What this dot point is asking
Eduqas C600 expects you to turn a context and a user need into a design brief and a measurable design specification. You need to identify the primary user and wider stakeholders, carry out primary and secondary research including analysing existing products, and write measurable specification criteria. In the written exam this is tested by Explain questions on the brief-versus-specification difference and by tasks asking you to write measurable specification points.
Users and stakeholders
Designing well means thinking beyond the main user. A child's toy has the child as primary user, but the parent (safety, price), the retailer (packaging, shelf appeal) and the manufacturer (ease of making) are all stakeholders whose needs shape the product.
Research: primary and secondary
Analysing existing products is a key secondary method: studying products that already solve a similar problem to learn what works, what fails and where there is an opportunity to improve. Good investigation uses both: primary research to learn what your specific users need, and secondary research to learn from what already exists.
The brief and the specification
The brief is broad; the specification is detailed and testable. A good specification covers function, size, cost, materials, safety, aesthetics, ergonomics, sustainability and manufacture, and every point is measurable.
Try this
Q1. State one example of primary research a designer could carry out. [1 mark]
- Cue. An interview, questionnaire, observation, or measuring users (first-hand data).
Q2. Rewrite the specification point "the product should be cheap" so that it is measurable. [1 mark]
- Cue. "The product must cost no more than 10 pounds in materials" (a number to test against).

Eduqas C600 20192 marksExplain the difference between a design brief and a design specification.Show worked answer →
A 2-mark question, one mark for each clearly distinguished.
A design brief is a short statement of the problem and what is to be designed: it sets out the user, the purpose and the broad intention, often in a sentence or two.
A design specification is a list of measurable criteria the product must meet (size, cost, materials, safety, function, aesthetics), written so each point can be tested against the finished product.
Markers reward the distinction: the brief is the broad starting statement; the specification is the detailed, testable list of requirements. Treating them as the same, or describing only one, caps the mark at one.
Eduqas C600 20224 marksA student is designing a desk tidy for a school. Write four measurable points for the design specification.Show worked answer →
A 4-mark question, one mark for each measurable, testable specification point.
Suitable points (each must be measurable):
- Size: the desk tidy must fit a footprint no larger than 200 mm by 150 mm.
- Capacity: it must hold at least 6 pens and a 150 mm ruler.
- Cost: the materials must cost no more than 5 pounds.
- Safety: all edges and corners must be rounded to at least 2 mm radius (no sharp edges).
- Material: it must be made from a durable, easy-clean material suitable for a classroom.
Markers reward points that are specific and testable, with a number or a clear standard, not vague statements such as "it should look nice" or "it should be strong". Four vague points score poorly; four measurable points score full marks.
