Explain the difference between a working prototype and a fully developed product.

• A. There is no difference; both refer to the same thing.
• B. A working prototype demonstrates core feasibility; a fully developed product is market-ready with complete features and scalability.
• C. A working prototype is final product; a fully developed product is an early concept.
• D. A prototype includes all features, but the product cannot be scaled.

Answer: (B)

A working prototype is first and foremost a test of feasibility. It demonstrates that the core idea can function and show how users would interact with it, but it’s usually not feature-complete, polished, or ready for wide use. The focus is on learning, validating assumptions, and gathering feedback with minimal cost and time.

A fully developed product, by contrast, is prepared for real customers. It includes complete features, a refined user experience, robust performance, and the ability to scale—meaning it can handle growth, a larger user base, and production demands. It’s been tested for quality, reliability, and compliance, and it’s integrated with the necessary support, distribution, and maintenance processes needed to sustain a market launch.

So, the difference lies in purpose and readiness: prototypes prove the concept and inform iteration, while a fully developed product is the finalized, market-ready offering with all the elements needed for broad use.
