Pre-production Build

A design verification process whereby a prototype(s) is built to evaluate the design, accuracy of the documentation, and potential manufacturing issues. This stage usually comes after the design stage and before full-scale production and is used to verify many design aspects, such as material acquisition, assembly methods, software loading, and basic functionality. Various tests may be performed on the pre-production build, including fit and function tests, reliability tests, thermal tests, and electromagnetic compatibility tests.
