How to write a marketing brief people can act on
A brief is a decision record, not a wish list. Here is a structure that answers the questions a strategist or designer will ask on day one.

What should a brief contain so the first round of work is usable?
Start with the business decision
Most weak briefs begin with the deliverable — 'we need a new campaign'. Start one step earlier: what will change in the business if the work succeeds? A new product reaches its first 200 buyers; trial requests replace cold calls; a price increase is accepted without churn. That sentence decides everything downstream.
Write the brief in seven parts
- Objective — one measurable business outcome and a date.
- Audience — who must act, what they believe today, what they should believe after.
- Single message — the one thing to remember. If you have three, rank them.
- Proof — facts that make the message credible, and which ones you are allowed to publish.
- Mandatories — logos, legal lines, offers, channels already booked.
- Budget and timing — working and media budget separately, plus fixed dates.
- Approval — who signs off, and who is only consulted.
How to judge whether it is ready
Give the brief to someone outside the project and ask them to explain the task back in two minutes. If they describe a different audience, objective or message, the brief is not finished. A second test: can every line be checked against the finished work? 'Modern and bold' cannot; 'readable on a phone at arm's length' can.
Common gaps
- No current-state description, so nobody knows what to change
- Budget given as a single number mixing media and production
- Several decision makers with no final approver
- Claims with no proof the team can verify
