Tactical Planning

The process of developing a set of tactical plants (e.g., production plan, sales plan, marketing plan, and so on).  Two approaches to tactical planning exist for linking tactical plans to strategic plans – production planning and sales and operations planning. 

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.

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 is 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.

Tank Container

Tare Weight

Tare Weight of Container

Mass of an empty container including all fittings and appliances associated with that particular type of container on its normal operating condition.

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 date

A projected start or finish date for a project task. 

Target pricing

Time Charter
