A workload is the time assigned to a person or team to satisfy a requirement. Values must be greater than or equal to zero, and limited to one decimal place (for example: 3.5).
No time unit is enforced to measure workloads but, in order to allow PowerDesigner to properly calculate totals, you should decide on and consistently use the same unit (hour or day) for all workloads.
You assign workloads to requirements on their Detail tab, where there are fields to record workloads assigned to four individual people or groups.
You can only assign workloads to requirements that have no sub-requirements. Workloads for parent requirements, packages, and the model are read-only fields calculated as the sums of all their sub-requirement workloads.
