A prototype project can generally be described as a preliminary pilot, test, evaluation, demonstration, or agile development activity used to evaluate the technical or manufacturing feasibility or military utility of a particular technology, process, concept, end item, effect, or other discrete feature. Prototype projects may include systems, subsystems, components, materials, methodology, technology, or processes.  By way of illustration, a prototype project may involve: a proof of concept, a pilot, a novel application of commercial technologies for defense purposes; a creation, design, development, validation, demonstration of technical or operational utility; or combinations of the foregoing, related to a prototype.
