What is the specification is the yardstick?Show answer
A design specification is the detailed list of requirements a solution must satisfy. It is written after research, at the end of the investigation stage, and it drives everything that follows: ideas are generated to meet it, development is judged against it, and the final product is evaluated against it. A weak specification leads to an aimless project; a strong one keeps the design on target.
What is make points measurable?Show answer
Wherever a category allows, write a measurable point with a figure, unit or clear condition. "Must be light" cannot be tested; "must weigh under 1.5 kg" can. Measurable points make idea selection and final evaluation objective. Some points (aesthetics, for instance) are harder to measure, but even there you can be specific: "must use calm colours suited to a bedroom" is better than "must look nice".
