Storytelling can be used in different stages of design, from research to prototyping to testing. For example, during research you can use storytelling to collect user insights through interviews, surveys, or observations. Additionally, you can use storytelling to analyze and synthesize the data by creating personas, user journeys, or empathy maps. When prototyping, storytelling can be used to communicate ideas and concepts through sketching, wireframing, or mockups. It can also be used to validate and refine prototypes by creating user stories, scenarios, or storyboards. Lastly, in testing storytelling can be used to evaluate solutions and measure their impact through usability tests, user feedback sessions, or case studies. It can also be used to showcase results and recommendations with videos, presentations, or reports.
