|Individual pieces of data in a database, on a report, or on a computer screen. Individual fields in a database file such as the item number or quantity from an inventory record are examples of data elements.
|The specific way data elements are displayed or printed on a report or computer screen. Data formatting not only includes the font and style (bold, italics, etc.) of the text but also the inclusion of spaces or special characters to make the data element more readable.
|A character or set of characters added to a bar code to identify the type of data included in the bar code.
|Term that describes the “filtering” of data to only display certain records on reports or computer screens. Setting a count program to only release counts for a specific aisle is an example of data selection.

|Abbreviation for Distribution Centre
|Abbreviation for “Destination Delivery Charge.” A charge, based on container size, that is applied in many tariffs to cargo. This charge is considered accessorial and is added to the base ocean freight. This charge covers crane lifts off the vessel, drayage of the container within the terminal and gate fees at the terminal operation.
|Refers to any part of the transportation trip in which no freight is being carried.
|The number of tons of 2,240 pounds that a vessel can transport of cargo, stores and bunker fuel. It is the difference between the number of tons of water a vessel displaces “light” and the number of tons it displaces when submerged to the “load line.”
|A matrix teams use to evaluate problems or possible solutions. For example, a team might draw a matrix to evaluate possible solutions, listing them in the far left vertical column. Next, the team selects criteria to rate the possible solutions, writing them across the top row. Then, each possible solution is rated on a scale of 1 to 5 for each criterion, and the rating is recorded in the corresponding grid. Finally, the ratings of all the criteria for each possible solution are added to determine its total score. The total score is then used to help decide which solution deserves the most attention.

Decoders are often called wedges because they frequently use a keyboard wedge interface to connect and communicate with a computer or terminal. The decoder will convert the scanner output into ASCII characters and then pass this data to your computer.
|Place where loose or other non-containerised cargo is ungrouped for delivery.
|A product’s or service’s nonfulfillment of an intended requirement or reasonable expectation for use, including safety considerations. There are four classes of defects: class 1, very serious, leads directly to severe injury or catastrophic economic loss; class 2, serious, leads directly to significant injury or significant economic loss; class 3, major, is related to major problems with respect to intended normal or reasonably foreseeable use; and class 4, minor, is related to minor problems with respect to intended normal or reasonably foreseeable use.

All dimensional measurements are in inches.
|See pallet dimensions.
|Via the route of a single carrier.
|Direct shipping and drop shipping are two terms generally used interchangeably. They describe a process whereby three parties interact with the sales transaction (the buyer, the seller, and the supplier). The buyer initiates a purchase from the seller, who then arranges with the supplier to ship the product directly to the buyer. The seller does not carry inventory of the product and the supplier does not have any direct communication with the buyer. The buyer pays the seller and the seller pays the supplier. Though both terms (direct ship and drop ship) are generally used to describe the same process, I’ve always considered a small distinction between the two that relates to where you are in the supply chain. To the seller, direct shipping describes both the process and an inventory/sales strategy, however, the supplier will frequently just use the term “drop ship” to describe the process whereby he is shipping the product to an address other than that of his customer (the business that is paying him for the product). Sometimes the term drop ship also describes the process of shipping to any location that is different from the customer’s normal shipping location. This subtle distinction is sometimes evident in the terminology used in software documentation. Direct shipment, Drop shipment.
|Printing method used to produce bar code labels. Direct thermal uses a heated print head to darken areas on special thermal activated label stock.
|Tasks that can be completed based upon detailed information provided by the computer system. An order picking task where the computer details the specific item, location, and quantity to pick is an example of a directed task. If the computer could not specify the location and quantity forcing the worker to choose locations or change quantities, it would not be a directed task. Directed tasks set up the opportunity for confirmation transactions.
|Discrepancy Letter of Credit
|When documents presented do not conform to the requirements of the letter of credit (L/C), it is referred to as a “discrepancy.” Banks will not process L/C’s which have discrepancies. They will refer the situation back to the buyer and/or seller and await further instructions.
|Describes manufacturing of distinct items (items you can easily count, touch, see) such as a pencil, a light bulb, a telephone, a bicycle, a fuel pump, etc. Discrete as opposed to Process manufacturing. Also see Process Manufacturing.
