A persona is a fictitious person, usually based on real information about people of the same type, who designers and other creatives develop and deploy as a way of communicating important information about potential users of a proposed new commodity. Personas are often coupled with scenarios, where the fictitious person is put into a fictitious setting that involves using the possible commodity. We have argued elsewhere (Scaletsky, Basapur, and Ruecker 2014) that there is a family resemblance among designs, prototypes, and scenarios, since each of them is a way of thinking through making about possible preferred futures.
