An extensive glossary of supply chain terms. If we missed one feel free to tell us in the comments and we’ll add it to the list!
A
ABC Analysis. A form of Pareto analysis applied to a group of products in order to apply selective inventory management controls. The inventory value for each item is obtained by multiplying the annual demand by unit cost and the entire inventory is then ranked in descending order of cost. However, the classification parameter can be varied; for example, it is possible to use the velocity of turnover rather than annual demand value.
ABC Classification. The classification of inventory, after ABC analysis, into three basic groups for the purpose of stock control and planning. Although further divisions may be established, the 3 basic categories are designated A, B and C as follows:
A Items. An item that, according to an ABC classification, belongs to a small group of products that represents around 75-80% of the annual demand, usage or production volume, in monetary terms, but only some 15-20% of the inventory items. For the purpose of stock control and planning, the greatest attention is paid to this category of A-products. A items may also be of strategic importance to the business concerned. B items – An intermediate group, representing around 5-10% of the annual demand, usage or production value but some 20-25% of the total, that is paid less management attention. C Items – A product which according to an ABC classification belongs to the 60-65% of inventory that represents only around 10-15% the annual demand, usage or production value. Least attention is paid to this category for the purpose of stock control and planning and procurement decisions for such items may be automated.
Active Inventory. Any item or element of inventory which has been used or sold within a given period. Often set at 12 months.
Advanced Shipping Notice (ASN). Detailed shipment information transmitted by the shipper to a customer or consignee in advance of delivery, designating the contents (individual products and quantities of each) and nature of the shipment. In EDI data standards this is referred to as an 856 transaction. May also include carrier and shipment specifics including time of shipment and expected time of arrival. The ASN data can be valuable in providing digital knowledge about what is in a shipment in a way that it can be used to eliminate manual data entry of each shipment.
Aggregate Inventory Management. The size of many inventories requires that they be broken down into groupings for the purpose of control. Aggregated inventory is the further collection of these groupings into a single entity to enable the establishment of operating policies, key performance indicators, targets and reports. Aggregate Inventory Management enables such things as the overall level of inventory desired to be established and then appropriate controls implemented to ensure that individual operating decisions achieve that goal, at optimum cost.
Allocated Stock. A part or product that has been reserved, but not yet withdrawn or issued from stock, and is thus not available for other purposes.
All-Time Order. The last order for a particular product in the last phase of its life cycle. This order is of such a size that the stock provided will satisfy all expected future demand (see all time requirement below) for the product concerned. Sometimes known as a life of type order.
All-Time Requirement. The total requirement for a particular product to be expected in the future. Normally used for products in the last phase of their life cycles, when production is (nearly) stopped.
All-Time Stock. The stock resulting from the assessment of an all-time requirement and delivery of an all-time order. If necessary, controls can be set for such stock to avoid consumption of items for reasons over and above those for which usage was predicted.
Anticipation Stock. Inventory held in order to be able to satisfy a demand with seasonal fluctuations with a production level that does not fluctuate at all or that varies to a lesser extent than the demand.
Availability. The primary measure of system performance relating to the expected percentage of the supported system that will be available at a random point in time and not out of service for lack of spares.
Available Stock. The stock available to service immediate demand.
Available to Promise (ATP). The uncommitted portion of a company’s inventory and planned production, maintained in the master schedule to support customer order promising. The ATP quantity is the uncommitted inventory balance in the first period and is normally calculated for each period in which an MPS receipt is scheduled. In the first period, ATP includes on-hand inventory less customer orders that are due and overdue.
B
Backflushing. The deduction from inventory, after manufacture, of the component parts used in a parent by exploding the bill of materials by the production total of parents produced.
Backhaul. Generally, a back haul is any return load taken after the delivery has been made. An example of this would be the collection of supplier loads from the supplier by the retailer for delivery into the retailer’s own RDC.
Backorder. A customer demand for which no stock is available and where the customer is prepared to wait for the item to arrive in stock.
Benchmarking. The process of comparing performance against the practices of other leading companies for the purpose of improving performance. Companies also benchmark internally by tracking and comparing current performance with past performance. Benchmarking seeks to improve any given business process by exploiting “best practices” rather than merely measuring the best performance. Best practices are the cause of best performance. Studying best practices provides the greatest opportunity for gaining a strategic, operational, and financial advantage.
Beyond Economic Repair (BER). Where the projected cost of repair, normally for a repairable or rotable item, exceeds a management set percentage of the replacement value of the item concerned.
Batch Number. A code used to identify the specific production point, for a product or an assembly, in a manufacturing or assembly process.
Bill of Material. A listing of components, parts, and other items needed to manufacture a product, showing the quantity of each required to produce each end item. A bill of material is similar to a parts list except that it usually shows how the product is fabricated and assembled. Also called a product structure record, formula, recipe, or ingredients list.
C
Category. A distinct, separate, and manageable group of products that are perceived by consumers to be interrelated.
Category Management. The management of groups of products that are interchangeable, or substitutable, in meeting consumer needs as opposed to the traditional concentration on individual products and brands.
Central Distribution Center. A warehouse that is the sole stocking point for the distribution system that it serves. Grocery manufacturers commonly have central (or national) distribution centers, stocked by various manufacturing points and serving various retailer distribution warehouses. See National distribution centers.
Co-Managed Inventory. A support arrangement similar to Vendor Managed Inventory but where replacement orders for the vendor-owned stock are agreed by the user prior to delivery.
Component. A part, ingredient, or subassembly that is both a component to a higher-level part, and a parent part to other components.
Component Part. Raw material, ingredient, part, or subassembly that goes into a higher-level assembly, compound, or other part.
Composite Delivery. A multi-temperature distribution center. The receipt, storage and handling of products would typically take place in a variety of on-site chambers each operating at a specific temperature.
Composite Distribution Centre (CDC). A multi-temperature distribution centre. The receipt, storage and handling of products would typically take place in a variety of on-site chambers each operating at a specific temperature.
Consignment Stock. The stock of goods held by an external customer which is still the property of the supplier but for which payment is only made when stock is sold or used by the customer.
Consolidation. The loading of two or more suppliers’ deliveries to a retailer’s RDC on a single vehicle. This aims to improve load utilization and improve unloading time at the RDC.
Consolidation Centers. Depots that store and/or process stock (see cross docking) into full loads for delivery to retailer RDCs.
Consumable. A classification of stock used to describe items or products that are totally consumed in use e.g., paper, oil, grease etc.
Cost to Serve. Is a Supply Chain analytical approach, utilizing activity-based cost techniques that identifies the costs of servicing specific customers, with specific products, by allocating costs to customers, products and channels.
Cross Docking. A system where products for store orders are not put away into the warehouse racking for later picking but are processed into store orders on arrival at the RDC. This can entail breaking down the inward delivery into store ready consignments or if the consignments are pallet sized moving the pallets across the docking area for loading onto the store delivery vehicle. This movement of product across warehouse vehicle docking bays gives the process its name
D
De-Coupling Stock. Inventory accumulated between dependent activities in the goods flow to reduce the need for completely synchronized operations.
Deduct Point. The point in the production process up to which all the parts assumed to have been used (as defined in the bill of material) are “backflushed”, (automatically deducted) from the inventory records. Also see Backflushing.
Demand Driven Supply Chains. This is where a supply system is in direct response to a single point of demand. All the components across a supply chain are synchronized to meet the demand that it is trying to fulfill.
Dependent Demand. A classification used in inventory control where the demand for one item has a direct mathematical relationship with the demand for another higher level or parent component and where the demand for that item is ultimately dependent on the demand for the higher level or parent item.
Deterministic Inventory Control Models. An inventory control system where all the variables and parameters used are known or can be calculated with certainty. The rate of demand for items, and the associated inventory costs, are assumed to be known with assurance and the replenishment lead time is assumed to be constant and independent of demand.
Direct Store Delivery (DSD). Delivery by suppliers directly to their customers retail outlet, rather than via the retailers DC.
Distribution Requirement Planning DRPI. The function of determining the need to replenish inventory at branch warehouses over a forward time period. A time-phased order point approach is used where planned orders at branch warehouse level are exploded via MRP logic to become gross requirements on the supplying source enabling the translation of inventory plans into material flows. In the case of multi-level distribution networks, this explosion process can continue down through the various levels of regional warehouses, master warehouse, factory warehouse etc. and become input to the master production schedule.

