Distribution Channel

The distribution route, from raw materials through consumption, along which products travel. See: channels of distribution, marketing channel.

Gantt Chart

The earliest and best-known type of planning and control chart, especially designed to show graphically the relationship between planned performance and actual performance over time. Named after its originator, Henry L. Gantt, the chart is used for (1) machine loading, in which one horizontal line is used to represent capacity and another to represent load against that capacity; or (2) monitoring job progress, in which one horizontal line represents the production schedule and another parallel line represents the actual progress of the job against the schedule in time. Synonym: job progress chart, milestone chart.

Load load profile

The established start and finish dates for all work orders and determining load in relevant period at each work center, a work center load profile can be established. A load profile is a graphic comparison of each work center's available capacity and the load established by the planned and released orders for each time period of the plan.

Quality standards

The expectations of customers expressed in terms of the minimum acceptable production or service standards

Rated Capacity

The expected output capability of a resource or system. Capacity is traditionally calculated from such data as planned hours, efficiency, and utilization. The rated capacity is equal to hours available × efficiency × utilization. Synonym: calculated capacity, effective capacity, nominal capacity, standing capacity.

Receiving

The function encompassing the physical receipt of material, the inspection of the shipment for conformance with the purchase order (quantity and damage), the identification and delivery to destination, and the preparation of receiving reports.

Priority Planning

The function of determining what material is needed and when. Master production scheduling and material requirements planning are the elements used for the planning and replanning process to maintain proper due dates on required materials. Synonym: dispatch list.

CRP - Capacity Requirements Planning

The function of establishing, measuring, and adjusting limits or levels of capacity. The term capacity requirements planning in this context refers to the process of determining in detail the amount of labor and machine resources required to accomplish the tasks of production. Open shop orders and planned orders in the MRP system are input to CRP, which through the use of parts routings and time standards translates these orders into hours of work by work center by time period. Even though rough-cut capacity planning may indicate that sufficient capacity exists to execute the MPS, CRP may show that capacity is insufficient during specific time periods. See: capacity planning.

Capacity Management

The function of establishing, measuring, monitoring, and adjusting limits or levels of capacity in order to execute all manufacturing schedules.

Transportation

The function of planning, scheduling, and controlling activities related to mode, vendor, and movement of inventories into and out of an organization.

Merger

The joining of two businesses to create a new organisation

MPS - Master Production Schedule

The master production schedule is a line on the master schedule grid that reflects the anticipated build schedule for those items assigned to the master scheduler. The master scheduler maintains this schedule, and in turn, it becomes a set of planning numbers that drives material requirements planning. It represents what the company plans to produce expressed in specific configurations, quantities, and dates. The master production schedule is not a sales item forecast that represents a statement of demand. The master production schedule must take into account the forecast, the production plan, and other important considerations such as backlog, availability of material, availability of capacity, and management policies and goals. See: master schedule.

Master Schedule

The master schedule is a format that includes time periods (dates), the forecast, customer orders, projected available balance, available-to-promise, and the master production schedule. The master schedule takes into account the forecast; the production plan; and other important considerations such as backlog, availability of material, availability of capacity, and management policies and goals. See: master production schedule.

Available for use

The material or component that has been completed and is ready for use by the nest operation

Capacity

The maximum possible output that can be produced with the given resources

Physical Supply

The movement and storage of goods from suppliers to manufacturing. The cost of physical supply is ultimately passed on to the customer.

Cash Flow

The net flow of dollars into or out of the proposed project. The algebraic sum, in any time period, of all cash receipts, expenses, and investments. Also called cash proceeds or cash generated.

Inventory Turnover

The number of times that an inventory cycles, or "turns over," during the year. A frequently used method to compute inventory turnover is to divide the average inventory level into the annual cost of sales. For example, an average inventory of $3 million divided into an annual cost of sales of $21 million means that inventory turned over seven times. Synonym: inventory turns, turnover. See: inventory velocity.

Available Inventory

The on-hand inventory balance minus allocations, reservations, backorders, and (usually) quantities held for quality problems.

Flowchart

The output of a flowcharting process, a chart that shows the operations, transportation, storages, delays, inspections, and so on related to a process. Flowcharts are drawn to better understand processes. The flowchart is one of the seven tools of quality. Synonym: flow diagram. See: block diagram, flow process chart.

Quality Costs

The overall costs associated with prevention activities and the improvement of quality throughout the firm before, during, and after production of a product. These costs fall into four recognized categories: internal failure costs, external failure costs, appraisal costs, and prevention costs. Internal failure costs relate to problems before the product reaches the customer. These usually include rework, scrap, downgrades, reinspection, retest, and process losses. External failure costs relate to problems found after the product reaches the customer. These usually include such costs as warranty and returns. Appraisal costs are associated with the formal evaluation and audit of quality in the firm. Typical costs include inspection, quality audits, testing, calibration, and checking time. Prevention costs are those caused by improvement activities that focus on reducing failure and appraisal costs. Typical costs include education, quality training, and supplier certification.

See: business plan, operational plan, strategic planning, strategy, tactical plan.

Employee Empowerment

The practice of giving non-managerial employees the responsibility and the power to make decisions regarding their jobs or tasks. It is associated with the practice of transfer of managerial responsibility to the employee. Empowerment allows the employee to take on responsibility for tasks normally associated with staff specialists. Examples include allowing the employee to make scheduling, quality, process design, or purchasing decisions.

Bachhauling

The process of a transportation vehicle returning from the original destination point to the point of origin. The 1980 Motor Carrier Act deregulated interstate commercial trucking and thereby allowed carriers to contract for the return trip. The backhaul can be with a full, partial, or empty load. An empty backhaul is called deadheading.

Order Entry

The process of accepting and translating what a customer wants into terms used by the manufacturer or distributor. The commitment should be based on the available-to-promise (ATP) line in the master schedule. This can be as simple as creating shipping documents for finished goods in a make-to-stock environment, or it might be a more complicated series of activities, including design efforts for make-to-order products. See: master schedule, order service.

Requirements Explosion

The process of calculating the demand for the components of a parent item by multiplying the parent item requirements by the component usage quantity specified in the bill of material. Synonym: explosion.

