CSCM key terms

The tendency for small shifts in end-customer demand to grow into larger and larger swings in orders, inventories, and production as you move upstream through the supply chain.

The point in a supply chain where production shifts from forecast-driven (push) to customer-order-driven (pull). Positioning it well balances economies of scale against responsiveness to real demand.

Delaying final product configuration or location of differentiation until customer demand is better known, often by holding generic inventory and completing assembly or packaging close to the point of sale.

A capability that is hard for competitors to copy, adds clear value for customers, and can be applied across several products or markets. Firms typically keep these in-house and outsource the rest.

The full cost of getting a product to its destination: purchase price plus freight, duties, tariffs, insurance, handling, and inventory carrying costs incurred along the way.

A purchasing analysis that adds lifecycle costs to the purchase price, including acquisition, operation, maintenance, downtime, quality failures, and disposal, to compare suppliers on a true economic basis.

The difference between forecasted and actual demand. Common measures include mean absolute deviation and mean absolute percentage error, which quantify bias and variability for planning safety stock.

Systematic, one-directional error where forecasts consistently run above or below actual demand. Bias signals a flawed model or process, while random error is unavoidable noise.

A forecast accuracy measure that averages absolute errors divided by actual demand, expressed as a percentage. It is easy to interpret but undefined when actual demand is zero.

A forecasting method that averages demand over a fixed number of recent periods, smoothing out random fluctuations. Longer windows smooth more but react more slowly to genuine trend changes.

A forecasting technique that weights recent observations more heavily than older ones using a smoothing constant between zero and one. Higher constants track shifts faster but amplify noise.

The information about actual customer consumption that flows upstream to trigger replenishment. Sharing it directly with suppliers reduces distortion and dampens the bullwhip effect.

Combining many small requirements into fewer large orders to gain economies of scale in ordering or transport. It amplifies demand variability seen by upstream suppliers and contributes to the bullwhip effect.

The order size that minimizes the sum of ordering costs and inventory holding costs. It assumes stable demand and fixed costs per order, so it is a starting point rather than a final answer.

Extra inventory held to cover uncertainty in demand or replenishment lead time. It is sized from forecast error and target service level, and higher service targets require disproportionately more stock.

The inventory position that triggers a new replenishment order. It equals expected demand during lead time plus safety stock, so longer or more variable lead times raise the trigger level.

The target probability of meeting demand from stock during a replenishment cycle, or the fraction of demand filled immediately. It directly drives required safety stock.

The percentage of demand or order lines satisfied from available inventory without backorder or substitution. It is a customer-facing measure distinct from cycle service level.

Ranking inventory items by annual usage value so that high-value items receive tight control and frequent review, while low-value items get simpler, looser policies.

Counting a rotating subset of inventory items on a scheduled basis instead of a full annual physical count. Frequent counts on high-value items surface errors and root causes earlier.

Receiving goods at a distribution facility and transferring them directly to outbound vehicles with little or no storage. It cuts handling and inventory but demands tight timing and reliable inbound flow.

A facility that receives finished goods and breaks them into smaller shipments for many customers. Its layout and slotting decisions are optimized for fast, accurate outbound flow.

Assigning products to specific warehouse storage locations based on velocity, size, weight, and affinity. Good slotting shortens picker travel and is a major driver of warehouse productivity.

Standard international trade terms defining which party arranges and pays for transport, insurance, customs, and risk transfer at each stage of a shipment between seller and buyer.

A transport document that serves as a receipt for goods, evidence of the carriage contract, and in some forms a document of title that must be surrendered to claim the cargo.

Combining shipments from multiple shippers or orders into a single larger load to obtain better rates and fuller vehicle utilization, at the cost of longer transit for some cargo.

A freight mode where a carrier combines partial loads from several shippers in one trailer. It suits smaller shipments but involves more handling and longer transit than full truckload.

The elapsed time from placing an order to receiving the goods, including order processing, supplier production, and transport. It is a key input to reorder points and safety stock.

A time-phased plan stating which finished products will be produced in which quantities and periods. It translates aggregate plans into specific buildable items within capacity limits.

A system that explodes the master schedule through the bill of materials to calculate component and raw material requirements, offset by lead times, producing planned orders and exception messages.

A structured list of all components, subassemblies, and quantities needed to build one unit of a finished product, organized by levels that drive material requirements planning calculations.

A medium-term check that compares the master production schedule against key resource capacities such as bottleneck work centers, flagging overloads before detailed scheduling begins.

Determining the production resources, labor, and machine hours needed to meet expected demand over a planning horizon, and deciding how to close gaps through hiring, overtime, or outsourcing.

A recurring cross-functional process where sales, marketing, operations, and finance agree on one demand plan and one supply plan, reconciling them into a single business plan.

A structured set of metrics, such as quality, delivery, cost, and responsiveness, used to rate supplier performance over time and inform sourcing, development, or exit decisions.

Deliberately buying a part from only one supplier to gain volume leverage and closer collaboration. It simplifies management but concentrates risk if that supplier fails.

Splitting volume for the same item between two qualified suppliers to reduce dependency and create competitive tension. It typically costs some scale economy but improves resilience.

An arrangement where the supplier monitors the buyer's inventory levels and decides when and how much to replenish, often using shared demand data to reduce stockouts and excess.

The ability of a supply chain to anticipate disruptions, absorb their impact, and recover quickly to normal or better performance, built through redundancy, flexibility, and visibility.

The extent to which a firm can see real-time status, inventory, and events across its upstream and downstream partners, enabling faster detection and response to disruptions.

Managing supply chain activities to limit environmental harm and uphold social responsibility, covering emissions, waste, resource use, labor practices, and ethical sourcing across partners.
