Work-order control is the management of production work orders from release through execution, tracking, and closure. In manufacturing, it refers to the rules, system functions, and shop-floor practices used to ensure that authorized work is performed against the correct part, quantity, routing, materials, instructions, and status.
Work-order control is commonly handled in MES, ERP, or integrated production execution systems. It may include releasing orders to the floor, assigning operations, controlling sequence, recording labor and machine activity, enforcing quality holds, capturing completion quantities, and closing or updating order status. In regulated or quality-sensitive environments, it also supports traceability by linking execution records to lots, serial numbers, operators, equipment, revisions, and inspection results.
The term should not be confused with the work order itself. A work order is the record or instruction to perform work; work-order control is the management of that record through the production process. It also differs from maintenance work-order management, although similar control concepts are used in enterprise asset management and maintenance systems.
