A "persona" refers to the social face or identity that an individual presents to the world. It is often shaped by various factors, including culture, environment, and personal experiences. In psychology, a persona can represent the different roles a person plays in different contexts, such as being a parent, employee, or friend. In marketing and design, a persona is a fictional character created to represent a target audience. This helps businesses understand their customers' needs, preferences, and behaviors. By developing detailed personas, companies can tailor their products and services to better meet the expectations of their audience, ultimately enhancing customer satisfaction.
