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 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 constrainst accounting provides a simplified and more accurate form of direct costing that subtracts true variable costs. Unlinke traditional cost accounting systems in which the focus is generally placced on reducting costs in all the various accounts, the primary focus of TOC accounting is on aggressively exploiting the constraints to make more money for the firm

The function of routing and sipatching the owkr to be accomplished through the production facility and of performing supplier control. PAC encompasses the principles, approaches, and techniques needed to schedule, control, measure, and evaluate the effectiveness of production operations
Field Service
The functions of installing and maintaing a product for a customer after the sale or during the lease. Field service may also include training and implementation assistance
Supply Chain
The global network used to deliver products and services from raw materials to end customers through an engineered flow of information, physical distribution, and cash
Materials Management
The grouping of management functions supporting the complete cycle of material flow, from the purchase and internal control of production materials to the planning and control of work in process to the warehousing, shipping and distribution of the finished product
Freight Consolidation
The grouping of shipments to obtain reduced costs or improved utilization of the transportation function. Consolidation can occur by market area grouping, grouping according to scheduled deliveries, or using 3pl services such as public warehouses and freight forwarders
Standard Time
The length of time that should be requiered to 1) set up a given machine or operation and 2) run one batch or one or more parts, assemblies, or end products through that operation. This time is ued in determining machine requirements and labor requirements. Standard time assumes an average worker following prescribed methods and allows for personal rest to overcome fatigue and unavoidable delays. It is also frequently used as a basis for incentive pay systems and as a basis of allocating overhead in cost accounting systems
Break-Even Point
The level of production or the volume of sales at which operations are neither profitable nor unprofitable. The break even point is the intersection of the total revenue and total cost curves.
Cumulative Lead Time
The longest planned length of time to accomplish the activity in question. It is found by reviewing the lead time for each BOM path below the item; whichever path adds up to the greatest number defines cumulative lead time
Master Production Schedule (MPS)
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 a company plans to produce, expressed in specific configs, quantities and dates. Not a sales forecast, but takes into account the forecast, production plan, backlog etc.
Freight Forwarder
The middle man between the carrier and the organization shipping the product. Often combines smaller shipments to take advantage of lower bulk costs.
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, investments. Also called cash proceeds or cash generated.
Available Inventory
The on-hand inventory balance minus allocations, reservations, backorders, and (usually) quantities held for quality problems. Often called beginning available balance (syn. beginning available balance, net inventory)
Flowchart

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 faulure 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

Demand Planning
The process of combining statistical forecasting techniques and judgement to construct demand estimates for products or services across the supply chain from the suppliers raw materials to the consumers 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 judgement from market. Actual sales are compared with forecasts provided by various models to determine which techniques minimize forecast error.
Capacity 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. The resulting delivery date takes into account consideration production capacity, current manufacturing environment and future order commitments. The objective is to reduce time spent by production planners in expediting orders.
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
Rough-Cut Capacity Planning (RCCP)
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. These approaches to performing RCCP are hte bill of labor approach, the capacity planning using overall factors approach, and the resource profile approach.
