Which term relates to the degree to which a prototype matches the final product?

• A. CAD
• B. Bottom-up modelling
• C. Fidelity
• D. Data Modelling

Answer: (C)

Fidelity describes how closely a prototype mirrors the final product in appearance and behavior. A high-fidelity prototype recreates near-final dimensions, materials, finishes, and functioning features, so you can test real user interactions and manufacturing considerations. A low-fidelity prototype is rough and quick to make, used mainly to explore concepts and basic usability rather than exact look or performance. The term you’re looking for specifically captures the degree of match between the prototype and what will be produced, whereas CAD refers to digital design software, bottom-up modelling is an assembly approach, and data modelling deals with organizing information.
