What defines a digital prototype?

A digital prototype is defined as an interactive simulation of a product for user testing. This type of prototype allows designers and stakeholders to explore the functionality and user experience of a product before its final development. By engaging users with an interactive model, teams can gather valuable feedback on usability and design elements, making it a crucial part of the iterative design process. The goal of a digital prototype is to validate ideas and concepts, ensuring that the final product aligns with user needs and expectations.

In contrast, the other options don't capture the essence of what a digital prototype aims to achieve. A non-interactive model of a product would not provide the necessary engagement or user insights that an interactive prototype facilitates. A theoretical design without user involvement lacks practical testing and validation through real user interactions, while a final version of the product ready for launch represents a completed product and not a prototype, which is a development phase focused on refinement and testing.
