T1: Design Criteria

Design Criteria are a list of things that your design solution must conform to. The word Specification is sometimes used instead of Criteria, but it means the same thing.

When writing your Design Criteria, you should try to avoid a rambling collection of bullet points. Your criteria should be informed from the research and analysis you have conducted during your exploration of the problem. Effective criteria are clear and concise but also contain relevant detail e.g. specific maximum height or weight etc. They must also be logically organised. Lastly, you must bear in mind that the criteria will be used at later stages of the project, firstly to evaluate the effectiveness of the designs you have devised and secondly to evaluate your final design and help you to consider further areas for development.

To help you - consider the following questions:

 

Purpose - what is the aim or end use of the product, environment or service?

Form - what shape/style must the product take?

Function - what must the product do?

User requirements - what qualities must the product have to make it attractive?

Materials and Components - what materials and components should be used to aid performance?

Size - what physical dimensions are required?

Safety - what factors need to be considered to make the product safe to use

Legal -what legal factors need to be considered?
