Introduction
Supply chain plays a significant role in the life cycle of an organization. With the help of
supply chain, many products and information travel in an organization. The organization can
take effective management on supply chain with the help of control over the web or the
network on resources and participants. An organization whether service based or product
based can take out maximum benefit with the supply chain if they have full and effective
control over its internal capabilities and external resources. On the other hand, Supply chain
management is the designing of all actions in relation to supply chain network so that to
maximise the customer satisfaction and achieve a competitive edge in the industry
(Srivastava, 2007).

Walmart is an American multinational retail organization, established back in 1962 by Sam
Walton. This retail chain runs on big discount department stores and warehouse stores. It is
also one of the fastest developing organization in supply chain and retail management.
According to Forbes (2017), Wal-Mart is on rank 24 in the list of world largest public
companies. Wal-Mart headquarter is situated in Bentonville, Arkansas. As per the year 2018,
the company have around 11,718 stores worldwide with over 2.3 million employees.
Walmart food product category includes various items related to grocery, snacks and
beverages, organic certified foods, baked foods, frozen foods, coffee, meat, cookies and many
more.
The distinctive competitive advantage of Wal-Mart is due to their targeting strategy as the
company targets small and rural communities that help them in lowering the operating cost

(Kampf, 2007). In addition to this, their store location strategy is also innovative; however,
various other aspects have played a significant role in making the company a top retail
mountain chain. The vision statement of Wal-Mart is short and clear, as they want to save
people money to help them in living a better life. In addition to this, the founder i.e. Sam
Walton also said that “if well all work together, the cost of living for everyone can be
decreased and the world will get an opportunity to realise how can everyone live with a better
life (Hollenbeck and Zinkhan, 2010).

This supply chain diagram states various relationship from the processing of the raw
materials to the fulfillment of the demand of various markets. The major four nodes of this
supply chain are Suppliers, manufacturers, distribution centres and demand markets
(Craighead et al, 2007).
Sam Walton established the chain of Wal-Mart Stores back in 1962. As Wal-Mart developed
in the 1960s to 1980s, the company starts taking the advantage of the better transportation
facilities and other resources. They have several strengths in their supply chain, which
includes RFIDS deployment, in-house transit engagement, digital technology to manage sales
inventory, and share sales information with suppliers.
Their supply chain focused on several functions, which includes purchasing of the products
from the suppliers, reducing the distribution cost, choosing the best transit mode and
formulating retail strategy so that the product can be sold at the bulk level. These retail
strategies include all the activities from logistic level to store level with addition to reduction
in the operational cost. This strategic and intellectual supply chain of Wal-Mart helps the
company in getting significant share within the US stock market (Neumark, Zhang and
Ciccarella, 2008).
In the supply chain of Wal-Mart, the vendor (suppliers) administered the level of stocks and
availability for the customer. This starts the distribution with the help of VMI, which stands
for Vendor Managed Inventory. In this inventory system, the vendor is accountable for
sustaining the customer stock levels (Darwish, and Odah, 2010). This is the first stage of the
company towards the supply chain collaboration, which also increased speed and service.
In their distribution channel, the company plans strategy regarding reshaping the cost
structure so that to advanced their supply chain management by enhancing competitive
advantage. Walmart innovation already started back in 1980s, where the company starts
working directly with the manufacturers to cut the cost at various places and managing the
supply chain in an efficient manner. They also plan for the strategic sourcing where they
started to prioritize the suppliers which are in a position to match the customer demand in a
timely manner. They started makes a strategic partnership with the various vendors who have
the potential for long terms work and relationship in exchange of lowest possible prices

