How to write a creative brief: the 60-minute, step-by-step method

Writing a brief goes wrong when people start by writing. Start by answering, then assemble. This is the order that works, and it fits in about an hour for a normal project.

Step 1: Interrogate the objective (15 min)

Talk to whoever owns the business outcome. Ask until you can complete this sentence with a number and a date: "This work must ______ by ______." If the sponsor can't help you finish that sentence, the project isn't ready — say so now, not after three rounds of design.

Step 2: Choose the audience and their current belief (10 min)

Not a demographic card — a sentence: "[Who] currently believes [belief], and we need them to believe [new belief]." This one sentence does more work than any persona template, because it defines what the creative must change.

Step 3: Find the one message (10 min)

Write ten candidate propositions in five minutes, pick the one that is (a) true, (b) relevant to step 2, and (c) sayable in under twelve words. Kill anything two competitors could also honestly claim.

Step 4: List support — then cut it in half (5 min)

Reasons to believe the proposition. Three bullets maximum. Everything else belongs on a landing page, not in the creative.

Step 5: Separate real constraints from preferences (10 min)

Two columns. "Cannot change" (legal lines, brand marks, platform specs) and "would prefer" (tone, colour, previous campaign conventions). Creatives respect the first column and will — rightly — challenge the second.

Step 6: Name the approver and the dates (5 min)

One approver, in writing. Round-one review date, final delivery date, and what round one will be judged on (direction, not polish). This is the step that prevents the version spiral — see our client approval workflow guide.

Step 7: Write the brief (15 min)

Now assemble it, using the seven parts in our what-is-a-creative-brief guide. One page. If it doesn't fit on one page, you haven't made decisions yet — you've collected options.

A worked mini-example

OUTCOME:     300 trial signups by 30 June
AUDIENCE:    Small agency owners believe project tools are
             priced per seat and built for big teams; we need
             them to believe a planning tool can be flat-priced
             and built for teams their size.
MESSAGE:     "Plan campaigns like a big agency, pay like a small one."
SUPPORT:     Unlimited clients on one price · briefs, versions and
             approvals in one place · set up in an afternoon
CONSTRAINTS: Existing logo · UK English · accessible contrast
APPROVER:    [Founder] — round 1 on the 14th, judged on direction

The three mistakes to avoid before you hit send

Cc-ing the brief to everyone for "visibility". Send it to the approver and the makers. Commenters get a summary, not the document.
Burying the proposition in paragraph four. It goes under the objective, near the top.
Leaving the approval question blank. A brief without a named approver is a wish, not a brief. Our design brief template forces the question as #8 for that reason.

And the day after you send it, the useful question becomes: which version was approved, and when? CreativeBoard keeps the brief, every version and the sign-off as one object — built for lean teams. Early access is free:
