A role is an abstract definition of a set of responsibilities that encompass tasks to be performed and work products to be produced. Roles are typically realized by an individual, or a set of individuals, working together as a team. An individual may fulfill many different roles. Roles are not individuals, nor are they necessarily equivalent to job titles; instead, they describe how individuals assigned to the roles will behave. To see the roles for each process, select one of the processes on this page. Because ITUP does not fully address all of the PRM-IT processes, only the roles associated with the 20 processes in ITUP are represented here.
