Questions from this subtopic
Each one with the model answer underneath.
- 1
What is a client in product design?
Model answer
A client is the person or organisation a designer works for, who sets the need and approves the solution. A client may be different from the end user of the product.
- 2
What is an end user?
Model answer
An end user is the person who will actually use the finished product. A stair-lift controller has an elderly homeowner as its end user, even if a care provider is the client.
- 3
Why must a designer consult the client throughout a project?
Model answer
Regular consultation keeps the design matched to the client's real needs. Early feedback avoids costly changes late in development.
- 4
How can a designer identify a genuine problem or need?
Model answer
A designer can observe people, interview potential users and study how existing products fail them. A genuine need is one that real users confirm, not one the designer assumes.
- 5
What is a design brief?
Model answer
A design brief is a short statement of the problem, the intended users and what the product must achieve. The brief sets the direction for research and ideas.
- 6
What should a good design brief include?
Model answer
A good design brief names the problem, the client or end user and the context of use. A good brief also states any major constraints without prescribing a solution.