Demand Planning

The process of combining statistical forecasting techniques and judgment to construct demand estimates for products or services (both high and low volume; lumpy and continuous) across the supply chain from the suppliers' raw materials to the consumer's needs. Items can be aggregated by product family, geographical location, product life cycle, and so forth, to determine an estimate of consumer demand for finished products, service parts, and services. Numerous forecasting models are tested and combined with judgment from marketing, sales, distributors, warehousing, service parts, and other functions. Actual sales are compared with forecasts provided by various models and judgments to determine the best integration of techniques and judgment to minimize forecast error. See: demand management.

CTP - Capable to Promise

The process of committing orders against available capacity as well as inventory. This process may involve multiple manufacturing or distribution sites. Capable-to-promise is used to determine when a new or unscheduled customer order can be delivered. Capable-to-promise employs a finite-scheduling model of the manufacturing system to determine when an item can be delivered. It includes any constraints that might restrict the production, such as availability of resources, lead times for raw materials or purchased parts, and requirements for lower-level components or subassemblies. The resulting delivery date takes into consideration production capacity, the current manufacturing environment, and future order commitments. The objective is to reduce the time spent by production planners in expediting orders and adjusting plans because of inaccurate delivery-date promises.

Priority Control

The process of communicating start and completion dates to manufacturing departments in order to execute a plan. The dispatch list is the tool normally used to provide these dates and priorities based on the current plan and status of all open orders.

RCCP - Rough-Cut Capacity Planning

The process of converting the master production schedule into requirements for key resources, often including labor; machinery; warehouse space; suppliers' capabilities; and, in some cases, money. Comparison to available or demonstrated capacity is usually done for each key resource. This comparison assists the master scheduler in establishing a feasible master production schedule. Three approaches to performing RCCP are the bill of labor (resources, capacity) approach, the capacity planning using overall factors approach, and the resource profile approach. See: bill of resources, capacity planning, capacity planning using overall factors, product load profile, resource profile.

Capacity Planning

The process of determining the amount of capacity required to produce in the future. This process may be performed at an aggregate or product-line level (resource requirements planning), at the master-scheduling level (rough-cut capacity planning), and at the material requirements planning level (capacity requirements planning). See: capacity requirements planning, resource planning, rough-cut capacity planning.

Sales Planning

The process of determining the overall sales plan to best support customer needs and operations capabilities while meeting general business objectives of profitability, productivity, competitive customer lead times, and so on, as expressed in the overall business plan. See: production planning, sales and operations planning.

Mixed-Model Scheduling

The process of developing one or more schedules to enable mixed-model production. The goal is to achieve a day's production each day. See: mixed-model production.

What-If Analysis

The process of evaluating alternate strategies by answering the consequences of changes to forecasts, manufacturing plans, inventory levels, and so forth. See: simulation.

Outsourcing

The process of having suppliers provide goods and services that were previously provided internally. Outsourcing involves substitution—the replacement of internal capacity and production by that of the supplier. See: subcontracting.

Order Promising

The process of making a delivery commitment (i.e., answering the question "When can you ship?"). For make-to-order products, this usually involves a check of uncommitted material and availability of capacity, often as represented by the master schedule available-to-promise. Synonym: customer order promising, order dating. See: available-to-promise, order service.

Quality Control

The process of measuring quality conformance by comparing the actual with a standard for the characteristic and acting on the difference. See: quality assurance/control.

Throughput

The rate at which the system generates "goal units." Because throughput is a rate, it is always expressed for a given time period—such as, per month, week, day, or even minute. If the goal units are money, throughput will be an amount of money per time period. In that case, throughput is calculated as revenues received minus totally variable costs divided for the chosen time period.

Tracking Signal

The ratio of the cumulative algebraic sum of the deviations between the forecasts and the actual values to the mean absolute deviation. Used to signal when the validity of the forecasting model might be in doubt. See: forecast error, mean absolute deviation.

Component

The raw material, part, or subassembly that goes into a higher level assembly, compound, or other item. This term may also include packaging materials for finished items. See: ingredient, intermediate part.

Economies of scale

The reduction in average cost per unit (purchasing, technical, management specialisation)

POS - Point of Sale

The relief of inventory and computation of sales data at the time and place of sale, generally through the use of bar coding or magnetic media and equipment.

Repetitive Manufacturing

The repeated production of the same discrete products or families of products. Repetitive methodology minimizes setups, inventory, and manufacturing lead times by using production lines, assembly lines, or cells. Work orders are no longer necessary; production scheduling and control are based on production rates. Products may be standard or assembled from modules. Repetitive is not a function of speed or volume. Synonym: repetitive process, repetitive production. See: project manufacturing.

Protective Capacity

The resource capacity needed to protect system throughput—ensuring that some capacity above the capacity required to exploit the constraint is available to catch up when disruptions inevitably occur. Nonconstraint resources need protective capacity to rebuild the bank in front of the constraint or capacity-constrained resource (CCR) and/or on the shipping dock before throughput is lost and to empty the space buffer when it fills.

Green Reverse Logistics

The responsibility of the supplier to dispose of packaging materials or environmentally sensitive materials such as heavy metals.

Materials Management What is the role of Materials Management?

The role of Material Management is to balance the company's resources with demand. Balancing department conflicts. Two Major Areas in Material Management: 1. Manufacturing Planning & Control System (MPC) - MRPII , ERP 2. Physical Supply & Distribution - manage purchasing and control of production materials, controlling WIP, controlling storage, distribution of finished goods.

Manufacturing Process

The series of operations performed upon material to convert it from the raw material or a semifinished state to a state of further completion. Manufacturing processes can be arranged in a process layout, product layout, cellular layout, or fixed-position layout. Manufacturing processes can be planned to support make-to-stock, make-to-order, assemble-to-order, and so forth, based on the strategic use and placement of inventories. See: production process, transformation process.

Priority planning

The setting and maintaining of time phased due dates is called priority planning

Ordering Cost

Used in calculating order quantities, the costs that increase as the number of orders placed increases. It includes costs related to the clerical work of preparing, releasing, monitoring, and receiving orders, the physical handling of goods, inspections, and setup costs, as applicable. See: acquisition cost, inventory costs.

