A user persona is a fictional character created to represent a specific type of user of a product or service. Personas are used in user-centred design and research to provide a consistent, realistic representation of how potential users might interact with a system. Personas are based on market research and can be used to help shape the development of a product or service by providing insights into the needs, goals, and behaviour of users. User personas can also be used to create user stories, which are short descriptions of how a persona would use a product or service to achieve their goals. User personas are typically created by conducting interviews and surveys with potential users, and then synthesizing the data into summaries that capture the essential characteristics of each persona. Personas are often given names and assigned photos or illustrations to help designers and others connect with them on a personal level. While personas are fictional characters, they should be based on real data about users and should be used as tools to help design better products and services.
