Which artifact is used to validate that an idea is technically feasible before full development?

• A. Paper prototypes
• B. MMF
• C. Proof of concept
• D. MVP

Answer: (C)

When you want to know if an idea can actually be built with the available technology, you test feasibility early with a focused, small-scale artifact. A proof of concept is exactly that: a minimal build or demonstration that shows the core technical idea can work in practice. It isolates the critical challenge and proves the approach is viable before committing to full development, so teams can decide whether to proceed, adjust the plan, or pivot.

Other options serve different purposes. Paper prototypes are used to explore and test user interface ideas and workflows, not to prove technical viability. Minimum Marketable Feature focuses on the smallest piece of functionality that can be released to market, which is about scope and delivery, not feasibility. A minimum viable product is a usable version of the product meant to learn from real users, not to confirm technical feasibility before full build.
