Campaign brief: how to write a brief that works

Challenge, insight, idea, role of the brand, role of media, KPIs: the skeleton of a creative brief and the questions each section has to settle.

Updated October 6, 2026 · MAPS editorial team

In brief

The campaign brief is the short document that hands the strategy over to the people who will create the campaign. A solid skeleton has six parts: the challenge to solve, the insight about people, the strategic idea, the role of the brand, the role of media and the KPIs to measure it by. A good brief is short, makes choices and says what must not be contradicted.

The six parts

Challenge — the business or marketing problem, written as a tension to resolve, not as a numeric target.
Insight — a truth about people that unlocks the challenge: a behavior, a belief, a contradiction. Not a fact about the brand.
Idea — the strategic platform the executions will spring from. It isn’t a tagline or an ad yet.
Role of the brand — what part the brand plays in people’s lives, within that idea.
Role of media — how and where the idea needs to show up, with the channel choices justified.
KPIs — how we’ll know it’s working: business, brand and behavioral measures.

How to write it

1. Write the challenge as a tension

“Grow 10%” is a target. “We have to convince people who see us as cheap that we’re worth full price” is a challenge: it says what has to change in people’s heads.

2. Find the insight with evidence

An insight rests on signals: customer quotes, observed behaviors, data. A well-written tension is often the best starting point.

3. Frame an idea, not an ad

The idea has to be able to live across several touchpoints. Try describing two or three ways it could show up in the world: if it only works in a TV spot, it’s an execution.

4. Assign roles to brand and media

The role of media isn’t a list of channels: it’s a pattern of presence. For each chosen channel, one line on why.

5. Choose KPIs that measure the challenge

Every KPI should say something about the original challenge. If the challenge is perceived price, click counts aren’t enough.

6. State constraints and assumptions

What the brief can’t contradict (essence, positioning, excluded markets) and what it takes as true without having proven it. Assumptions must be checked before production.

An example. A fresh pasta brand, “Sfoglia d’Oro.” Challenge: supermarket shoppers see fresh pasta as a Sunday luxury. Insight: on weekdays, people look for something good that takes no more than ten minutes. Idea: fresh pasta as a shortcut, not a celebration. Role of the brand: the ally of Tuesday-night dinner. Role of media: presence close to the moment of decision, in the evening. KPIs: weekday purchase frequency, brand association with quick dinners.

The most common mistakes

Too long. A ten-page brief doesn’t give direction: it scatters it.
An insight about the product. “Our product is handcrafted” isn’t an insight about people.
Competing objectives. One campaign, one challenge.
KPIs disconnected from the challenge. They measure activity, not change.
Hidden assumptions. Whatever isn’t proven should be written down as such.

How MAPS does it

In MAPS the Campaign Brief Skeleton is one of the thirteen Strategic Flows in Pro Mode, in the Activate phase, alongside Content Pillars. It works on what you select on the canvas or on a suggested scope, and builds the six sections — challenge, insight, idea, role of the brand, role of media, KPIs — with the points not to contradict, the assumptions to verify and the most fragile section. The flows are chained: a brief written after the positioning and the Message House starts from choices already made. With “Promote to canvas” it lands on the Strategic Flows page.

Frequently asked questions

How long should a creative brief be?

As short as possible: often one or two pages. If you need more room, there are usually choices missing.

What’s the difference between an insight and a data point?

The data point says what’s happening; the insight explains why people behave that way, and opens a possibility for the brand.

Who writes the brief?

Usually the strategist or the client’s marketing team, but it should be discussed with whoever will make the campaign: a brief the creatives don’t understand doesn’t work.

Is the idea in the brief already the campaign?

No: it’s the strategic platform. The campaign is one of its possible executions.
