for unstructured, decision-oriented applications for which requirements cannot be immediately visualized. Prototyping consists of building an experimental system rapidly and inexpensively for end users to interact with and evaluate. The prototype is refined and enhanced until users are satisfied that it includes all of their requirements and can be used as a template to create the final system. Prototyping encourages end-user involvement in systems development and iteration of design until specifications
