The purpose of Product Integration is to construct the product from the device components, ensure that the product, when assembled, performs appropriately, i.e. retains the necessary features and consistency characteristics, and deliver the product. Product Integration is more than just a one-time installation of the product components at the end of the design and manufacturing cycle. Incremental product integration can be achieved using an iterative method of installing, testing,& and adding further component parts. It can be conducted using highly automated builds and continuous integration of the completed unit tested product.
