Spend Under Management
The amount of currency that was actually invoiced by suppliers (typically in an MSP/VMS relationship) for work performed during a given time frame. This excludes spending that has been identified, but not yet rolled into the program. Suppliers and program managers sometimes describe this spending by breaking it out by job family (professional and commercial) and by worker classification (contract labor, SOW, outsource service contract).
