When workflows are implemented and executed in Fusion Manage, user needs to select the name of the assignee/reviewer amog the full users list. In a company with more than 100 users, one person might not know the one which will follow in the process, but the workflow will need to be executed anyway. It would be strongly needed to implement the "Role" based wf execution: tasks should be assigned to roles, not to people. That's different from security roles, where we setup the access permissions. Role should be an indipendent field to be defined and a user should be able to participate in many roles. A role might also have a leader. At the same time, in wf definition, an administrator should be able to decide wether a task needs to be performed by "any" user belonging to a certain role or by "all" users belonging to the same role.
