When requirements are known, a preliminary design or quick design for the system is created. Prototype methodology is defined as a software development model in which a prototype is built, test, and then reworked when needed until an acceptable prototype is achieved. The prototype gives us the feel of a maximum complete software. A software for which the original source code is made freely. A prototyping model begins with requirements analysis and the requirements of the system are defined in detail. These kinds of activities can also sometimes be called a beta phase or beta testing, where an initial project gets evaluated by a smaller class of users before full development.
For example, a prototype in the electronics industry is going to be vastly different than a prototype for a mechanical engineering application. In the systems development life cycle sdlc prototyping model, a basic version of the system is built, tested, and then reworked as necessary.
