| Manufacturing Order (MO) | Production Document | An authorized internal instruction to produce a specific quantity of a finished or semi-finished item within a defined time window. |
| Work Order (WO) | Production Document | A child execution unit derived from a Manufacturing Order, often assigned to a specific work center, shift, or routing operation. |
| Bill of Materials (BOM) | Engineering Structure | A structured list of all raw materials, components, sub-assemblies, and quantities required to produce one unit of a parent item. |
| Multi-Level / Indented BOM | Engineering Structure | A hierarchical BOM representation that expands sub-assemblies into their own component requirements, showing parent-child relationships across multiple levels. |
| Phantom BOM | Engineering Structure | A transient sub-assembly BOM that exists only for engineering clarity; it is never stocked as WIP and is exploded directly into raw components at production time. |
| Routing | Engineering Structure | The ordered sequence of operations required to manufacture an item, including work centers, setup times, run times, and tooling requirements. |
| Operation | Engineering Structure | A single step within a routing, performed at a specific work center, with defined setup time, run time, and labor/machine requirements. |
| Work Center | Shop-Floor Resource | A production resource where operations are performed; may represent a department, cell, machine group, or single machine. |
| Machine | Shop-Floor Resource | A specific piece of equipment within a work center that executes operations and consumes capacity. |
| Tooling / Fixture | Shop-Floor Resource | Auxiliary equipment required to perform an operation, such as dies, molds, jigs, or cutting tools. |
| Capacity | Shop-Floor Resource | The available production time of a work center or machine within a calendar period, typically measured in hours or units. |
| Overall Equipment Effectiveness (OEE) | Shop-Floor Metric | A composite metric of equipment performance calculated as Availability × Performance × Quality. |
| Setup Time | Time Element | The non-productive time required to prepare a work center or machine before production can begin. |
| Run Time | Time Element | The productive time required to process one unit or batch at an operation. |
| Teardown Time | Time Element | The non-productive time required to clean, reset, or release a work center after production ends. |
| Takt Time | Time Element | The maximum allowable time to produce one unit to meet customer demand rate. |
| Cycle Time | Time Element | The actual time elapsed between the completion of two consecutive units. |
| Staging Area | Inventory Location | A designated production location where raw materials and components are reserved or physically placed before being consumed. |
| Floor Stock | Inventory Location | Unbin-tracked material held at the production line for immediate consumption, often managed through backflushing. |
| Backflushing | Consumption Method | An automated method of deducting component quantities from inventory based on finished output and the approved BOM, without individual issue transactions. |
| Manual Material Consumption | Consumption Method | A method where each component issue is recorded individually, typically against a specific work order and operation. |
| Scrap Factor | Production Metric | A planned percentage or quantity of expected material loss during an operation, applied to gross material requirements. |
| Expected Yield | Production Metric | The planned output quantity from a given input, accounting for scrap factors and conversion efficiencies. |
| Actual Yield | Production Metric | The real output quantity achieved from a production run, used for variance analysis. |
| By-Product | Production Output | A secondary output of a production process that has value but is not the primary purpose of the order. |
| Co-Product | Production Output | A primary output jointly produced with another primary output, where both carry significant production intent and cost allocation. |
| Finished Goods (FG) | Production Output | Completed products ready for sale, transfer, or storage. |
| Work in Progress (WIP) | Production Output | Partially completed items that have entered production but are not yet finished. |
| Scrap | Production Output | Material or output that fails quality standards and cannot be economically reworked. |
| Rework | Production Output | Defective output that can be corrected through an additional production process to meet specifications. |
| Quarantine | Quality Status | A holding status for output pending inspection, testing, or disposition decision. |
| Goods Issue Note (GIN) | Inventory Document | The document authorizing the removal of materials from inventory for production consumption. |
| Goods Received Note (GRN) | Inventory Document | The document recording the receipt of finished goods into inventory from production. |
| Lot / Batch | Traceability Unit | A identifiable quantity of material or product produced under uniform conditions and assigned a common identifier. |
| Serial Number (S/N) | Traceability Unit | A unique identifier assigned to a single unit of product for individual tracking. |
| Labor Ticket | Time Document | A record of operator time spent on a specific operation, including setup, run, and indirect activities. |
| Variance | Cost Metric | The difference between standard/planned values and actual values for material, labor, machine, or overhead. |
| Compensating Order | Correction Document | A subsequent manufacturing order created to correct, adjust, or rework a completed production run without altering the original ledger. |
