The term “Proof of Concept” (PoC) refers to an early prototype or feasibility study in project management and product development that demonstrates the feasibility and potential of an idea or technology. A PoC is created in the initial phases of a project to validate fundamental concepts and assess whether a planned solution meets the required expectations and needs. It serves to validate concepts, minimize risks, and convince stakeholders. A PoC shows whether an idea is technically and practically viable, helping to identify potential issues early. A successful PoC can persuade investors and partners of the feasibility and value of a project and prevents unnecessary investments in unfeasible projects. The results of a PoC are used for further project planning and are a valuable tool for driving innovation and efficiently utilizing resources.
