Before a designer opens a sketchbook, someone has to answer a few basic questions. What are we making? Who is it for? What problem does it solve? What are the constraints? The design brief is the document that captures those answers. It is the contract between a client and a designer, though it does not have to be long or formal. A single page can be enough if it is clear.

A useful brief covers the project's background, objectives, target audience, deliverables, budget, timeline, and any mandatory elements like a logo or brand color. It also states what success looks like. Without that, the designer is guessing. Vague briefs produce vague work. When a client writes make it pop, the designer has nothing to work with. When a client writes the audience is first-time homebuyers aged 25 to 35, and the goal is to increase mortgage applications by 15 percent, the work has direction.

What a brief should include

• Background and problem statement.
• Goals and measurable objectives.
• Target audience and context.
• Deliverables, timeline, and budget.

A good brief is a conversation starter, not a straitjacket. It should be specific enough to guide decisions and flexible enough to allow the designer to propose something unexpected.
