In terms of an information system, prototypes are employed to help system designers build an information system that intuitive and easy to manipulate for end users. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping. Prototyping is a technique that could be used in conjunction with agile software development to put a partially completed product in front of a customer for feedback before committing to the complete development of the final product.

This model works best in scenarios where not all of the project requirements are known in detail ahead of time.
There are many stages in the software development life cycle sdlc including planning, design, development, testing, and maintenance. Software prototypes may give test users a false impression of how good the finished article may be. This allows software development firms to show their customers how their webbased application or app will look and behave. The prototyping model is a systems development method in which a prototype is built, tested and then reworked as necessary until an acceptable outcome is achieved from which the complete system or product can be developed. Prototyping is the process of building a model of a system.