SUPPLY CHAIN 6
(Ketchen and Hult, 2007). This makes the smoother flow of the network and it also seems to
be behaving like a single firm consisting of suppliers, warehouses and retail stores.
For further improvement, they started using RFID technology in their distribution channel
where the product scanning is based on the numerical codes. They also encourage their
suppliers to use this technology in replacement of the bar code scanning. This not only help
the company in saving operational cost but the cost relation to the labour aspect also goes
down with the rise in productivity as employees efforts are used at other places of the
operations.
The other aspect of their supply chain includes their strong and efficient logistics
infrastructure system. More than 5,600 trucks and 6,900 drivers in 48 states serve Wal-Mart
distribution centres. In addition to this, their private fleet also offers the delivery with
efficient transportation services to the stores. In the current phase, the Wal-Mart private fleet
transportation operates in 28 states with around 36 transportation offices (Holmes, 2011). In
addition to this, Walmart inventory management is also one of the biggest contributors to the
success and growth of the company. The company is known for its cutting-edge applications
in the technological environment, which also help them in optimizing the performance of the
inventory management. Walmart manage their inventory effectively by implementing
vendor-managed inventory model which allows suppliers to access data from the information
system of Walmart such as level of inventories, the rate of goods sold to the consumer etc.
(Olson and Xie, 2009). which helps the suppliers to gather the information and decide when
to release the stock level to send additional goods to Wal-Mart.
Upstream Element
In a
supply chain, both primary and secondary distributions are included, which add value in the
form of customer satisfaction. Primary distribution is for accumulation a value for the
merchandise by an inbound flow into warehouse production plant or a distribution centre. In
both hierarchies of the supply chain, the retailer presence has been increased. This enables

them to practice their own logistics assests, which are generally involved in suppliers’ tasks.
In addition, they have to carry out the operations of logistics at the doors of manufacturers,
which has led to the Factory Gate Pricing (FGP). This defines that the transportation costs are
not counted by the provider in the price of the commodity (Morgan and Dewhurst, 2008).
For upstream operations, the evaluation is based on the cost and productivity performance
whereas for downstream operations, the measurement of flexibility and delivery need to be
steer based on the speed, design and flexibility (Fung, Chen and Yip, 2007).
RFID technology can also be used in the monitoring of the stock turnover so that the food
products are transported to the stores and this enables a continuous flow of goods in respect
with the demand of customers.
The upstream suppliers in Walmart are also align with the purchasing managers who are
accountable for selecting right suppliers and check whether performance is meet with set
standards or not. In addition to this, the planning, forecasting and scheduling of the flows of
material between the suppliers is managed by the material manager. All these managers are
accountable for the driving enhancement in the supply chain.
Wal-Mart also implemented the technological advancements into their supply chain so that
the performance and efficiency can be increased with the decrease in the various costs. They
have replaced barcode scanning technology with the RFID scanning (Zhu, Mukhopadhyay
and Kurata, 2012). This helps them in improving the various operations related to
procurement and inbound logistics in the supply chain of the organization.
RFID Technology in Upstream Element

Radio Frequency Identification (RFID) is an emerging technology, which helps many
organizations in solving problems relating to inventory management, timely deliveries,
tracking shipments and thus making the process much faster with more efficiency and fewer
errors. RFID combines with the EPC (Electronic Product Code) that can address the pain
points and gives a complete range of advantages across several segments like production,
retail, distribution and logistics (Bottani and Rizzi, 2008).
RDIF technology can be very helpful in the organic food products, which includes items like
meat, bread and milk. Wal-Mart can regulate their demand in the market by tracking of the
real time data and information of these organic foods and thus enables effective satisfaction
of the demand market.
With the help of this technology, the trading partners in the supply chain collaborate more
efficiently and achieve a new level of responsiveness and effectiveness. In a dynamic and real
time supply chain, the lines between planning and execution continue to blur.
RFID tags help the management and the other parties to get the information related to the
product like where it is, where is has been and much more information. This technology can
produce mountains of data related to the location of cases, pallets and individual product in
the supply chain (Attaran, 2007). It also gives the respective data relating to when and where
the merchandise is manufactured, picked, packed and shipped.
Another major advantage for Wal-Mart of using RFID in the supply chain is the automatic
reading of tags with the help of electronic readers. This saves a lot of labour cost, time and
efforts, which is used during the barcode scanning.
RFID also helps in reducing Bullwhip effect, which arises as orders are placed from retailers
to wholesales, to producers, with the increased variations increase at each step in the
arrangement (Dai and Tseng, 2012). This decreases the costs associated with inventory,
transportation and shipping.
In referring to the different parties in the supply chain, RFID help them in synchronizing
information and physical movement of goods across the supply chain from manufacturers to
retail outlets at the right place and right time. In addition, it can also check and track returns

