Answer:
field change order (FCO)
Step-by-step explanation:
A field change order (FCO) is an order to modify a part of a installation group that is installed at the customer site or in your own organization. You mainly use field change orders to solve production errors collectively, and to introduce product modifications. You can also subcontract the execution of the FCO. A “Field Change Order” (FCO) for construction may be issued in accordance with terms specified in the subcontract. The Project Manager and the Subcontractor agree on a worst-case, not-to-exceed amount for each proposed change and work can begin.
