Personas definition
A persona is a fictional but realistic and rich representation of a typical user of a product or service, and it is used to understand the needs, goals, and behaviors of different types of users.
Role-based personas synthesize quantitative data you gathered from user and market research, including demographic and behavioral information. Proto-personas are based on the assumptions and past experiences of stakeholders and team members, and they help describe a product's potential user base.[1]
Personas are a valuable tool for understanding and empathizing with your users and can help guide product and marketing decisions.
