Here is something I have observed consistently across 37 years in agencies, across good markets and difficult ones, across categories and budget sizes: the brief is rarely a description of the problem. It is a description of the solution the client has already settled on.
Marketing teams form a view internally before the agency conversation starts. That is how organisations work. By the time the brief reaches you, there has already been a leadership discussion, a budget decision, and usually a direction. What the agency is being asked for is validation and execution, not diagnosis.
The pressure behind this is real. Marketing teams are expected to move quickly and arrive with answers. An open, diagnostic brief can read internally as indecision. So a position is formed, the brief is written to support it, and most agencies take it from there.
The problem with executing the brief
“We need a digital campaign targeting 25–45s.”
“We want to increase brand awareness.”
“Our competitor is outspending us on TV and we need to respond.”
These are not briefs. They are instructions.
When an agency executes an instruction without interrogating the premise, two things tend to happen. The campaign is well executed. And it does not move the business.
Agencies default to execution for understandable reasons. Clients value responsiveness. Pushback can be misread as friction. And if your commercial model is built on throughput, there is little incentive to slow things down and ask harder questions.
But there is a cost to that dynamic. Clients rotate agencies every few years because outcomes plateau. Agencies lose pitches they expected to win and struggle to explain why. In many cases, the issue was never the execution. It was the brief itself.
What is usually missing
In my experience, most briefs fall short in three areas.
First, the real business problem. A request for brand awareness may actually mask a conversion issue, a pricing constraint, or a distribution gap that no amount of media weight will solve. If the agency does not ask, it will not know. If it does not know, it will optimise the wrong outcome.
Second, honest commercial context. What does success actually need to deliver? Not the stated KPIs, which are often proxies, but the real business pressure behind them. Revenue, margin, market share, timeframe. Without that context, strategy is calibrated to the wrong target.
Third, what has already been tried. Clients rarely volunteer this. Briefs tend to look forward, not back. But understanding what has not worked—and why—is often the fastest path to what will.
This is not a client failure. It is a failure of the briefing process. And it is exactly where a good agency relationship should add value.
Why structure matters
The network agency model is built for scale. That is its strength, and in this context, its constraint. Trading models, inventory positions, and holding company economics create a bias toward speed and volume. The system is designed to take the brief as given and move efficiently to execution.
Independent agencies operate with a different set of incentives. The commercial outcome is simpler: the client’s business either improves, or it does not. There is no structural buffer if performance falls short. The relationship is the asset, which means getting the diagnosis right matters as much as getting the execution right.
This is not a question of intent or effort. It is structural. Incentives shape behaviour, and the two models are built differently.
What good looks like
A brief should be treated as a starting point, not a contract.
The agencies worth hiring approach it as a hypothesis to be tested, not a specification to be delivered. They bring questions into the first conversation before they bring answers. They challenge when the stated problem does not align with the evidence, and they do it with enough commercial grounding to be useful rather than obstructive.
That requires a different kind of relationship. One where challenge is expected, not managed. It takes more trust, but it produces better outcomes.
An invitation
If you are reviewing your agency, or considering a new one, there is a simple question worth asking:
Does your agency ask better questions than you do?
Not more questions. Better ones. The kind that uncover the business problem beneath the marketing problem, and give you confidence in the strategy before a dollar is spent.
That is the standard worth holding agencies to. It is certainly the standard we hold ourselves to at Media Republic.
The brief is almost never the real problem. But it is almost always where the real problem hides.