Under utilisation

Using less than the 100% capacity of the firm. Low utilisation causes fixed costs to be spread over fewer units and so the firm may need to increase capacity utilisation through increasing demand and thus output or rationalising

Subcontracting

Using the resources of another organisation, or letting out the business's resources in order to increase efficiency

Utilization

Utilization - is based on the number of hours of work input (hours actually worked) at a work center in a period compared to available time in that period, expressed as rate or a percentage. In other words the utilization rate adjusts the available time. What is the Utilization if a work center is available for 160 hours a week about the hours actually worked only amount to 120 hours? Utilization = 120 X 100% = 75% =160

Flow Shop

A form of manufacturing organization in which machines and operators handle a standard, usually uninterrupted, material flow. The operators generally perform the same operations for each production run. A flow shop is often referred to as a mass production shop or is said to have a continuous manufacturing layout. The plant layout (arrangement of machines, benches, assembly lines, etc.) is designed to facilitate a product "flow." Some process industries (chemicals, oil, paint, etc.) are extreme examples of flow shops. Each product, though variable in material specifications, uses the same flow pattern through the shop. Production is set at a given rate, and the products are generally manufactured in bulk. Synonym: flow line, flow manufacturing, flow plant.

Summarized Bill of Material

A form of multilevel bill of material that lists all the parts and their quantities required in a given product structure. Unlike the indented bill of material, it does not list the levels of manufacture and lists a component only once for the total quantity used.

Indented Bill of Material

A form of multilevel bill of material. It exhibits the highest-level parents closest to the left margin, and all the components going into these parents are shown indented toward the right. All subsequent levels of components are indented farther to the right. If a component is used in more than one parent within a given product structure, it will appear more than once, under every subassembly in which it is used.

PDCA - Plan-Do-Check-Act

A four-step process for quality improvement. In the first step (plan), a plan to effect improvement is developed. In the second step (do), the plan is carried out, preferably on a small scale. In the third step (check), the effects of the plan are observed. In the last step (action), the results are studied to determine what was learned and what can be predicted. The plan-do-check-¬action cycle is sometimes referred to as the Shewhart cycle (because Walter A. Shewhart discussed the concept in his book Statistical Method from the Viewpoint of Quality Control) and as the Deming circle (because W. Edwards Deming introduced the concept in Japan; the Japanese subsequently called it the Deming circle). Synonym: plan-do-check-act cycle, Shewhart circle of quality, Shewhart cycle. See: Deming circle.

UN Global Compact Management Model

Many accounting systems also include the value of semifinished stock and components in this category. Synonym: in-process inventory.

Histogram

A graph of contiguous vertical bars representing a frequency distribution in which the groups or classes of items are marked on the x axis and the number of items in each class is indicated on the y axis. The pictorial nature of the histogram lets people see patterns that are difficult to see in a simple table of numbers. The histogram is one of the seven tools of quality.

Control Chart

A graphic comparison of process performance data with predetermined computed control limits. The process performance data usually consist of groups of measurements selected in regular sequence of production that preserve the order. The primary use of control charts is to detect assignable causes of variation in the process as opposed to random variations. The control chart is one of the seven tools of quality. Synonym: process control chart.

Process Flow Diagram

A graphical and progressive representation of the various steps, events, and tasks that make up an operations process. This diagram provides the viewer with a picture of what actually occurs when a product is manufactured or a service is performed.

Scatter Chart

A graphical technique to analyze the relationship between two variables. Two sets of data are plotted on a graph, with the y axis used for the variable to be predicted and the x axis used for the variable to make the prediction. The graph will show possible relationships (although two variables might appear to be related, they might not be—those who know most about the variables must make that evaluation). The scatter chart is one of the seven tools of quality. Synonym: cross plot, scatter diagram, scatterplot.

Master Planning

A group of business processes that includes the following activities: demand management (which includes forecasting and order servicing); production and resource planning; and master scheduling (which includes the master schedule and the rough-cut capacity plan).

Product Family

Private Carrier

A group that provides transportation exclusively within an organization. Antonym: common carrier.

TOC - Theory of Constraints

A holistic management philosophy developed by Dr. Eliyahu M. Goldratt that is based on the principle that complex systems exhibit inherent simplicity. Even a very complex system comprising thousands of people and pieces of equipment can have, at any given time, only a very, very small number of variables—perhaps only one, known as a constraint—that actually limit the ability to generate more of the system's goal.

Two-Card Kanban System

A kanban system where a move card and production card are employed. The move card authorizes the movement of a specific number of parts from a source to a point of use. The move card is attached to the standard container of parts during movement to the point of use of the parts. The production card authorizes the production of a given number of parts for use or replenishment. Synonym: dual-card kanban system. See: one-card kanban system.

One-Card Kanban System

A kanban system where only a move card is employed. Typically, the work centers are adjacent, therefore no production card is required. In many cases, squares located between work centers are used as the kanban system. An empty square signals the supplying work center to produce a standard container of the item. Synonym: single-card kanban system. See: two-card kanban system.

Value Stream Mapping

A lean production tool to visually understand the flow of materials from supplier to customer that includes the current process and flow as well as the value-added and non-value-added time of all the process steps. Used to lead to reduction of waste, decrease flow time, and make the process flow more efficient and effective.

Distribution Center

A location used to store inventory. Decisions driving warehouse management include site selection, number of facilities in the system, layout, and methods of receiving, storing, and retrieving goods.

Fixed Order Quantity

A lot-sizing technique in MRP or inventory management that will always cause planned or actual orders to be generated for a predetermined fixed quantity, or multiples thereof, if net requirements for the period exceed the fixed order quantity.

Lot-for-Lot

A lot-sizing technique that generates planned orders in quantities equal to the net requirements in each period. See: discrete order quantity.

Period Order Quantity

A lot-sizing technique under which the lot size is equal to the net requirements for a given number of periods (e.g., weeks into the future). The number of periods to order is variable, each order size equalizing the holding costs and the ordering costs for the interval. See: discrete order quantity, dynamic lot sizing.

Split Lot

A manufacturing order quantity that has been divided into two or more smaller quantities, usually after the order has been released. The quantities of a split lot may be worked on in parallel, or a portion of the original quantity may be sent ahead to a subsequent operation to be worked on while work on the remainder of the quantity is being completed at the current operation. The purpose of splitting a lot is to reduce the lead time of the order.

Cellular Manufacturing

A manufacturing process that produces families of parts within a single line or cell of machines controlled by operators who work only within the line or cell.

Overlapped Schedule

A manufacturing schedule that "overlaps" successive operations. Overlapping occurs when the completed portion of an order at one work center is processed at one or more succeeding work centers before the pieces left behind are finished at the preceding work centers. Synonym: lap phasing, operation overlapping, telescoping. See: send ahead. Antonym: gapped schedule, overlapped production.

CRM - Customer Relationship Management

A marketing philosophy based on putting the customer first. The collection and analysis of information designed for sales and marketing decision support (as contrasted to enterprise resources planning information) to understand and support existing and potential customer needs. It includes account management, catalog and order entry, payment processing, credits and adjustments, and other functions. Synonym: customer relations management.

