How information system are helping in the company(part1)

v RFID System:

Helps in keeping track of the goods for both Wal-Mart and the supplier and helps in saving time and effort and reducing the number of workers.

v Point-of-sale system (POS):

Helps in handling information efficiently and effective use of information which helps Wal-Mart avoid overstocking by learning what merchandise is selling slowly and also provides better inventory management.

v Telecommunications:

This allows automatic reordering and better coordination. Knowing exactly what is selling well and coordinating closely with suppliers permits Wal-Mart to tie up less money in inventory than many of their competitors. At its computerized warehouses, many goods arrive and leave without ever sitting on a shelf. Only10% of the floor space in Wal-Mart stores is used as an inventory area, compared to the 25% average for the industry.

   Point-of-sale system (POS ):

A computerized system that identifies each item sold, finds its price in a computerized database, creates an accurate sales receipt for the customer, and stores this item-by-item sales information for use in analyzing sales and reordering inventory.

Over one 5 year period, Wal-Mart invested over $600 million in information systems.

Telecommunications:

Wal-Mart use telecommunications to link directly from its stores to its central computer system and from that system to its supplier's computers.
