Supply Chain Operations Reference Model. This is the model developed by the Supply-Chain Council (SCC) , and is build around six major processes: plan, source, make, deliver, return, and enable. The aim of the SCOR is to provide a standardized method of measuring supply chain performance, and to use a common set of metrics to benchmark against other organizations.


A performance measurement tool used to capture a summary of the key performance indicators (KPIs) /metrics of a company. Metrics dashboards/scorecards should be easy to read and usually have red, yellow, green indicators to flag when the company is not meeting its metrics targets. Ideally, a dashboard/scorecard should be cross functional in nature and include both financial and non-financial measures. In addition, scorecards should be reviewed regularly - at least on a monthly basis and weekly in key functions, such as manufacturing and distribution where activities are critical to the success of a company. The dashboard/scorecards philosophy can also be applied to external supply chain partners like suppliers to ensure that their objectives and practices align. Synonym: Dashboard

The ability to move the product out of the warehouse door. This is a critical capacity and one that only brick-and-mortar firms bring to the B2B table. Dot coms have the technology, but that's only part of the equation. The need for SCE is what is driving the dot coms to offer equity partnerships to the wholesale distributors.

Supply Chain Integration (SCI)

Likely to become a key competitive advantage of selected e-marketplaces. Similar concept to the back-end integration, but with greater emphasis on the moving of goods and services.

Supply Chain Inventory Visibility

Software applications that permit monitoring events across a supply chain. These systems track and trace inventory globally on a line-item level, and notify the user of significant deviations from the plans. Companies are provided with realistic estimates of when the material will arrive.

Supply Chain Management (SCM) - as defined by the Council of Supply Chain Management Professionals (CSCMP)

Supply chain management encompasses the planning and management of all activities involved in sourcing and procurement, conversion, and all logistics management activites. Importantly, it also includes coordination and collaboration with channel partners, which can be suppliers, intermediaries, third party service providers, and customers. In essence, supply chain management integrates supply and demand management within and across companies. Supply chain management is an integrating function with primary responsibility for linking major business functions and business processes within and across companies into a cohesive, high-performing business model. It includes all of the logistics managment activities noted above, as well as manufacturing operations, and it drives coordination of processes and activities with and across marketing, sales, product design, finance, and information technology.

Supply Chain Network Design Systems

The systems employed in optimizing the relationships among the various elements of the supply chain manufacturing plants, distribution centers, points of sale, as well as raw materials, relationships among product families, and other factors to synchronize supply chains at a strategic level.

Supply Chain Operations Reference Model

This is the model developed by the Supply-Chain Council SCC and is built around six major processes: plan, source, make, deliver, return and enable. The aim of the SCOR is to provide a standardized method of measuring supply chain performance and to use a common set of metrics to benchmark against other organizations.

Supply Chain Resiliency

A term describing the level of hardening of the supply chain against disasters.

Supply Chain Strategic Planning

The process of analyzing, evaluating, and defining supply chain strategies, including network design, manufacturing and transportation strategy, and inventory policy.

Supply Chain Vulnerability

Of equal importance to Variability, Velocity and Volume in the elements of the Supply Chain. The term evaluates the supply chain based on the level of acceptance of the five steps of disaster logistics being planning, detection, mitigation, response and recovery.

Supply Chain-Related Finance and Planning Cost Elements

One of the elements comprising a company’s total supply-chain management costs. These costs consist of the following: (1) Supply-Chain Finance Costs: Costs associated with paying invoices, auditing physical counts, performing inventory accounting, and collecting accounts receivable. Does NOT include customer invoicing/ accounting costs (see Order Management Costs). (2) Demand/Supply Planning Costs: Costs associated with forecasting, developing finished goods, intermediate, subassembly or end item inventory plans, and coordinating Demand/Supply

Supply Chain-Related IT Costs

Information technology (IT) costs (in US dollars) associated with major supply chain management processes as described below. These costs should include: * Development costs (costs incurred in process reengineering, planning, software development, installation, implementation, and training associated with new and/or upgraded architecture, infrastructure, and systems to support the described supply chain management processes) , *Execution costs (operating costs to support supply chain process users, including computer and network operations, EDI and telecommunications services, and amortization/depreciation of hardware) * Maintenance costs (costs incurred in problem resolution, troubleshooting, repair, and routine maintenance associated with installed hardware and software for described supply chain management processes. Includes costs associated with database administration systems configuration control, release planning, and management) .These costs are associated with the following processes:PLAN1. Product Data Management -

Supply Chian Planning

The determination of a set of policies and procedures that govern the operation of a supply chain. Planning includes the determination of marketing channels, promotions, respective quantities and timing, inventory and replenishment policies, and production policies. Planning establishes the parameters within which the supply chain will operate.

Supply Planning

The process of identifying, prioritizing, and aggregating, as a whole with constituent parts, all sources of supply that are required and add value in the supply chain of a product or service at the appropriate level, horizon, and interval.

Supply Requisition

A form used by a cost center to request the issue of a commodity or commodities carried in storeroom stock.

Supply Warehouse

A warehouse that stores raw materials. Goods from different suppliers are picked, sorted, staged, or sequenced at the warehouse to assemble plant orders.

Support Costs

Costs of activities not directly associated with producing or delivering products or services. Examples are the costs of information systems, process engineering, and purchasing. Also see: Indirect Cost.

Supportive Project Management

Managing specific activities for relocating existing customer environments into the new locations, including management of all vendors in the de-installation and re-installation of their equipment, managing/providing the transportation for the overall effort, managing the documentation (site assessment, transportation schedules, implementation plan, and so on), and providing on-site supervision for each relocation phase. See Project Management.


EDIFACT Supplier response message


An add-on charge to the applicable charges, motor carriers have a fuel surcharge, and railroads can apply a surcharge to any joint rate that does not yield 110% of variable cost.


Commodities that are not returnable to the vendor for credit, but are useful for some purpose and are excess or obsolete for the cost center owning the goods.

Surrogate [item] Driver

In ABC costing, a substitute for the ideal cost driver, but closely correlated to the ideal driver, where [item] is Resource, Activity, or Cost Object. A surrogate driver is used to significantly reduce the cost of measurement while not significantly reducing accuracy. For example, the number of production runs is not descriptive of the material-disbursing activity, but the number of production runs may be used as an activity driver if material disbursements correlate well with the number of production runs.


No longer qualified as a prospective bidder and may be removed from the list of vendors to receive bids.

Sustaining Activity

An activity that benefits an organizational unit as a whole, but not any specific cost object.

Swing Gear

Items or equipment used during a transition period to limit downtime and increase availability during a relocation or migration event.

Switch engine

A railroad engine that is used to move rail cars short distances within a terminal and plant.

Switching company

A railroad that moves rail cars short distances, switching companies connect two mainline railroads to facilitate through movement of shipments.


See SWOT Analysis.

SWOT Analysis

An analysis of the strengths, weaknesses, opportunities, and threats of and to an organization. SWOT analysis is useful in developing strategy.


The concept that all supply chain functions are integrated and interact in real time; when changes are made to one area, the effect is automatically reflected throughout the supply chain.