VMI - Vendor-Managed Inventory

A means of optimizing supply chain performance in which the supplier has access to the customer's inventory data and is responsible for maintaining the inventory level required by the customer. This activity is accomplished by a process in which resupply is done by the vendor through regularly scheduled reviews of the on-site inventory. The on-site inventory is counted, damaged or outdated goods are removed, and the inventory is restocked to predefined levels. The vendor obtains a receipt for the restocked inventory and accordingly invoices the customer. See: continuous replenishment.

On-Time Schedule Performance

A measure (percentage) of meeting the customer's originally negotiated delivery request date. Performance can be expressed as a percentage based on the number of orders, line items, or dollar value shipped on time.

Level of Service

A measure (usually expressed as a percentage) of satisfying demand through inventory or by the current production schedule in time to satisfy the customers' requested delivery dates and quantities. In a make-to-stock environment, level of service is sometimes calculated as the percentage of orders picked complete from stock upon receipt of the customer order, the percentage of line items picked complete, or the percentage of total dollar demand picked complete. In make-to-order and design-to-order environments, level of service is the percentage of times the customer-requested or acknowledged date was met by shipping complete product quantities. Synonym: measure of service, service level. See: cycle service level.

Record Accuracy

A measure of the conformity of recorded values in a bookkeeping system to the actual values; for example, the on-hand balance of an item maintained in a computer record relative to the actual on-hand balance of the items in the stockroom.

Stockout Percentage

A measure of the effectiveness with which a company responds to actual demand or requirements. The stockout percentage can be a measurement of total orders containing a stockout to total orders, or of line items incurring stockouts to total line items ordered during a period. One formula is: stockout percentage = (1 - customer service ratio) × 100 percent. Antonym: customer service ratio.

Efficiency

A measure, as a percentage, of the actual output compared with the standard expected output

MRP II - Manufacturing Resource Planning

A method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning in dollars, and has a simulation capability to answer what-if questions. It is made up of a variety of processes, each linked together: business planning, production planning (sales and operations planning), master production scheduling, material requirements planning, capacity requirements planning, and the execution support systems for capacity and material. Output from these systems is integrated with financial reports such as the business plan, purchase commitment report, shipping budget, and inventory projections in dollars. Manufacturing resource planning is a direct outgrowth and extension of closed-loop MRP.

Periodic Replenishment

A method of aggregating requirements to place deliveries of varying quantities at evenly spaced time intervals, rather than variably spaced deliveries of equal quantities.

Backflush

A method of inventory bookkeeping where the book (computer) inventory of components is automatically reduced by the computer after completion of activity on the component's upper-level parent item based on what should have been used as specified on the bill of material and allocation records. This approach has the disadvantage of a built-in differential between the book record and what is physically in stock. Synonym: explode-to-deduct, post-deduct inventory transaction processing. See: pre-deduct inventory transaction processing

Kanban

A method of just-in-time production that uses standard containers or lot sizes with a single card attached to each. It is a pull system in which work centers signal with a card that they wish to withdraw parts from feeding operations or suppliers. The Japanese word kanban, loosely translated, means card, billboard, or sign but other signaling devices such as colored golf balls have also been used. The term is often used synonymously for the specific scheduling system developed and used by the Toyota Corporation in Japan. See: move card, production card, synchronized production.

Batch Picking

A method of picking orders in which order requirements are aggregated by product across orders to reduce movement to and from product locations. The aggregated quantities of each product are then transported to a common area where the individual orders are constructed. See: discrete order picking, order picking, zone picking.

Discrete Order Picking

A method of picking orders in which the items on one order are picked before the next order is picked. See: batch picking, order picking, zone picking.

Wave Picking

A method of selecting and sequencing picking lists to minimize the waiting time of the delivered material. Shipping orders may be picked in waves combined by common carrier or destination, and manufacturing orders in waves related to work centers.

Fixed-location Storage

A method of storage in which a relatively permanent location is assigned for the storage of each item in a storeroom or warehouse. Although more space is needed to store parts than in a random-location storage system, fixed locations become familiar, and therefore a locator file may not be needed. See: random-location storage.

Zone Picking

A method of subdividing a picking list by areas within a storeroom for more efficient and rapid order picking. A zone-picked order must be grouped to a single location before delivery or must be delivered to different locations, such as work centers. See: batch picking, discrete order picking, order picking.

QFD - Quality Function Deployment

A methodology designed to ensure that all the major requirements of the customer are identified and subsequently met or exceeded through the resulting product design process and the design and operation of the supporting production management system. QFD can be viewed as a set of communication and translation tools. QFD tries to eliminate the gap between what the customer wants in a new product and what the product is capable of delivering. QFD often leads to a clear identification of the major requirements of the customers. These expectations are referred to as the voice of the customer (VOC). See: house of quality.

Six Sigma

A methodology that furnishes tools for the improvement of business processes. The intent is to decrease process variation and improve product quality.

Mission Statement

A mission statement is the tool used to formally announce the company's intention, its scope of operations, and its purpose.

CPM - Critical Path Method

A network planning technique for the analysis of a project's completion time used for planning and controlling the activities in a project. By showing each of these activities and their associated times, the critical path, which identifies those elements that actually constrain the total time for the project, can be determined. See: critical chain method, network analysis, critical activity, critical path.

CPI - Continuous Process Improvement

A never-ending effort to expose and eliminate root causes of problems: small-step improvement as opposed to big-step improvement. Synonym: continuous improvement. See: kaizen.

Time Bucket

A number of days of data summarized into a columnar or row-wise display. A weekly time bucket would contain all of the relevant data for an entire week. Weekly time buckets are considered to be the largest possible (at least in the near and medium term) to permit effective MRP.

Downtime

A period when machinery is not being used, either as a result of maintenance or when parts of the machinery have to be adapted to produce a slightly different unit of production

Customs Broker

A person who manages the paperwork required for international shipping and tracks and moves the shipments through the proper channels.

Lean Production

A philosophy of production that emphasizes the minimization of the amount of all the resources (including time) used in the various activities of the enterprise. It involves identifying and eliminating non-value-adding activities in design, production, supply chain management, and dealing with customers. Lean producers employ teams of multiskilled workers at all levels of the organization and use highly flexible, increasingly automated machines to produce volumes of products in potentially enormous variety. It contains a set of principles and practices to reduce cost through the relentless removal of waste and through the simplification of all manufacturing and support processes. Synonym: lean, lean manufacturing.

