Persona

Personas are fictitious representatives for real people. Alan Cooper's company, Cooper cooper, uses personas to abstractly represent users for which their software is being designed. The personas contain detailed information about their social and professional life. Small teams of interaction designers analyse these personas and re-enact different scenarios in order to discover their goals. Future software is developed with the user's needs in mind.

Even if it seems logical to fulfill many users' needs, it makes sense to design for one persona, because it is representing one group of users that will use the software later on. (Although the software should fulfill many users needs, it should be designed for one persona, since this persona represents the largest group of users that will be using the software)

The users that are represented by the chosen persona are the most likely to buy the product since the software satisfies their needs.
