Building software application prototypes that display the capabilities of the product under development, but may not have the exact logic of the original software, is referred to as software prototyping. It's built, tested, and revised until it's deemed suitable as a prototype. It also serves as a foundation for the final system or program. It's best used in situations where the project's requirements aren't fully understood. Software prototyping is gaining popularity as a software development strategy because it allows for an early understanding of customer requirements.
