Using a specification
A specification is a checklist of requirements written before making, such as size limits, cost, or safety features. Testing a finished prototype against each point shows exactly where it succeeds and where it falls short.

Gathering user views
Watching someone use a product, or asking direct questions, often reveals problems the designer never noticed, such as a handle that is awkward to grip. User feedback should be specific and honest to be genuinely useful.

Refining the design
Refinement means making targeted changes based on testing and feedback, then testing again. This cycle of test–evaluate–improve is repeated until the product reliably meets the specification.
