Taguchi Method
A concept of offline quality control methods conducted at the product and process design states in the product development cycle. This concept, expressed by Genichi Taguchi, encompasses three phases of product design, parameter design, and tolerance design. The goal is to reduce quality loss by reducing the variability of a product’s characteristics during the parameter phase of product development.
Takeaway conveyor
A powered conveyor (e.g., belt or live roller) used in piece and case picking to transport completed orders.
Takt Time
Sets the pace of production to match the rate of customer demand and becomes the heartbeat of any lean production system. It’s computed as the available production time divided by the rate of customer demand. For example, assume demand is 10,000 units per month, or 500 units per day and planned available capacity are 420 minutes per day. The takt time = 420 minutes per day/500 units per day = 0.84 minutes per unit. This takt time means that a unit should be planned to exit the production system on average every 0.84 minutes.
Tare Weight
The weight of a substance obtained by deducting the weight of the empty container from the gross weight of the full container.
Target Costing
A target cost is calculated by subtracting the desired profit margin from an estimated or market-based price to arrive at a desired production, engineering, or marketing cost. This may not be the initial production cost, but one expected to be achieved during the mature production stage. Target costing is a method used in the analysis of product design that involves estimated a target cost, then designing the product/service to meet that cost.
Target stock level
determines the order size for a periodic review method (with order size equal to target stock level minus current stock minus amount already on order)
Tariff
A tax assessed by a government on goods entering or leaving a country. The term is also used in transportation in reference to the fees and rules applied by a carrier for its services.
Task interleaving
Term used in describing a warehouse management systems to mix tasks to reduce travel time. Sending a forklift driver to put away a pallet on his way to his next pick is a task interleaving example.
Tasks
The breakdown of the work in an activity into smaller elements.
Tender
The document which describes a business transaction to be performed.
Theory of Constraints (TOC)
A production management theory which dictates that volume is controlled by a series of constraints related to work center capacity, component availability, finance, etc. Total throughput cannot exceed the capacity of the smallest constraint, and any inventory buffers or excess capacity at non-related work center is waste.
Third Party Logistics
Outsourcing all or much of a company’s logistics operations to a specialized company.
Third Party Logistics Provider (3PL)
A firm which provides multiple logistics services for use by customers. Preferably, these services are integrated or bundled together, by the provider. These firms facilitate the movement of parts and materials from suppliers to manufacturers, and finished products from manufacturers, and finished products from manufacturers to distributors and retailers. Among the services they provide are transportation, warehousing, cross docking, inventory management, packaging, and freight forwarding.
Third Party Warehousing
The outsourcing of the warehousing function by the seller of the goods.
Throughput
A measure of warehousing output volume (weight, number of units). Also, the total amount of units received, plus the total amount of units shipped divided by two.
Tier 1, 2 supplier
A tier 1 supplier is the immediate or primary set of vendors directly used by a company, and tier 2 is a vendor to tier 1. In some industries the final customers or dominant chain partners are consolidating (reducing) their number of tier 1 suppliers, and requiring proof of the communications and fulfillment capabilities between tier 1 and tier 2.
Total Annual Sales
Total Annual Sales are Total Product Revenue plus post-delivery revenues (e.g., maintenance and repair or equipment, system integration) royalties, sales of other services, spare parts revenue, and rental/lease revenues.
Total Average Inventory
Average normal use stock, plus average lead stock, plus safety stock.
Total Cost Analysis
A decision-making approach that considers minimization of total costs and recognizes the inter-relationship among system variables, such as transportation, warehousing, inventory, and customer service.
Total Cost Curve
1) In cost-volume-profit (break-even) analysis, the total cost curve is composed of total fixed and variable costs per unit multiplied by the number of units provided. Break-even 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.
Total Cost of Ownership (TCO)
Total cost of a computer asset throughout its life cycle, from acquisition to disposal. TCO is the combined hard and soft costs of owning networked information assets. “Hard” costs include items such as the purchase price of the asset, implementation fees, upgrades, maintenance, contracts, support contracts, disposal costs, and license fees that may or may not be up-front or charged annually. These costs are considered “hard costs” because they are tangible and easily accounted for.
Total Cumulative Manufacture Cycle Time
Average time between commencement of upstream processing and completion of final packaging for shipment operations as well as release of approval for shipment. Does not include WIP storage time.Calculation: [Average # of units in WIP]/[Average daily output in units] – WIP days of supply
Total Make Cycle Time
The average processing time between commencement of upstream processing and completion of all manufacturing process steps up to, but not including, packaging and labeling operations (i.e., from start of manufacturing to final formulated product ready for primary packaging.) Does not include hold or test and release times. Calculation: [Average # of units in active manufacturing]/[Average daily output in units.]
Total Product Revenue
The total value of sales made to external customers plus the transfer price valuation of intra-company shipments, net of all discounts, coupons, allowances, and rebates. Includes only the intra-company revenue for product transferring out of an entity, installation services if these services are sold bundled with end products, and recognized leases to customers initiated during the same period as revenue shipments, with revenue credited at the average selling price.
Note: Total Product Revenue excludes post-delivery revenues (maintenance and repair of equipment, system integrations), royalties, sales of other services, spare parts revenue, and rental/lease revenues.
Total Productive Maintenance (TPM)
Team-based maintenance process designed to maximize machine availability and performance and product quality.
Total Quality Management
a management strategy that focuses on continuous improvement.
Total Supply Chain Management Cost (five elements)
Total cost to manage order processing, acquire materials, manage inventory, and manage supply chain finance, planning, and IT costs as represented as a percent of revenue. Accurate assignment of IT-related cost is challenging. It can be done using activity-based costing methods, or more traditional-based approaches. Allocation based on user counts, transaction counts, or departmental headcounts are reasonable approaches. The emphasis should be on capturing all costs, whether incurred in the entity completing the survey or in a supporting organization on behalf of the entity. Reasonable estimates founded in data were accepted as means to assess overall performance. All estimates reflected fully-burdened actuals inclusive of salary, benefits, space and facilities, and general and administrative allocations.
Calculation: [Order Management Costs + Material Acquisition Costs + Inventory Carrying Costs + Supply-Chain Related Finance and Planning Costs + Total Supply Chain-Related IT Costs]/[Total Product Revenue]
Total Supply Chain Response Time
The time it takes to rebalance the entire supply chain after determining a change in market demand. Also, a measure of a supply chain’s ability to change rapidly in response to marketplace changes.
Calculation: [Forecast Cycle Time] + [Re-Plan Cycle Time] + [Intra-Manufacturing Re-Plan Cycle Time] + [Cumulative Source/Make Cycle Time] + [Order Fulfillment Lead Time]
Total Test Release Cycle Time
The average total test and release time for all tests, documentation reviews, and batch approval processes performed from start of manufacturing to release of final packaged product for shipment.
Calculation: [Average number of units in test and release]/[Average daily output in units]
