When should a product management team utilize a prototype?

This choice implies that the prototype is being used merely as a demonstration of features rather than as a tool for gathering user input. While showcasing features is important, the primary purpose of a prototype is to engage users and assess their responses to the concept and usability, which goes beyond mere presentation.

Creating training materials for IT technicians involves finalized or near-final products to provide accurate instructions and support. Prototypes are not suitable for this purpose since they often lack complete functionality and may not represent the final application’s features and workflows, thus misleading the training process.

While testing user interface designs can be a part of the prototyping process, this choice is too narrow. It suggests that the prototype is solely for UI design testing instead of encompassing broader user feedback. Prototyping serves multiple purposes, including usability testing across various aspects of the product, not just the interface.
