Tactical Planning: Development process of a set of tactical plants (e.g., production plan, sales plan, marketing plan, etc.). Two tactical planning strategies exist to connect tactical plans to strategic plans-production planning and sales and planning operations.

Taguchi Method: In the product development cycle, a definition of offline quality control approaches implemented at the product and process design states. The term, articulated by Genichi Taguchi, covers three stages of product design, design of parameters and design of tolerances. The aim is to reduce loss of quality by reducing the variability of the characteristics of a product during the product development parameter process.

Takt Time: Sets the production rate to suit the customer demand rate and becomes the engine of any lean manufacturing program. It is measured as the production time available divided by the demand rate of the customer. For example, suppose the demand is 10,000 units a month, or 500 units per day, and the planned capacity available is 420 minutes per day. Takt time= 420 minutes a day / 500 units a day= 0.84 minutes a day. This takt time means a unit should be scheduled to take every 0.84 minutes to exit the production system.


Tare code

Tare Weight: The weight of a product derived from the gross weight of the complete container by deduction of the weight of the empty container.

Target Costing: A target cost is determined by extracting the required profit margin from an estimated or market-based price to reach the desired cost of manufacturing, development or marketing. This may not be the initial cost of production, but it is anticipated that this will be done during the mature stage of production. Goal costing is a process used in the analysis of product design involving an estimated goal cost and then the product / service being designed to meet that cost.

Theory of Constraints (TOC): A manufacturing management theory that dictates that volume is limited by a set of constraints related to work center efficiency, availability of materials, finance, etc. Maximum throughput can not surpass the capacity of the smallest limit, and any non-related work center inventory buffers or excess capacity is waste.

Third Party Logistics: Outsourcing all or much of the logistics activities of a company to a specialist business.

Third Party Logistics Provider (3PL): A business that offers various logistics facilities for clients to use. Both programs are ideally combined by the supplier, or bundled together. Such organizations facilitate the flow of parts and materials from suppliers to producers, and finished goods from manufacturers to distributors and retailers. Transportation, warehousing, cross loading, inventory management, packing and freight forwarding are amongst the services they provide.

Third Party Warehousing: The seller of the products has to outsource the warehousing task.

Throughput: A measure of volume of the warehousing production (weight, unit number). In addition, the total number of units earned, plus the total number of units shipped divided by two.

Total Average Inventory: Average standard stock of use, plus average lead stock, plus safety stock.

Total Cost Analysis: A decision-making technique that considers reducing total costs and acknowledges the interrelationship between device variables, such as transport, warehousing, inventory and customer service.

Total Cost Curve: 1) The total cost-volume-profit (break-even) analysis consists of total fixed and variable unit costs multiplied by the number of units given. Quantity break-even occurs when the total cost curve and the total sales revenue curve overlap .2) The total cost curve for an inventory item in inventory theory is the amount of the cost of acquiring and transporting the item.

Total Cost of Ownership (TCO): Software product total cost throughout its life cycle, from purchase to disposal. TCO is the total cost of owning networked information properties, hard and soft. “Hard” costs include things such as the asset purchase price, execution fees, repairs, servicing, contracts, service contracts, disposition costs and license fees which may or may not be upfront or paid quarterly. As they are measurable and easily accounted for, these costs are called “hard costs.”

Total Cumulative Manufacture Cycle Time: Average time between start of upstream processing and finalization of final packaging for shipment operations as well as release of shipment approval. Does not include storage time at WIP.

Total Make Cycle Time: The average processing time between the start of the upstream processing and the completion of all manufacturing process steps up to, but not including, packaging and labeling operations (i.e., from the beginning of manufacturing to the final formulated product ready for primary packaging).

 Total Product Revenue: The total value of sales made to foreign customers plus intra-company shipment transfer price cost, net of all discounts, coupons, bonuses and rebates.

Total Supply Chain Management Cost (five elements): Total cost of handling order management, purchasing products, controlling inventories and managing supply chain finance, preparing and IT costs as a percentage of revenue. The precise distribution of IT related costs is difficult. It can be achieved using costing methods based on the task, or more conventional approaches. Fair methods are allocation based on user amounts, transaction counts, or department headcounts. The emphasis should be on collecting all the costs, whether incurred on behalf of the company conducting the survey or in a supporting organization. Fair data based projections were embraced as a way of evaluating overall performance. All figures represented full-burdened reals like wages, insurance, room and services, and general and administrative allocations.

Total Supply Chain Response Time: The time it takes to rebalance the entire supply chain once a shift in market demand has been calculated. In addition, a measure of the capacity of a supply chain to rapidly adapt in response to market changes.
