What is a storyboard used to do in UX design?

A storyboard in UX design serves as a visual tool that captures and illustrates a user's journey while interacting with a product or service. By using a series of images or frames, a storyboard allows designers to convey the emotional and contextual aspects of a user’s experience, detailing each step of their interaction. This visualization helps to identify pain points, user motivations, and the overall flow of the experience, ultimately guiding the design process.

It plays a crucial role in understanding not just what users do, but how they feel throughout their interaction, allowing for a richer exploration of design possibilities. By effectively narrating the user's story, designers can create solutions that are more aligned with user needs and expectations, making the storyboard an invaluable asset in the UX design process.

In contrast, the other choices focus on different aspects unrelated to the core purpose of a storyboard in the context of UX design: listing technical requirements, evaluating financial returns, or developing marketing strategies do not emphasize the user experience in the same way a storyboard does.
