What does "proof of concept" mean in programming?
proof of concept is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A small implementation built to demonstrate that a technical approach is feasible, without full production quality. A proof of concept (PoC) answers the question 'can we build this?' before committing to building it properly.
Example
"We built a proof of concept integrating the new LLM API in one day — now we know it is feasible and can estimate the real work."
