In this Engage Talk, the panel discusses the role of prototyping in entrepreneurship and innovation. Drawing on perspectives from research, design, and startup development, the speakers explore how prototypes can be used to test ideas, solve problems, and learn from users throughout the development process. The discussion follows the example of Anue, a startup developing a new container for donated breast milk and illustrates how simple prototypes helped refine the product and identify user needs. The panel also explains how prototyping supports collaboration, communication, and decision-making, while reducing the risk of investing time and resources in the wrong solution. The video offers a practical introduction to prototyping and highlights its value in developing products, services, and new ways of working.
