Question
What does every specification criterion need?
Answer
A finding behind it, a statement of what the solution must DO, a number or condition, a test, and a band — essential or desirable.
Question
Essential vs desirable criteria?
Answer
Essential: the solution fails without it, so it filters ideas out. Desirable: a real improvement taken if it costs nothing else, used to break ties between ideas that all pass.
Question
Why must a criterion state behaviour, not a material?
Answer
"Made from aluminium" writes a solution into the specification and rules out better ones. The criterion is the behaviour aluminium was wanted for.
Question
Where is a specification used after it is written?
Answer
To compare ideas against each other, to decide when development is finished, and to structure the final evaluation — which is why a vague one costs marks three stages later.
