My current client has projects that need to be able to plan work based on job roles that are in a specific region, specific business line and specific job role. (A project that needs to be executed in Hungary, for a XX product line with a XX Resource)... The projects needs to be able to identify the roles on a task for planning. If we had job role pools, we could create a pool of job roles specific to a region and business line and those roles would be available for the PM to assign to tasks in the business case development and task assignments during planning. Otherwise, we have to create a complex acroynm scheme to identify the specific job role so that when we are doing a more strategic planning of resources, the allocations are appropriately reflected, without a lot of overhead to maintain the list of job roles.