goods in the supply chain and thus avoid counterfeit. This assists the management of
Walmart to reduce out-of-stock items.
Downstream Element
In this channel, the function of the products passes to the end consumer. Downstream supply
chain management is related to control the stream of goods and information with the
customer and clients. The wholesalers and retailers carry out major activities of the
downstream channel, as they are responsible for the delivery of goods to the end customer
(Carter and Easton, 2011).
Wal-Mart is more of a push system as the work release is based on the downstream demand
predictions where the pull system focuses actually more than the customer demand. It uses
pull system in upstream supply chain as Wal-Mart as a retailer tells the manufacturer what to
produce and how to produce?. In this down-stream channel, the secondary distribution
channel is followed.

Wal-Mart plans their downstream activities in a very effective manner so that one can be
benefitted and get the best value at the retail level. In addition, Wal-Mart also focuses mainly
on the demand planning and forecasting with the help of its every retailer, wholesaler and
demand markets (Wang, Liu and Wang, 2008). Outbound logistics are also a key activity in
the supply chain to add value to the customer by fulfilling their needs on time. Another
significant part of downstream supply chain includes the inventory planning, which is based
on effectiveness of all the partners in the downstream supply chain, i.e. distributor,
wholesales and retailer.
As a leading organization in the world, Wal-Mart ensures that their distributors have
maintained adequate levels of inventory so that to full-fill the needs of the demand market on
time. They also focus on other channel member’s activities in the downstream supply chain,
which includes logistics, transportation, marketing and sales. This all controlled and managed
through their internal information system connected by several intranets and extranets. With
the help of this, the organization successfully integrates the vertical and horizontal activities
of the supply chain.

Cloud computing is the use of various services including software, servers and storage on the
integrated network of internet, often referred to as “cloud” (Armbrust et al, 2010). In
networking term, Cloud computing did not build computing infrastructure as its uses
resources as a utility. It is based on large scale computing, where the facilities are deliver to
the individual or customer on the application and fast speed internet also plays a significant
role. .
On a global scale, various business including service organizations realized the potential of
cloud-based solution which can help them in to their supply chain strategies so that to
increase the proficiency and printability. Integrating cloud computing with supply chain also
gives an organization a competitive advantage in the industry which is necessary for the
growth of the business.
Considering Wal-Mart, installing cloud-based sensors can help in the safety of food products
and these sensors can help in producing information on location, monitor status and other
parameters that can help Wal-Mart to track their product items at every stage of the supply
chain. This enable them to isolate the specific time and place of any inconsistency. There are
various other advantages also for Wal-Mart of using cloud computing as a technology in their
downstream supply chain. The agility of the data compilation and sharing is an important
aspect in the supply chain (Swafford, Ghosh and Murthy, 2008). In case of Wal-Mart, the
company requires a supplier audit that was completed in Canada and the results are needed in
Australia about a demand of certain product. Therefore, within an hour, the decision needs to
be made in the alignment of supplier’s collaboration. With the help of cloud computing, the
management of Wal-Mart can easily compile the data and share this with HQ in the blink of
an eye. In the integrated computing, Wal-Mart can easily source the data from one cloud to
other, which gives their distributors a wide range of capabilities. In addition, Wal-Mart can
manage real time inventory that ensures that any of their distributors never losing tracks on
their inventory levels. In Wal-Mart, all their integrated individuals i.e. vendors, retailers and

SUPPLY CHAIN 12
suppliers can operate in a shared cloud where accessibility is more scalable. For a
multinational company like Wal-Mart, the parallel lines of communication and collaboration
in a real-time are necessary for their survival (Gunasekaran, Lai and Cheng, 2008). This
technology will give Wal-Mart a transparency solution in their supply chain that leads to
competitive advantage in the retail industry. It will also help the company to movie digitally
and serve their customers on a priority basis.

