What are writing good specification points?Show answer
Strong specification points are specific and, where possible, measurable, so they can be tested. "Be attractive" is weak; "appeal to 8 to 12 year olds, using bright colours and a friendly cartoon style" is usable. Each point should trace back to the brief or research, so the specification is justified rather than invented. A specification typically covers function, audience, appearance, materials, size, cost, safety and any brand requirements.
What is success criteria?Show answer
Success criteria are the specific, testable standards by which the finished design will be judged, drawn directly from the specification. For example, "a first-time user can complete the task in under one minute" or "the text is legible from three metres". Clear success criteria make later evaluation objective and honest, because the design is measured against agreed targets rather than personal taste.
What is types of constraint?Show answer
Constraints are the limits within which a designer works. Common ones include:
