PROTOTYPING A prototype is an early, rapidly constructed working version of the proposed information system. User input and approval is essential at every stage of the systems development process. Prototyping allows users to examine a model that accurately represents system outputs, inputs, interfaces, and processes. Users can test-drive the model and either approved it or request changes. In some situations, the prototype evolves into the final version of the information system; in other cases, the prototype is intended only to validate user requirements and is discarded afterward. Prototyping offers the following benefits: Users and systems developers can avoid misunderstandings. System developers can create accurate specifications for the finished system based on the prototype. Managers can evaluate a working model more effectively than a paper specification. Systems analysts can use a prototype to develop testing and training procedures before the finished system is available.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