FPO - Firm Planned Order

A planned order that can be frozen in quantity and time. The computer is not allowed to change it automatically; this is the responsibility of the planner in charge of the item that is being planned. This technique can aid planners working with MRP systems to respond to material and capacity problems by firming up selected planned orders. In addition, firm planned orders are the normal method of stating the master production schedule. See: planning time fence.

Time Fence

A policy or guideline established to note where various restrictions or changes in operating procedures take place. For example, changes to the master production schedule can be accomplished easily beyond the cumulative lead time, while changes inside the cumulative lead time become increasingly more difficult to a point where changes should be resisted. Time fences can be used to define these points. See: demand time fence, hedge, planning time fence.

Quantity Discount

A price reduction allowance determined by the quantity or value of a purchase.

Continuous Replenishment

A process by which a supplier is notified daily of actual sales or warehouse shipments and commits to replenishing these sales (by size, color, and so on) without stockouts and without receiving replenishment orders. The result is a lowering of associated costs and an improvement in inventory turnover. See: rapid replenishment, vendor-managed inventory.

Production Planning

A process to develop tactical plans based on setting the overall level of manufacturing output (production plan) and other activities to best satisfy the current planned levels of sales (sales plan or forecasts), while meeting general business objectives of profitability, productivity, competitive customer lead times, and so on, as expressed in the overall business plan. The sales and production capabilities are compared, and a business strategy that includes a sales plan, a production plan, budgets, pro forma financial statements, and supporting plans for materials and workforce requirements, and so on, is developed. One of its primary purposes is to establish production rates that will achieve management's objective of satisfying customer demand by maintaining, raising, or lowering inventories or backlogs, while usually attempting to keep the workforce relatively stable. Because this plan affects many company functions, it is normally prepared with information from marketing and coordinated with the functions of manufacturing, sales, engineering, finance, materials, and so on. See: aggregate planning, production plan, sales and operations planning, sales plan.

Production planning

A process to develop tactical plans based on setting the overall level of manufacturing output and other activities to best satsify the current planned levels of sales while meeting the general business objectives of profitability ,productivity and so on as expressed in the business plan.

S&OP - Sales and Operations Planning

A process to develop tactical plans that provide management the ability to strategically direct its businesses to achieve competitive advantage on a continuous basis by integrating customer-focused marketing plans for new and existing products with the management of the supply chain. The process brings together all the plans for the business (sales, marketing, development, manufacturing, sourcing, and financial) into one integrated set of plans. It is performed at least once a month and is reviewed by management at an aggregate (product family) level. The process must reconcile all supply, demand, and new-product plans at both the detail and aggregate levels and tie to the business plan. It is the definitive statement of the company's plans for the near to intermediate term, covering a horizon sufficient to plan for resources and to support the annual business planning process. Executed properly, the sales and operation planning process links the strategic plans for the business with its execution and reviews performance measurements for continuous improvement. See: aggregate planning, executive sales and operations planning, production plan, production planning, sales plan, tactical planning.

Quality at the Source

A producer's responsibility to provide 100 percent acceptable quality material to the consumer of the material. The objective is to reduce or eliminate shipping or receiving quality inspections and line stoppages as a result of supplier defects.

Postponement

A product design strategy that shifts product differentiation closer to the consumer by postponing identity changes, such as assembly or packaging, to the last possible supply chain location.

Quality product

A product or service that meets customer' expectations and is therefore "fit for purpose"

Package to Order

A production environment in which a good or service can be packaged after receipt of a customer order. The item is common across many different customers; packaging determines the end product.

Assemble-to-Order

A production environment where a good or service can be assembled after receipt of a customer's order. The key components (bulk, semi-finished, intermediate, subassembly, fabricated, purchased, packing, and so on) used in the assembly or finishing process are planned and usually stocked in anticipation of a customer order. Receipt of an order initiates assembly of the customized product. This strategy is useful where a large number of end products (based on the selection of options and accessories) can be assembled from common components.

Make-to-Order

A production environment where a good or service can be made after receipt of a customer's order. The final product is usually a combination of standard items and items custom-designed to meet the special needs of the customer. Where options or accessories are stocked before customer orders arrive, the term assemble-to-order is frequently used. Synonym: produce-to-order. See: assemble-to-order, make-to-stock.

Make-to-Stock

A production environment where products can be and usually are finished before receipt of a customer order. Customer orders are typically filled from existing stocks, and production orders are used to replenish those stocks. Synonym: produce-to-stock. See: assemble-to-order, make-to-order.

Lot

Sawtooth Diagram

A quantity-versus-time graphic representation of the order point/order quantity inventory system showing inventory being received and then used up and reordered.

Milk Run

A regular route for pickup of mixed loads from several suppliers. For example, instead of each of five suppliers sending a truckload per week to meet the weekly needs of the customer, one truck visits each of the suppliers on a daily basis before delivering to the customer's plant. Five truckloads per week are still shipped, but each truckload contains the daily requirement from each supplier. See: consolidation.

Planned Order Release

A row on an MRP table that is derived from planned order receipts by taking the planned receipt quantity and offsetting to the left by the appropriate lead time. See: order release.

FAS - Final Assemble Schedule

A schedule of end items to finish the product for specific customers' orders in a make-to-order or assemble-to-order environment. It is also referred to as the finishing schedule because it may involve operations other than the final assembly; also, it may not involve assembly (e.g., final mixing, cutting, packaging). The FAS is prepared after receipt of a customer order as constrained by the availability of material and capacity, and it schedules the operations required to complete the product from the level where it is stocked (or master scheduled) to the end-item level.

Forward Scheduling

A scheduling technique where the scheduler proceeds from a known start date and computes the completion date for an order, usually proceeding from the first operation to the last. Dates generated by this technique are generally the earliest start dates for operations. See: forward pass. Antonym: back scheduling.

Bar Code

Lot Control

A set of procedures (e.g., assigning unique batch numbers and tracking each batch) used to maintain lot integrity from raw materials, from the supplier through manufacturing to consumers.

MRP - Material Requirements Planning

A set of techniques that uses bill of material data, inventory data, and the master production schedule to calculate requirements for materials. It makes recommendations to release replenishment orders for material. Further, because it is time-phased, it makes recommendations to reschedule open orders when due dates and need dates are not in phase. Time-phased MRP begins with the items listed on the MPS and determines (1) the quantity of all components and materials required to fabricate those items and (2) the date that the components and material are required. Time-phased MRP is accomplished by exploding the bill of material, adjusting for inventory quantities on hand or on order, and offsetting the net requirements by the appropriate lead times.

