In product development, what does a working prototype primarily demonstrate?

• A. Final commercial readiness.
• B. Core feasibility of the concept.
• C. Full scalability and market-ready features.
• D. Complete customer support plan.

Answer: (B)

A working prototype demonstrates whether the idea can actually be built and operate in practice. It shows the essential feasibility of the approach by validating that the main functions can work and the key design choices are viable. This hands-on testing helps reveal technical risks and informs early refinements before moving toward production or market readiness. It isn’t about being ready for commercial launch, scalable for mass production, or having a full customer support plan—those aspects come later once feasibility is confirmed and the product is further developed.
