The degree to which a prototype is exactly like the final product.

The degree to which a prototype is exactly like the final product.

• A. CAD
• B. Fidelity
• C. Data Modelling
• D. Digital human

Answer: (B)

How closely a prototype matches the final product is measured by fidelity. Fidelity describes how realistic and complete a prototype is in representing the final design, including its look, features, and behavior. In practice, prototypes vary from low fidelity—quick, rough representations—to high fidelity, which are almost indistinguishable from the final product and suitable for detailed testing. The other terms don’t capture this idea: CAD is software for creating digital models, Data Modelling is about organizing information structures, and Digital human relates to simulating human factors, not the prototype’s closeness to the final product.
