Getting the Marketing Brief Right

Why the quality of the marketing brief still determines the quality of the work

In most client–agency relationships, everyone agrees that the brief matters.

As industry guidance has long recognised, “tightly written briefs, plus passionate briefing, equals engaged agencies, impactful campaigns and strong market results” (ISBA/IPA Best Practice Guide to Briefing).

It is the starting point for strategy, creative thinking and execution. A well-constructed brief aligns teams, clarifies objectives and creates the foundation for strong work.

Yet across multiple agency performance measurement programmes conducted by Observatory International, briefing consistently emerges as one of the areas where alignment can be most challenging.

This is rarely because teams underestimate its importance. More often, it reflects the realities of modern marketing, where multiple stakeholders, compressed timelines and evolving priorities can make clarity difficult to establish at the outset.

When this happens, even strong agency relationships can struggle to realise their full potential.

Why the brief matters more than ever

Today’s marketing environment is complex. Campaigns frequently involve multiple channels, specialist partners and rapid adaptation across markets and platforms.

In this environment, clarity at the start becomes even more important.

When briefs clearly articulate the objective, audience and desired outcome, agencies can focus their energy on solving the right problem. When that clarity is missing, time is often spent aligning expectations rather than developing ideas.

The most effective briefs focus on clearly defining the challenge to be solved, rather than prescribing the solution, giving agencies the space to apply their expertise.

Equally important is maintaining consistency once the brief has been agreed. While ideas will naturally evolve during development, significant changes to the brief can create misalignment, compress timelines and reduce the space available for creative exploration.

Over time, this can affect not only efficiency but also the quality of the work itself.

Learning from experience

Some of the strongest client–agency partnerships treat briefing as a core capability within the marketing organisation.

Across long-term performance measurement programmes, improvements in briefing are often one of the most effective ways to strengthen alignment and improve outcomes. This can include introducing more structured briefing frameworks, clearer processes and targeted training to support teams in developing higher quality briefs and providing more effective feedback.

The result is not only a more efficient process, but stronger alignment between marketing teams and agency partners, enabling agencies to deliver more impactful work.

Making briefing a strategic capability

Structured performance measurement helps organisations understand where briefing processes are working well and where improvements could strengthen collaboration and outcomes. By gathering feedback from both clients and agencies, it allows brands to identify where briefs may be unclear, where expectations are misaligned and where changes can improve the briefing process over time.
