HCD.18:9 - Consequences

A constructed specification makes the next evaluation executable: the evaluator knows what work matters, what a defect would change, what evidence to obtain, and which stronger conclusion remains unavailable. Repairs can target a criterion, example, explanation, return, or assistance arrangement instead of expanding the material indiscriminately.

The cost is up-front task and contrast design. That cost is worthwhile when an intuitive score could drive consequential selection or repair. A compatible existing specification avoids repeating it. New audiences or purposes can require a changed specification; preserving the original result meanings makes that change inspectable.
