A demonstration or prototype that shows the feasibility of an idea or theory, typically created to verify that a concept can work in practice.
This phrase emerged in the mid-20th century from engineering and scientific contexts, where researchers needed to prove their theoretical concepts could function in reality. It became widely adopted in business and technology sectors by the 1980s as a way to minimize risk before full development.
The abbreviation 'POC' has become so common in tech circles that it's spawned the verb 'to POC something,' meaning to create a quick demonstration. Interestingly, many successful products started as simple proofs of concept that far exceeded their original scope.
