The ability of a supply chain to absorb disruption, adapt its operations, and sustain or recover required performance.

Supply chain risk management

The identification, assessment, and mitigation of threats that could disrupt supply, operations, or the flow of goods and services.

Supply chain transparency

The disclosure and availability of meaningful information about supply chain participants, practices, and conditions beyond the immediate transaction.

Supply chain visibility

Access to relevant information about suppliers, inventory, orders, and movements across the supply network.

Sustainable procurement

Purchasing that considers environmental, social, governance, and economic impacts across the lifecycle of goods or services.

Synergy

Incremental value made possible by combining businesses, including cost, revenue, or capital improvements beyond their separate operations.

Tail spend

The fragmented, relatively low-value purchases that sit outside major managed categories and often involve many suppliers or transactions.

Takt time

The production pace required to meet customer demand, calculated as available production time divided by required customer volume.

Tariff

A customs tax or schedule of duty rates applied to traded goods, commonly imports.

Tariff Classification

Tariff classification is the process of determining where a product belongs within the applicable customs tariff nomenclature. It applies the schedule’s legal descriptions, interpretation rules, and notes to the product’s characteristics and condition.

Taxonomy

A structured classification hierarchy used to organize items, suppliers, or spending into consistent categories.

Third-party logistics (3PL)

The use of an external provider to perform logistics activities such as transportation, warehousing, fulfillment, or freight forwarding.

Three-way match

The comparison of a purchase order, receiving record, and supplier invoice to identify discrepancies before payment approval.

Throughput

The rate at which a system produces or moves output over a defined period.

Total cost of ownership (TCO)

The full cost of acquiring, using, maintaining, and ultimately disposing of a product or asset over its life, rather than its purchase price alone.

Total landed cost

The cost of a product delivered to a specified destination, including its purchase price and applicable transportation, handling, duties, taxes, and other acquisition charges.

Traceability

The ability to follow an object's origin, processing history, location, and movement through relevant stages of its lifecycle.

The data used to fit a machine-learning model and establish the patterns or relationships it uses.

Transit time

The elapsed time between a shipment's pickup and its delivery.

Transition service agreement (TSA)

Transportation management system (TMS)

Software used to plan, execute, monitor, and manage freight movements and associated transportation activities.

UNSPSC

Unstructured data

Information such as free text, documents, or images that is not organized in a predefined tabular data model.

Value chain

The linked activities through which a business or industry creates and delivers value, from inputs through production and service to customers.

Value Creation Plan

A value creation plan is a prioritized set of initiatives designed to improve a business’s operating and financial performance, with defined ownership, resources, timing, and measures. It translates a strategic or investment thesis into specific changes that management can execute and evaluate.

Value stream mapping

A visual representation of material and information flows used to understand the current process and design an improved future state.

Vendor-managed inventory (VMI)

An arrangement in which the supplier manages replenishment using agreed customer demand and inventory information, with ownership governed separately.

Vertical Integration

Vertical integration brings activities at different stages of a value chain under common ownership or control. A company may expand upstream into supply or production inputs, downstream into distribution or customer access, or across several stages.

Warehouse management system (WMS)

Software that directs and records warehouse activities such as receiving, put-away, picking, shipping, and inventory control.

Work in process (WIP)

Materials, components, and subassemblies that have entered production but have not yet become completed finished goods.

Working capital

Current assets minus current liabilities, a measure that includes more than cash and reflects both operating assets and short-term obligations.

X-bar and R Charts

X-bar and R charts are paired statistical process-control charts used with repeated subgroups of measured data. The X-bar chart monitors subgroup averages, while the R chart monitors the within-subgroup range, or the difference between the largest and smallest values.

XYZ Analysis

XYZ analysis groups inventory items according to demand variability or predictability. X items generally have relatively stable demand, Y items have more variable or patterned demand, and Z items have highly variable or irregular demand.

Yard Management System (YMS)

A yard management system, or YMS, is software used to track and coordinate trailers, containers, vehicles, and their movements within a facility’s yard. It supports the handoffs among gate activity, yard locations, dock assignments, and inbound or outbound processing.

Yield (Manufacturing)

Manufacturing yield is the proportion of input that becomes acceptable output within a defined process and measurement basis. It may be expressed using units, mass, volume, or another appropriate basis, and the definition must state how rework, scrap, and incomplete production are treated.

Zero-Based Budgeting (ZBB)

Zero-based budgeting, or ZBB, builds a budget by justifying required activities and spending rather than treating the prior budget as an automatic entitlement. The analysis starts with current needs, service levels, and cost drivers, then determines the resources required to support them.

Zone Picking

Zone picking divides a warehouse’s picking activity into defined areas, with workers or equipment picking items within their assigned zones. Orders are completed by moving through zones sequentially or by combining items picked separately in different zones.
