The purpose of a prototype in technology product development is to create an early model of the product that can be tested and evaluated. Prototypes allow teams to visualize concepts and assess functionality before full-scale production. This iterative process helps identify potential issues, refine design, and incorporate user feedback, ensuring that the final product aligns with user expectations and market requirements. Prototyping also aids in communication among stakeholders by providing a tangible representation of ideas, promoting collaboration and clearer understanding of the project goals.
