“Do Personas have to be accurate? Do they require a large body of research? No, I conclude. The Personas must indeed reflect the target group for the design team, but that is about all. A Persona allows designers to bring their own life-long experience to bear on the problem, and because each Persona is a realistic individual person, the designers can focus upon features, behaviors, and expectations appropriate for this individual, allowing the designer to screen off from consideration all those other wonderful ideas they may have.” (Donald Norman) – courtesy of elearningpost
