Which of the following techniques is used to test customer acceptance of the solution and to measure marketplace demand?

Interviews gather in-depth qualitative information from specific individuals but lack the scale needed to measure overall marketplace demand or customer acceptance statistically.

A market survey collects structured data directly from potential customers to assess how well a solution meets their needs and whether they would adopt it. It measures marketplace demand by reaching a broad audience, providing both quantitative metrics and qualitative feedback. This makes it the primary tool for validating a solution concept before full investment.

Technology assessment evaluates the technical feasibility, maturity, and suitability of a technology choice, not whether customers will accept the solution or whether market demand exists.

Prototyping creates a preliminary working model to test functionality and gather usability feedback, but it is not designed to measure broad marketplace demand or customer acceptance across the market.
