Guide Clarifies PoC vs. Prototype vs. MVP
A new breakdown clarifies the often-confused terms for early-stage product development. It defines a Proof-of-Concept (PoC) as testing technical feasibility, a Prototype as a non-functional UX mockup for user testing, and an MVP as the simplest functional version that delivers real user value.
The cost of confusing these terms is not just semantic; it's a primary reason startups fail. Teams that build a beautiful prototype for an idea that isn't technically feasible, or launch an MVP for a product nobody wants, burn through capital and lose market opportunities. Misaligned expectations between founders, engineers, and investors often stem from calling a non-functional mockup an "MVP." A Proof-of-Concept (PoC) is a low-cost, internal experiment designed to answer one question: "Can this be built?" It focuses exclusively on technical feasibility, often has no user interface, and its code is frequently discarded. The goal of a PoC is to de-risk novel technology or complex integrations before any significant resources are invested in design or development. Prototypes, in contrast, tackle usability risk by answering "How will this feel to a user?" Built with tools like Figma, these interactive but often non-functional models test user flows and design assumptions. While prototypes are crucial for gathering design feedback, a common mistake is interpreting positive user reactions as validation of market demand. The Minimum Viable Product (MVP) is the first version of the product that is actually shipped to real users to test business viability. An MVP is a functional product, not a simulation, designed to solve a core problem and gather feedback on market demand. Dropbox famously started with an MVP that was just an explainer video, which validated significant market interest before they built the full product. For aspiring Product Managers, demonstrating a clear understanding of these stages is critical in internship interviews. Case studies often require candidates to define the core features of an MVP or explain how they would use data from an MVP launch to iterate. Building a side project correctly might mean starting with a PoC to test a new API, then a prototype to refine the UX, before ever writing production code for an MVP.
