What this dot point is asking
SEAB wants you to take a given design situation, which is usually a short paragraph describing a real problem, and turn it into a clear design brief. A good brief states the problem, names the intended user, and gives the purpose of the product. It sets the direction for everything that follows, so getting it right early saves you from designing the wrong thing.
The answer
What a design brief is
A design brief is a short written statement, often one or two sentences, that says what you are going to design, who it is for, and why. It is not a list of measurements; those come later in the specification. The brief is the headline of the project.
Reading the design situation
The situation is the raw problem. To turn it into a brief, look for three things:
- The problem or need. What is going wrong, or what does someone want to do but cannot easily?
- The user. Who has this problem? Their age, ability and circumstances matter.
- The purpose. What should the product let the user do?
For the situation "a commuter has nowhere safe to rest a drink on a crowded train", the problem is no safe resting place, the user is a commuter, and the purpose is to hold a drink securely while standing.
Writing the brief
Combine the three parts into a clear sentence that begins with a verb such as "design". A strong brief:
- names the user,
- states the purpose,
- and hints at one or two key requirements without locking down exact numbers.
Example: "Design a compact, secure holder that lets a standing train commuter rest a drink without it spilling or taking up much space."
Why the brief matters
The brief keeps the project focused. Every later decision, from research questions to the final test, points back to it. A vague brief such as "design something useful" gives you nothing to aim at; a focused brief tells you exactly what success looks like.
Examples in context
Example 1. A bag hook for a wheelchair. The situation describes a wheelchair user with nowhere to hang a shopping bag. A good brief is "Design a secure hook that lets a wheelchair user hang a shopping bag within easy reach without it swinging into the wheels." It names the user, the purpose and a safety requirement.
Example 2. A vague brief fails. A student writes "Design a useful kitchen gadget" and then cannot decide what to research. Rewriting it as "Design a one-handed gadget that helps a person with weak grip open jar lids" immediately makes research and ideas possible.
Try this
Q1. State the three things a good design brief should include. [3 marks]
- Cue. What you will design (the product or task), who it is for (the user), and the purpose (why).
Q2. Rewrite this vague brief to be useful: "Design a light." [2 marks]
- Cue. Add a user and purpose, for example "Design a clip-on reading light for a student to use on a top bunk bed without disturbing others."
Q3. From this situation, write a one-sentence brief: "Cyclists struggle to carry a water bottle on bikes without a bottle cage." [3 marks]
- Cue. "Design a secure, easy-to-fit holder that lets a cyclist carry a water bottle on a bike that has no bottle cage, within easy reach while riding."

Original5 marksRead this design situation: 'Elderly residents in a flat find it hard to carry several small items from the kitchen to the living room in one trip.' Write a suitable design brief for this situation.Show worked answer →
A suitable brief: "Design a lightweight, easy-to-carry product that allows an elderly person to move several small items, such as a cup, a remote control and medicine, from the kitchen to the living room in a single trip safely and without spilling."
What markers reward: a brief that names the user (an elderly person), states the problem or purpose (carrying several small items in one trip), and hints at a key requirement (lightweight, safe, no spills). It must be a statement of what to design, not a list of detailed measurements, which belong in the specification.
Original4 marksExplain why a design brief should name the intended user and the purpose, rather than just naming the product.Show worked answer →
Naming the user and the purpose keeps the whole project focused on a real need. The same product, such as a chair, must be designed differently for a young child than for an office worker, so the user shapes every later decision. Stating the purpose means you can later test whether the product actually solves the problem.
What markers reward: the idea that the user shapes design decisions (with an example), and that the purpose lets you judge success later. Simply naming the product is too vague to guide research and ideas.
