This document discusses Walmart's information systems and how they contributed to the company's success. It describes how Walmart invested heavily in technologies like barcode scanning, satellite communications, data warehouses, and retail link to track inventory, sales, and replenish stores. This real-time data sharing with suppliers through EDI improved forecasting and replenishment. Walmart's information systems transformed its supply chain operations and enabled it to grow rapidly while reducing costs.

2. 
Information system:
 Set of interrelated components
 Collect, process, store, and distribute information
 Support decision making, coordination, and
control

Information vs. data
 Data are streams of raw facts
 Information is data shaped into meaningful form

3. 
System that provides information needed to
manage organizations effectively and
efficiently.

4. 
To improve the Management decision
making

By providing accurate and up-to-date
information about the key aspects of
organizational performance.

5. SAM WALTON (MARCH 29, 1918
– APRIL 5, 1992)
a businessman from
Arkansas, began his retail
career when he started work
on June 3, 1940.
 On July 2, 1962, Walton
opened the first Walmart
Discount City store located at
719 Walnut Ave. in Rogers
Arkansas.
 Has undergone several
changes in its
image(specifically logos)


6. 



WalMart is the largest and most profitable
retailer on the earth
the Worlds second largest public corporation
Walmart has 8,500 stores in 15 countries,
under 55 different names
And have around 2 Million employees

7. 
We save people money so they can live better

9. 
This phenomenal growth of Walmart is
attributed to its continued focus on customer
needs and reducing cost through efficient
SCM Practices.

10. 
Walmart invested heavily in IT and
communication systems
 to effectively track sales and merchandise
inventories in stores across the country.

With the rapid expansion,
 it was essential to have a good communication
system.

Hence, Walmart set up its own satellite
communication system in 1983.

11. 
Employees at the stores had the
“Magic Wand,” a hand-held computer which
was linked to in-store terminals through a
radio frequency network.

These helped them to keep track of the
inventory in stores, deliveries, and backup
merchandise in stock at the distribution
centers.

12. 
In the early 1970’s Walmart introduced the
centralized distribution system.
HUB & SPOKE

Goods were centrally ordered, assembled at a
massive warehouse, known as ‘distribution
center’ (hub), then dispatched to the
individual stores (spoke).

13. 
The hub and spoke system enabled Walmart
to achieve significant cost advantages by the
centralized purchasing of goods in huge
quantities;

14. 
Order management and store replenishment
of goods were entirely executed with the help
of computers through the Point-of-Sales
(POS) system.

Through this system, it was possible to
monitor and track the sales and merchandise
stock levels on the store shelves.

15. 
Since the floor area of any Walmart store
varied between 40,000 to 200,000 square
feet, movement of goods within the store
was an important part of logistics operations.

Walmart made significant investments in IT
to quickly locate and replenish goods at the
stores.

16.  In 1991, Walmart had invested approximately $4
billion to build a retail link system.
 More than 10,000 Walmart retail suppliers used
the retail link system to monitor the sales of their
goods at stores and replenish inventories.
 Details of daily transactions (~10 million per day)
were processed through this system.

17. 

Jane data center is the data center of WalMart which has a capacity of 460 terabytes of
data
it has helped Wal-Mart become the biggest
retailer in the world,

19. 
According to the econometric society, WalMart deals with the following data:
 Store openings data
 Store closing data

It also used a software Called GAUSS DATA
SETS for its TPS. Which included:
 Sales
 Operating profits
 Distribution miles

20. When UNIVERSAL BARCODE was
established the manufacturers adopted a
common labelling
 Wal-Mart became very good at using the
information behind the bar code due to its
sophisticated technology to track inventory.
(as we have discussed earlier in the in the
Presentation)


21. 
Professor Edna Bonacich put it simply:
 "The shift in Wal-Mart's power was when it started
to really develop its control over information
technology”


The key to that was the power of the
information that is hidden in the bar code.
No one has used the technology as
efficiently as Wal-Mart.

22. 


The input of TPS is raw data
The processing involves with the
summarizing, recording, and merging the
data and the output is in the form of report.
Example of TPS is Point-of-sales.

23. 

At the supermarket, the cashier has to scan
the product with the bar code that the input
of system.
To use the Barcode the company has to
develop Universal Product Code (UPC)

24. 

a standard method for identifying products
with numbers and coding those numbers as
the type of bar code.
And it had many benefits found by Wal-Mart,
were it
– Ensure accurate pricing
– Improve efficiency
– Reduce Shrinkage
– Improve communications

25. 1. Data collected and
analyzed
 2.Observing Merchand
-ise flow, overstock,
discount
 3. Video transmissions,
credit card
authorizations, and
inventory control


26. 

MIS is the system provides the actual
performance report of the company that use
in middle management, which created based
on the data from TPS.
They use a tool called EDI for the MIS

27. 

EDI enabled the suppliers to download
purchase orders along with store-to-store
sales information relating to their products
sold.
On receiving information about the sales of
various products, the suppliers shipped the
required goods to Walmart’s distribution
centers

28. EDI is Used for:
1.Forecasting
2.Planning
3.Replenishing
4.Shipping applications

29. 

DSS should be the effectiveness of decision
makers rather than on increasing the efficiency
of data storage and retrieval.
Some of the benefits of DSS are as follows.
1.DSS improves individual productivity.
2.it improves the decision quality and speed up problem
solving.
3.it improves interpersonal communications.
4. it improves decision making skills.
5. Increase organizational control

30. 
A number of strategic DSS has been
implemented. Which are as follows:
 sale data warehouse .
 including retail link

Walmart collects sales data from stores in its
data warehouse ,

Retail link consolidated data into useful
reports and distributes it to suppliers with
weekly forecasting information .

31. 


It's awesome the way Walmart control its
information system.
Its accurate enough manage everything.
The Satellite System is perfect in collect
information & share it easily between the
supplier and Walmart.
