open-in-new
<p>A proof of concept (POC or PoC), also known as proof of principle, is an inchoate realization of a certain idea or method in order to demonstrate its <a href="/facts/Feasibility_study/5YtobnNC">feasibility</a> or viability. A proof of concept is usually small and may or may not be complete, but aims to demonstrate in principle that the concept has practical potential without needing to fully develop it. </p><p>A proof of value (PoV) is sometimes used along proof of concept, and differs by focusing more on demonstrating the potential customer <a href="/facts/Use_case/8pNHjsIr">use case</a> and value, and is usually less in-depth than a proof of concept. </p>
