I would say that user stories are created tounderstand how much time it takes
to develop the stories or the tasks. They arecreated by clients or the
development team and contain a short description ofwhat the system or the
product should do. The list of user stories collectedwill be used for
development planning purposes like what stories/features inter-dependentand
what stories should be developed first, what would be the ideal developmenttime
and whether it is a low/medium or high priority feature.
On the other hand while personas are also used for documenting the
end-userneeds, they are used as a motivating tool for the designer and to
communicatethe end-user needs to clients and the development team who are
involved in theproject and help them understand the emotions and goals of the
users. Personasare created by user researchers or designers and it details the
goals of theusers, their work environment and the tasks that they do to achieve
the goal.
So, personas are appropriate to use at the end of the research phase
tocommunicate end user goals and user stories should be used during
developmentplanning to understand how many iterations it would take and what
storiesshould be developed in each iteration.
