Before starting out with prototype model in software engineering first, let us see w hat is prototyping in software software prototyping, refers to the activity of creating prototypes of software applications. The prototype creation model is a method of developing the software in which a prototype of software or app is constructed, tested, and then reworked as needed until an acceptable result is.

Prototype model should be used when the desired system needs to have a lot of interaction with the end users. It also creates a base to produce the final system. The prototype model requires that before carrying out the development of actual software, a working prototype of the system should be built. Software prototyping is used in typical cases and the decision should be taken very carefully so that the efforts spent in building the prototype add considerable value to the final software developed.
