on internal assumptions. The agency responds to those assumptions rather than questioning them. The work is optimised for internal approval rather than external impact. And everyone wonders why it didn’t move the needle.

Here’s what a brief looks like when the problem has been pre-solved incorrectly:

We need a campaign that repositions us as a premium brand in the SME market, using video-led content across LinkedIn and Instagram, with a focus on our new product feature set.

This brief contains at least four assumptions that haven't been tested. That the positioning problem is about premium perception rather than, say, category relevance. That SMEs are the right audience rather than the specific buyers within those businesses. That video is the right format for the message being delivered. That the product feature set is the right strategic hook rather than the outcome those features enable.

None of these assumptions are interrogated. They arrived because someone in a planning meeting said them with enough confidence, and they hardened into requirements. This is easier to miss than ever, because the brief may well be AI-assisted – clean, well-researched, confidently sourced. That polish makes untested assumptions harder to spot, not easier. A well-produced brief and a well-diagnosed brief are not the same thing, and the difference has never been less visible.

An agency that takes this brief at face value will produce a video campaign about product features. It will be well made. It will not work. An agency that pushes back on the brief – that asks what evidence suggests premium perception is the gap, what a converted SME buyer looks like, whether product features are actually the decision driver in this category – risks being seen as difficult, and may not win the pitch.

The organisations that get the most from agency relationships structure them differently. They involve external strategic thinking before the brief is written, not after. They treat the brief as a hypothesis to be pressure-tested rather than a specification to be executed. They distinguish between the strategic question – what is the real problem we’re trying to solve – and the executional question, which follows from it.

This doesn’t mean the brief disappears. It means the brief earns its certainty rather than asserting it. A brief that has been stress-tested by someone outside the building, that has had its assumptions examined and its logic challenged, is worth executing against. A brief that is certain because no one questioned it is a liability.

So before the next brief goes out, ask the one question it can’t answer for you: how do we know this is the right problem?

If the answer is "because we discussed it internally and agreed," that’s not an answer. That’s how the wrong problem gets solved efficiently, at significant expense, every time.
