User profiling is not enough to understand the needs of a user because because it only tells the facts about your users like his/her ID card

Personas

Persona is description of a user. They are not real but imaginary

examples of reals users that they represent

• Each persona is given a name

• Each persona has an image


Different than user profiling, personas tell the behaviour of users; their likes, dislikes and patterns that they follow

Personas tell us:

• Who the users are

• What are the activities they wish to perform

• Why they might use our system

• How our system fits into the context of their life
