Build a one-page brand brief

The test of a brand brief is what someone can do after reading it. If they understand the colour palette but cannot tell which customer problem the business addresses, the document has preserved the wrong level of detail. A one-page format forces selection, so make that selection around decisions rather than presentation.

Include the information that changes the work

Begin with the offer and the audience situation. Explain the main need, the alternative a customer may consider and the meaningful distinction you can support. Use ordinary sentences, not a stack of abstract labels. A writer should be able to use the brief to reject an irrelevant headline, not merely repeat its vocabulary.

Add the central message and a few supporting facts. Include important boundaries, such as work the business does not undertake or a promise it cannot make. These limits are especially useful for a new collaborator who may otherwise fill gaps with assumptions from previous projects.

Show the voice in miniature

A short before-and-after example can communicate more than five tone adjectives. Explain why the revision fits. For a hypothetical maintenance service, a direct sentence about a delayed appointment may demonstrate the desired clarity better than the instruction ‘sound caring’. Choose a situation that colleagues regularly encounter.

Keep visual instructions proportionate. Link to approved logo files and any fuller design guidance rather than squeezing every specification onto the page. Distinguish mandatory elements from creative latitude. A designer needs to know which constraints are real and which examples merely illustrate a possible direction.

Make it a working reference

Include the document's date and the location of supporting information. If a claim depends on evidence, link to the evidence rather than turning the brief into an unsupported assertion. Mark unresolved decisions openly. A blank labelled ‘not agreed’ is safer than a polished sentence that appears approved but is still disputed.

Try the brief on a small task, such as a service introduction or a short partner description. Ask the collaborator which questions remain unanswered. If the missing answer would change the work substantially, the brief needs it. If it concerns a minor execution detail, it may belong in the project brief instead.

Keep the page readable at a normal size. Remove low-value material rather than shrinking everything to fit. The purpose is fast orientation and consistent decisions, not proof that a complex organisation can be summarised on a single sheet. When the business changes materially, revise the underlying decisions before adjusting the layout.

One way to test the selection is to remove each item in turn and ask what mistake becomes more likely. Removing the audience situation might lead to an inappropriate example. Removing a service boundary might create an unsupported promise. Removing a decorative phrase about ambition may change nothing. This exercise exposes which content is genuinely helping a collaborator make decisions and which content is simply customary in a brand document.

Keep project-specific requests out of the permanent brief unless they represent a lasting change. A campaign's deadline, channel and temporary offer belong in its own assignment. Mixing them into the brand reference makes the document expire unnecessarily and can cause a later writer to reuse a one-off promotion. Link the two documents so the collaborator can see the stable context and the current task without confusing them.