Integrated Business Planning. Planning process that integrates across two or more functions in a business or government entity referred to as an enterprise to maximize financial value. The specific functional areas in a company as well as the industry domain associated with the company defines the specific type of IBP process. The key requirement for IBP is that two or more functional process areas must be involved and maximizing (optimizing) of financial value should be done.
Independent Demand. A classification used in inventory control systems where the demand for any one item has no relationship with the demand for any other item and variations in demand occur because of random influences from the marketplace.

Issues Based Supply Chain Development. This is an approach that is used to first assess the problems, issues and root causes in a supply chain and then uses the root causes to understand the strategic gaps in the supply chain.
Issue Tickets. An authorization to withdraw allocated stock items from the stockroom. When presented to the stockroom, they can be exchanged for the parts designated.
Issuing Documents. The physical documents that communicate specifically how much of what needs to be issued to where. Issue lists, issue tickets, and issue decks are all forms of issuing documents.
J

M
Material Requirements Planning (MRP I). A system to support manufacturing and fabrication organizations by the timely release of production and purchase orders using the production plan for finished goods to determine the materials required to make the product. Orders for dependent demand items are phased over time to ensure that the flow of raw materials and in-process inventories matches the production schedules for finished products. The 3 key inputs are the master production schedule, inventory status records and product structure records.
Manufacturing Resource Planning (MRP II). A method for the effective planning of all the resources of a manufacturing company. Ideally it addresses operational planning in units, financial planning in money, and has a simulation capability to answer what if questions. It is made up of a variety of functions, each linked together: business planning, master (or production) planning, master production scheduling, material requirements planning, capacity requirements planning and the execution systems for capacity and priority. Outputs from these systems would be integrated with financial reports such as the business plan, purchase commitment report, shipping budget, stock projections in money etc. Manufacturing resource planning is a direct out-growth and extension of material requirements planning (MRP-1).