Unit Load

A shipping unit made up of a number of items, or bulky material, arranged or constrained so the mass can be picked up or moved as a single unit. Reduces material handling costs. Often shrink-packed on a pallet before shipment.

Andon

A sign board with signal lights used to make workers and management aware of a quality, quality, or process problem.

Store

A storage point located upstream of a work station intended to make it easier to see customer requirements.

Random-Location Storage

A storage technique in which parts are placed in any space that is empty when they arrive at the storeroom. Although this random method requires the use of a locator file to identify part locations, it often requires less storage space than a fixed-location storage method. Synonym: floating inventory location system, floating storage location. See: fixed-location storage.

Product Differentiation

A strategy of making a product distinct from the competition on a nonprice basis such as availability, durability, quality, or reliability.

Planned Order

A suggested order quantity, release date, and due date created by the planning system's logic when it encounters net requirements in processing MRP. In some cases, it can also be created by a master scheduling module. Planned orders are created by the computer, exist only within the computer, and may be changed or deleted by the computer during subsequent processing if conditions change. Planned orders at one level will be exploded into gross requirements for components at the next level. Planned orders, along with released orders, serve as input to capacity requirements planning to show the total capacity requirements by work center in future time periods. See: planning time fence.

Closed-loop MRP

A system built around material requirements planning that includes the additional planning processes of production planning (sales and operations planning), master production scheduling, and capacity requirements planning. Once this planning phase is complete and the plans have been accepted as realistic and attainable, the execution processes come into play. These processes include the manufacturing control processes of input-output (capacity) measurement, detailed scheduling and dispatching, as well as anticipated delay reports from both the plant and suppliers, supplier scheduling, and so on. The term closed loop implies not only that each of these processes is included in the overall system, but also that feedback is provided by the execution processes so that the planning can be kept valid at all times.

Back Scheduling

A technique for calculating operation start dates and due dates. The schedule is computed starting with the due date for the order and working backward to determine the required start date and/or due dates for each operation.

I/O - Input/Output Control

A technique for capacity control where planned and actual inputs and planned and actual outputs of a work center are monitored. Planned inputs and outputs for each work center are developed by capacity requirements planning and approved by manufacturing management. Actual input is compared to planned input to identify when work center output might vary from the plan because work is not available at the work center. Actual output is also compared to planned output to identify problems within the work center. Synonym: input/output analysis. See: capacity control.

Lead-time Offset

A technique used in MRP where a planned order receipt in one time period will require the release of that order in an earlier time period based on the lead time for the item. Synonym: component lead-time offset, offsetting.

TQM - Total Quality Management

A term coined to describe Japanese-style management approaches to quality improvement. Since then, total quality management (TQM) has taken on many meanings. Simply put, TQM is a management approach to long-term success through customer satisfaction. TQM is based on the participation of all members of an organization in improving processes, goods, services, and the culture in which they work. The methods for implementing this approach are found in teachings of such quality leaders as Philip B. Crosby, W. Edwards Deming, Armand V. Feigenbaum, Kaoru Ishikawa, J.M. Juran, and Genichi Taguchi.

Cause-and-Effect Diagram

A tool for analyzing process dispersion. It is also referred to as the Ishikawa diagram (because Kaoru Ishikawa developed it) and the fishbone diagram (because the complete diagram resembles a fish skeleton). The diagram illustrates the main causes and subcauses leading to an effect (symptom). The cause-and-effect diagram is one of the seven tools of quality. Synonym: fishbone chart, Ishikawa diagram.

EOQ - Economic Order Quantity

A type of fixed order quantity model that determines the amount of an item to be purchased or manufactured at one time. The intent is to minimize the combined costs of acquiring and carrying inventory. The basic formula is: [please see the print version of APICS Dictionary for full definition] where A = annual usage in units, S = ordering costs in dollars, i = annual inventory carrying cost rate as a decimal, and C = unit cost.

This is caused by the serial nature of communicating orders up the chain with the inherent transportation delays of moving product down the chain. The bullwhip effect can be eliminated by synchronizing the supply chain

Reverse Auction

An internet auction in which suppliers attempt to underbid their competitors. Company identities are known only by the buyer.

Cycle Counting

An inventory accuracy audit technique where inventory is counted on a cyclic schedule rather than once a year. A cycle inventory count is usually taken on a regular, defined basis (often more frequently for high-value or fast-moving items and less frequently for low-value or slow-moving items). Most effective cycle counting systems require the counting of a certain number of items every workday with each item counted at a prescribed frequency. The key purpose of cycle counting is to identify items in error, thus triggering research, identification, and elimination of the cause of the errors.

Quality

Conformance to requirements or fitness for use. Quality can be defined through five principal approaches: (1) Transcendent quality is an ideal, a condition of excellence. (2) Product-based quality is based on a product attribute. (3) User-based quality is fitness for use. (4) Manufacturing-based quality is conformance to requirements. (5) Value-based quality is the degree of excellence at an acceptable price. Also, quality has two major components: (1) quality of conformance—quality is defined by the absence of defects, and (2) quality of design—quality is measured by the degree of customer satisfaction with a product's characteristics and features.

Total Costs

Considering all cost impacts, rather than just one cost impact, on customer service improvement.

Demand Demand Planning

Demand Planning is the recognition of demand and understanding the demand. Drives Operation to determine what is needed, how much is needed and when to produce to meet Priority Plan Demand Planning comes in two forms: 1. Demand Forecasts 2. Management of actual customer orders (internal and external customers)

Dependent Demand

Demand that is directly related to or derived from the bill of material structure for other items or end products. Such demands are therefore calculated and need not and should not be forecast. A given inventory item may have both dependent and independent demand at any given time. For example, a part may simultaneously be the component of an assembly and sold as a service part. See: independent demand.

TPOP - Time-Phased Order Point

MRP-like time planning logic for independent demand items, where gross requirements come from a forecast, not via explosion. This technique can be used to plan distribution center inventories as well as to plan for service (repair) parts, because MRP logic can readily handle items with dependent demand, independent demand, or a combination of both. Time-phased order point is an approach that uses time periods, thus allowing for lumpy withdrawals instead of average demand. When used in distribution environments, the planned order releases are input to the master schedule dependent demands. See: fixed reorder quantity inventory model.

