    • What is prototyping?
      • The prototype model addresses the common problem of customers not knowing all the requirements at the beginning of the project. They often know a high level of requirements but cannot specify them in detail required to make a successful system.
        • A prototype is a working model of a new system.
        • It involves a working model being created, tested, and used to give the user a "look and feel" experience.
        • The WM is shown to the end user(s) who tests it and provides feedback and then it is refined again and again until they are satisfied.
    • What are the two types of prototyping?
      • Evolutionary prototyping: involves building a working model or rough-cut of a new system to evaluate its potential
      • Throw-away prototyping: The prototype is used to give the user a chance to experience the "look and feel" of the system.
      • This is continually refined so that it eventually evolves into an acceptable user system.
        • Evolutionary prototyping: involves building a working model or rough-cut of a new system to evaluate its potential
      • Before it is discarded once the system specification has been established.
        • Throw-away prototyping: The prototype is used to give the user a chance to experience the "look and feel" of the system.
