Prototyping is an essential step in the product design and development process. It involves creating a preliminary version of a product to test and validate its functionality, user experience, and design concepts. Prototypes can range from low-fidelity paper sketches to high-fidelity interactive mock-ups. By building prototypes, designers and product teams can gather valuable feedback early in the process, identify and address potential issues, and refine the product before investing significant time and resources into full-scale development. Prototyping allows for iterative improvements, facilitates effective communication between stakeholders, and ultimately leads to the creation of a more user-centered and successful product.
