Storyboards are tools that help communicating how a user would experience a product or service and how the proposed design will help them accomplish their goals (user journeys). This methodology has been borrowed by the movie industry and allows describing the interaction between the user and a product/service on one or more frame by showing the key experience touchpoints.
Storyboards are great ways to share a concept with customers and make them understand concepts and design ideas. They can be used during design workshops to gather feedback and to help identify areas of improvement or missing elements of the experience. They can be considered as quick prototypes of the experience which also help entrepreneurs empathise with their customers.