Recommendations
Wal-Mart is a leading organization, which has many areas to grow and increase their market
share. Wal-Mart should immune itself against the economic mishaps, manage risk factors
appropriately, use updated and advanced technology, rationalize or cut their cost relating to
supply chain and production and thus promote their market and brand into international
developing market. In addition, there are various effective measures, which can ensure long-
term sustainability of the firm and promotes efficiency in the whole value chain.
In the upstream element of their supply chain, implementing the practices of Radio
Frequency Identification (RFID) can bring the effectiveness and efficiencies that help in
resolving the supply chain issues like inventory management (Domdouzis, Kumar and
Anumba, 2007). This technology can help Wal-Mart to seize the correct data on the site and
position of physical objects throughout the supply chain.
RFID enable products leads the various food firms and other stakeholders of the supply chain
to verify the authenticity and safety of products inside a package as each tag has a unique ID
for the information tracking. In addition, this technology mechanism makes incorporation
easy for food, beverages and packaging companies.
Wal-Mart should not only use RFID in simply replacement of the barcodes, rather than they
can use them by equipping cargoes with the tags viewing the content so that the customs
clearance can be made in an automatic way. This will help Wal-Mart in creating a borderless
supply chain (Shi, Tao and Voß, 2011).
They can also share the information with the suppliers and developing alliances and thus
achieve strategic objective of lowering the cost at various places.
Therefore, this technology enables Wal-Mart to significantly change their business processes,
supply chain management, and connect the true corporate value of the technology by driving
innovation and profits.
The other technology is the cloud computing which can be used to create more efficiencies in
the downstream section of the supply chain. The main benefits to the Wal-Mart in
implementing cloud computing in their downstream portion of the supply chain will lead to
cost efficiency, flexibility, simplifications and sustainability.

SUPPLY CHAIN 14
Considering Wal-Mart, from demand forecasting to warehouse or transportation planning,
there are multiple applications, which can help the supply chain to link with the single-cloud
based platform. This can help the partners in the supply chain have contact to such platforms
on their personal environment or corporation regardless of their place and this can all be
possible through a common device. This process can enable Wal-Mart to be more agile and
lead them to quickly enter new markets with the new commodities and services.
In addition, the Cloud-based system can help management in providing real-time visibility of
inventory and shipments and thus enhance tracking in logistics segments. (Marston et al,
2011). In Wal-Mart, implementation of these systems can be treated as a virtual warehouse
for their products in their pipeline and offer the company to make strategic order full-
fulfillment decisions. Cloud based ERP system can ensure comprehensive food safety
management capabilities that can help the company to easily produce traceability records
instantly in a single solution as the supply chain in this global economy is more complex and
extensive.
For managing the upstream and downstream element of the supply chain efficiently, Wal-
Mart can adopt various other technologies also which will enhance the overall productivity.
These technologies include IoT, ERP, Drones and Immersive technologies including VR
(Virtual Reality) and Artificial Reality (AR) so that to enhance employee and customer
digital experience. For example, for improving warehouse efficiencies, Wal-Mart can use the
VR technologies with the help of scene recognition during the order picking process. Vision
Picking helps the company by enabling hands free order picking at a faster pace and fewer
errors. In addition, Wal-Mart can also use ERP software applications which improves
efficiency in handling procurement and supply of goods across the supply chain. From
manufacturing and warehouse resources to the transportation and finishing process, these
applications of ERP offers cross-platform visibility on all the elements of the supply chain.
In managing the supply chain, the field of cloud computing can seem as relatively new but it
is rapidly increasing over time and thus implementing them in a timely manner can give the
company a competitive advantage.