Mixed-Model Production

Making several different parts or products in varying lot sizes so that a factory produces close to the same mix of products that will be sold that day. The mixed-model schedule governs the making and the delivery of component parts, including those provided by outside suppliers. The goal is to build every model every day, according to daily demand.

Forecast Three Principles of Data Collection and Preparation

Most Forecasts are based on historical data, and the collection and preparation of the data for use in forecasting is of utmost importance. It requires judgment and sound analytical skills. 1. Record data in the term needed for the forecast • Record demand with customer request, not sales and order shipments • Use the same forecast periods • Item should match those controlled by manufacturing 2. Record the circumstances relating to the data (promotion, weather, price change, strikes) 3. Record demand separately for different customer group (variation in order cycle/lotsize, record separately to account for the lumpiness of demand)

Average Inventory

One-half the average lot size plus the safety stock, when demand and lot sizes are expected to be relatively uniform over time. The average can be calculated as an average of several inventory observations taken over several historical time periods; e.g., 12-month ending inventories may be averaged. When demand and lot sizes are not uniform, the stock level versus time can be graphed to determine the average.

Yield

The amount of good or acceptable material available after the completion of a process. Usually computed as the final amount divided by the initial amount converted to a decimal or percentage. In manufacturing planning and control systems, yield is usually related to specific routing steps or to the parent item to determine how many units should be scheduled to produce a specific number of finished goods. For example, if 50 units of a product are required by a customer and a yield of 70 percent is expected then 72 units (computed as 50 units divided by .7) should be started in the manufacturing process.

The classification of a group of items in decreasing order of annual dollar volume (price multiplied by projected volume) or other criteria. This array is then split into three classes, called A, B, and C. The A group usually represents 10 percent to 20 percent by number of items and 50 percent to 70 percent by projected dollar volume. The next grouping, B, usually represents about 20 percent of the items and about 20 percent of the dollar volume. The C class contains 60 percent to 70 percent of the items and represents about 10 percent to 30 percent of the dollar volume.

Productivity

1) An overall measure of the ability to produce a good or a service. It is the actual output of production compared to the actual input of resources. Productivity is a relative measure across time or against common entities (labor, capital, etc.). In the production literature, attempts have been made to define total productivity where the effects of labor and capital are combined and divided into the output. One example is a ratio that is calculated by adding the dollar value of labor, capital equipment, energy, and material, and so forth and dividing it into the dollar value of output in a given time period. This is one measure of total factor productivity. 2) In economics, the ratio of output in terms of dollars of sales to an input such as direct labor in terms of the total wages. This is called single factor productivity or partial factor productivity. See: efficiency, labor productivity, machine productivity, utilization.

Reorder Quantity

1) In a fixed-reorder quantity system of inventory control, the fixed quantity that should be ordered each time the available stock (on-hand plus on-order) falls to or below the reorder point. 2) In a variable reorder quantity system, the amount ordered from time period to time period will vary. Synonym: replenishment order quantity.

Value Added

1) In accounting, the addition of direct labor, direct material, and allocated overhead assigned at an operation. It is the cost roll-up as a part goes through a manufacturing process to finished inventory. 2) In current manufacturing terms, the actual increase of utility from the viewpoint of the customer as a part is transformed from raw material to finished inventory. It is the contribution made by an operation or a plant to the final usefulness and value of a product, as seen by the customer. The objective is to eliminate all non-value-added activities in producing and providing a good or service.

Logistics

1) In an industrial context, the art and science of obtaining, producing, and distributing material and product in the proper place and in proper quantities. 2) In a military sense (where it has greater usage), its meaning can also include the movement of personnel.

Total Cost Curve

1) In cost-volume-profit (breakeven) analysis, the total cost curve is composed of total fixed and variable costs per unit multiplied by the number of units provided. Breakeven quantity occurs where the total cost curve and total sales revenue curve intersect. 2) In inventory theory, the total cost curve for an inventory item is the sum of the costs of acquiring and carrying the item. See: economic order quantity, break-even chart, break-even point.

Safety Stock

1) In general, a quantity of stock planned to be in inventory to protect against fluctuations in demand or supply. 2) In the context of master production scheduling, the additional inventory and capacity planned as protection against forecast errors and short-term changes in the backlog. Overplanning can be used to create safety stock. Synonym: buffer stock, reserve stock. See: hedge, inventory buffer.

Cycle Time

1) In industrial engineering, the time between completion of two discrete units of production. For example, the cycle time of motors assembled at a rate of 120 per hour would be 30 seconds. 2) In materials management, it refers to the length of time from when material enters a production facility until it exits. Synonym: throughput time.

Service Industry

1) In its narrowest sense, an organization that provides an intangible product (e.g., medical or legal advice). 2) In its broadest sense, all organizations except farming, mining, and manufacturing. This definition of service industry includes retail trade; wholesale trade; transportation and utilities; finance, insurance, and real estate; construction; professional, personal, and social services; and local, state, and federal governments.

Push System

1) In production, the production of items at times required by a given schedule planned in advance. 2) In material control, the issuing of material according to a given schedule or issuing material to a job order at its start time. 3) In distribution, a system for replenishing field warehouse inventories where replenishment decision making is centralized, usually at the manufacturing site or central supply facility. See: pull system.

Pull System

1) In production, the production of items only as demanded for use or to replace those taken for use. 2) In material control, the withdrawal of inventory as demanded by the using operations. Material is not issued until a signal comes from the user. 3) In distribution, a system for replenishing field warehouse inventories where replenishment decisions are made at the field warehouse itself, not at the central warehouse or plant. See: pull signal.

Level Schedule

1) In traditional management, a production schedule or master production schedule that generates material and labor requirements that are as evenly spread over time as possible. Finished goods inventories buffer the production system against seasonal demand. 2) In JIT, a level schedule (usually constructed monthly) in which each day's customer demand is scheduled to be built on the day it will be shipped. A level schedule is the output of the load-leveling process. Synonym: JIT master schedule, level production schedule. See: load leveling, level production method.

Theory of Constraints Accounting

A cost and managerial accounting system that accumulates costs and revenues into three areas—throughput, inventory, and operating expense. It does not create incentives (through allocation of overhead) to build up inventory. The system is considered to provide a truer reflection of actual revenues and costs than traditional cost accounting. It is closer to a cash flow concept of income than is traditional accounting. The theory of constraints (TOC) accounting provides a simplified and more accurate form of direct costing that subtracts true variable costs (those costs that vary with throughput quantity). Unlike traditional cost accounting systems in which the focus is generally placed on reducing costs in all the various accounts, the primary focus of TOC accounting is on aggressively exploiting the constraint(s) to make more money for the firm. Synonym: constraint accounting, throughput accounting.

