UPDATED DESIGN CRITERIA
Now that you have one idea you will be ready to add to and refine your design criteria to that they are more thorough, detailed and measurable.
​
'The Design Criteria' is also referred to a 'master list of technical requirements' but this can get easily get confused with '1.6 Technical Specification' and so we call it 'Design Criteria'. This falls under two mark scheme bands, both 1.3 & 1.5. To quote OCR this section (1.3 & 1.5) should show:
​
'A range of comprehensive requirements are identified that offer scope to support the design process
Requirements that the investigations reveal are added to the candidates master list of requirements, with explanation'

A reminder - What is Design Criteria?
This is a list of specific criteria (or goals) that a product must meet in order to be successful. You will be testing and evaluating your final design and prototype against these. They must also be specific and measurable if possible.
​
Often the list considers aspects within each of these categories:
User / Target Market | Functionality | Materials | Aesthetics | Cost (value) | Ergonomics
Environment (literal) | Sustainability | Reliability | Health and safety considerations | Size / Weight
​
How can we define these?
Think back to the anglepoise example we created as this was at a level we would expect to see at this stage.
Now over to your own criteria...
-
What have you discovered since you you last write your criteria?
-
How does the design idea you are developing help you refine these further?
-
Make these more specific and measurable (eg weight, sizes, materials, strength, lumens)
-
Let feedback from users stakeholders guide these decisions - don’t just make them up.

Checklist & Markscheme
-
Do you have a list of requirements that your product must fulfil? Including technical and performance requirements
-
Does your Design Criteria evolve throughout your NEA?
-
Do you justify why you have defined the above points? What research does it link to?
-
Do you state which ones are based on stakeholder / primary user needs?
