Constraints are added to policies and determine the criteria that need to be met for an assignment group to be assigned a task. For a list of the constraints, see Optimization features used with Schedule Optimization.

Constraints are mandatory and tasks won't be assigned if the assignment group doesn't fit the constraint. They define the 'must-haves' for agents to even be considered for a task. Constraints are mandatory conditions embedded in policies. If an assignment group fails to meet a constraint, they're out of the running for that task. For example, if "Enable Mandatory Skills" is activated, only assignment groups with agents possessing the required skills will be considered for task assignments.
