Microcomputer prototyping is a systems analysis methodology that enables engineers to place limited scope, working models of manufacturing and information control systems into production without the extensive expertise and involvement of data processing professionals. With a prototype, a design engineer can work directly with the user to develop functions, input screens, and report output that satisfies the user. Changes can be incorporated rapidly and quickly evaluated. This is made possible by the flexible use of microcomputers and the many tools available for development. When a prototype is complete, the resulting system demonstrates much of the function required by a fully implemented system, providing a foundation for the final system specification.
