It’s the process of creating a detailed and realistic representation of a fictional character, or "persona," that is used in various contexts, such as user experience design, marketing, and storytelling. A persona is typically developed based on research and analysis of real people, and is intended to represent the needs, goals, and behaviors of a specific group or segment of users or customers. The persona is used to help designers, marketers, and other professionals create products, campaigns, and other materials that are tailored to the specific needs and characteristics of the intended audience. The goal of persona development is to create a detailed and accurate portrayal of the target audience, which can help to inform the design and marketing decisions of a company or organisation.