Extrinsic forecasts tend to be more useful for large aggregations, such as total company sales, than for individual product sales. Antonym: intrinsic forecast method. See: quantitative forecasting technique.

Hedge Inventory

A form of inventory buildup to buffer against some event that may not happen. Hedge inventory planning involves speculation related to potential labor strikes, price increases, unsettled governments, and events that could severely impair a company's strategic initiatives. Risk and consequences are unusually high, and top management approval is often required.

Intermittent Production

A form of manufacturing in which the jobs pass through the functional departments in lots, and each lot may have a different routing. See: job shop.

Capital intensive

High proportion of capital (machinery) compared to labour

Labour intensive

Three types of buffers in Theory of constraints are

I. Time Buffers II. Stock Buffers III. Protective capacity

Demonstrated Capacity

If over the previous 4 weeks, a work center produced 110, 140, 120, 130 standard hours of work, what is the demonstrated weekly capacity? =110+140+120+130 4 = 125 hours

Pegging

In MRP and MPS, the capability to identify for a given item the sources of its gross requirements and/or allocations. Pegging can be thought of as active where-used information. See: requirements traceability.

Net Requirements

In MRP, the net requirements for a part or an assembly are derived as a result of applying gross requirements and allocations against inventory on hand, scheduled receipts, and safety stock. Net requirements, lot-sized and offset for lead time, become planned orders.

Performance Standard

In a performance measurement system, the accepted, targeted, or expected value for the criterion. See: performance criterion, performance measure, performance measurement system.

Heijunka

In just-in-time philosophy, an approach to level production throughout the supply chain to match the planned rate of end product sales.

Uniform Plant Loading

In lean, the distribution of work between work stations so that the time required for each station to complete all tasks is as close to equal as possible. See: line balancing.

Pacemaker

In lean, the resource that is scheduled based on the customer demand rate for that specific value stream. It is that resource which performs an operation or process that governs the flow of materials along the value stream. Its purpose is to maintain a smooth flow through the manufacturing plant; a larger buffer is provided for the pacemaker than other resources so that it can maintain continuous operation. See: constraint.

Flow Processing

In process systems development, work flows from one workstation to another at a nearly constant rate and with no delays. When producing discrete (geometric) units, the process is called repetitive manufacturing; when producing non-geometric units over time, the process is called continuous manufacturing. A physical-chemical reaction takes place in the continuous flow process.

Modularization

In product development, the use of standardized parts for flexibility and variety. Permits product development cost reductions by using the same item(s) to build a variety of finished goods. This is the first step in developing a planning bill of material process.

Start Date

In project management, the time an activity begins; this may be defined as an actual start date or a planned start date.

TCO - Total Cost of Ownership

In supply chain management, the total cost of ownership of the supply delivery system is the sum of all the costs associated with every activity of the supply stream. The main insight that TCO offers to the supply chain manager is the understanding that the acquisition cost is often a very small portion of the total cost of ownership.

Critical Chain Method

In the theory of constraints, a network planning technique for the analysis of a project's completion time, used for planning and controlling project activities. The critical chain, which determines project duration, is based on technological and resource constraints. Strategic buffering of paths and resources is used to increase project completion success. See: critical chain, critical path method.

Days of Supply

Inventory-on-hand metric converted from units to how long the units will last. For example, if there are 2,000 units on hand and the company is using 200 per day, than there are 10 days of supply.

VATI Analysis

In the theory of constraints, a procedure for determining the general flow of parts and products from raw materials to finished products (logical product structure). Once the general parts flow is determined, the system control points (gating operations, convergent points, divergent points, constraints, and shipping points) can be identified and managed. - A V logical structure starts with one or a few raw materials, and the product expands into a number of different products as it flows through divergent points in its routings. - The shape of an A logical structure is dominated by converging points. Many raw materials are fabricated and assembled into a few finished products. - A T logical structure consists of numerous similar finished products assembled from common assemblies, subassemblies, and parts. - An I logical structure is the simplest of production flows, where resources are shared between different products and the flow is in a straight line sequence, such as an assembly line.

Buffer Management

In the theory of constraints, a process in which all expediting in a shop is driven by what is scheduled to be in the buffers (constraint, shipping, and assembly buffers). By expediting this material into the buffers, the system helps avoid idleness at the constraint and missed customer due dates. In addition, the causes of items missing from the buffer are identified, and the frequency of occurrence is used to prioritize improvement activities.

Five Focusing Steps

In the theory of constraints, a process to continuously improve organizational profit by evaluating the production system and market mix to determine how to make the most profit using the system constraint. The steps consist of (1) identifying the constraint to the system, (2) deciding how to exploit the constraint to the system, (3) subordinating all nonconstraints to the constraint, (4) elevating the constraint to the system, (5) returning to step 1 if the constraint is broken in any previous step, while not allowing inertia to set in.

Protective Inventory

In the theory of constraints, the amount of inventory required relative to the protective capacity in the system to achieve a specific throughput rate at the constraint. See: limiting operation.

Productive Capacity

In the theory of constraints: The maximum of the output capabilities of a resource (or series of resources) or the market demand for that output for a given time period. See: excess capacity, idle capacity, protective capacity.

Terminals

In transportation, locations where carriers load and unload goods to and from vehicles. Also used to make connections between local pickup and delivery service and line-haul service. Functions performed in terminals include weighing connections with other routes and carriers, vehicle routing, dispatching, maintenance, paperwork, and administration. Terminals may be owned and operated by the carrier or the public.

Order Qualifiers

Those competitive characteristics that a firm must exhibit to be a viable competitor in the marketplace. For example, a firm may seek to compete on characteristics other than price, but in order to "qualify" to compete, its costs and the related price must be within a certain range to be considered by its customers. Synonym: qualifiers. See: order losers, order winners.

Order Winners

Those competitive characteristics that cause a firm's customers to choose that firm's goods and services over those of its competitors. Order winners can be considered to be competitive advantages for the firm. Order winners usually focus on one (rarely more than two) of the following strategic initiatives: price/cost, quality, delivery speed, delivery reliability, product design, flexibility, after-market service, and image. See: order losers, order qualifiers.
