What is a prototype?

A prototype is a preliminary model or sample of a product developed to test a concept or process or to act as a thing to be replicated or learned from. It is a physical representation of your design, allowing you to interact with it, identify any flaws, and make necessary modifications before proceeding to the final production stage. In other words, prototypes offer a critical risk mitigation mechanism, reducing costly errors and ensuring the product meets quality and functionality requirements. They come in different types – from simple visual mock-ups to complex functional models – depending on the level of detail and functionality needed. Consider prototyping as an investment that validates your design and sets the foundation for a successful product launch.
