INTRODUCTION
Information technology refer to the use of computer as well as software in order to create,
process, store, exchange, secure as well as retrieve the data based on the purpose of operations
(Rajaraman, 2018). Many companies have their own IT departments from where they can
manage all the storage of data and works on the technical data to retrieve the valuable
information that helps in decision making process. To better understand the report Tesco
company has been selected which is one of the leading multinational retail stores of UK. It has
huge customer base as the company deals in various goods like clothing, furniture, grocery and
electronics under one roof this provide huge convince to the customer. This report cover
following topic such as role of IT in the success or failure of Tesco. Analyse the ethical and
social issue to run the business as well as difference between different type of networking
technology. Further, importance of intranet and internet are covered in this report.
TASK 1
Identify the role of IT in the success or failure of Tesco
The information technology department is responsible to manage the electronic
technology of business like centralised database, business computer network, information
security, and business software deployment (Rivard and Aubert, 2015). Thus, a successful
business is a combination of business as well as technical skill that helps the business to
formulate effective decision and adopt the changes successfully.
According to Andrea Lee, (2016) Tesco which is multinational company and run its
business in both developed and developing country so in order to succeed it uses the information
technology to its advantage. Additionally, investing or strengthening information system has
helped the company to generate strong profit and enhance their profitability. Initially, Tesco used
to sell the grocery from the stalls in UK but later on with the use of essential information system
assisted the company manage as well as run all the department of business by maintaining the
coordination among them. These IT system helped in bringing the transparency as it helped to
identify for how many hours employee work and how much output do they produce within
stipulated time period. Along with that it helps in understanding the customer by maintaining the
database through electronic devices. Like, respected company maintained the membership card

database through electronic devices. Like, respected company maintained the membership card
as well as loyalty card that helped to define the purchasing power of customer as well as help in

formulating strategy in order to compel the customer to purchase the daily utility or shopping
item from respective store. Therefore, some of the technology used by Tesco to gain long term
success are defined below:
RFIA Technology: For the convenience of employee in stock counter Tesco introduces
the well known technology named RFIA enabled barcode. This technology is used to
automatically count the stock of store and when it fall short it directly update the supplier. This
technology does not require any supervision as well as transmit the data by its own due to which
even customer do not find any shortage of inventory. Thus, it is a successful technology adopted
by company to manage their inventory effectively.
IFTTT(If This Then Than): This technology was developed to enhance the online as
well as offline shopping experience of an individual. Further, company launched the application
which display all of its product (Technology in Tesco. 2016). Along with that it also helps to
intimate whether the price of any product goes up or down. Hence, it play a successful role to act
as a stimulus that instigate the customer to take quick and fair decision.
Advanced E-commerce: With the trend of internet and increase in digitalisation, Tesco
took the initiative to generate the human traffic from online platform. Thus, company posted
multiple images, content as well as video to appeal the interest of consumer (Bawden and
Robinson, 2015). The company also introduced its own payment method that is PayQwid which
customer uses at the time of making online payment. This is a successful process that helped to
spread the awareness about the company.
BYOD Integration: BYOD stands for Bring Your Own Devices, this information
technology is basically an application which is used by store managers to download and login
record of real time stock. The information is transmitted while scanning the product sue to which
it record the accurate information in relation to inventory. Moreover, the other advantage
associated with this technology is that internal staff can instantly and effectively deal with the
customer due to which is time effective technology.
Therefore, Tesco not only maintain its existing innovation but also adopt the new
technology to gain the privileged of fastest growth and put the best possible effort to achieves the
long term sustainable growth and development.

TASK 2
Ethical and social issues to run the business effectively
Tesco is effectively using the technology to manage the inventory, customer base and
information related to product. For instance, company developed the clubcard that helps in
collecting the points and provide discount to the ultimate consumer (Marzetta, 2015). Further,
with the help of these card company collect all the vital details of their consumer such as name,
contain details, address, birthday and frequency of purchase. This helped in enhancing the sales
and marketing strategy of company. According to Bradley Mitchell, (2019) Although there are
several advantage associated with information technology but on the same way there are certain
ethical as well as social issues faced by the selected issue which are defined below:
Overload of data: As Tesco has huge market share as well as customer base which leads
to overload of data. It become critical situation for the professional of Information Technology to
identify the relevant data amongst irrelevant ones (Tesco Ethical issue, 2018). Therefore, in order
to handle enormous amount of data require sophisticated software, processing power as well as
human analytical skill. Therefore, it is a social issue faced by company that can affect the
decision making process of business.
Security issues: Security breach is the major concern for the big MNCs like Tesco as
electronic storage of data is one of the biggest assets of company from which effectively future
decision can be made based on the changing requirement or need of customer. Thus, security or
social issue is the primary concern for company that can damage the profitability as well as
goodwill of company.
RFIA Technology: RFIA refer to Radio Frequency Identification which is used to detect
the inventory. This was developed for the convenience of customer as well as to maintain
goodwill of respective store. But there are certain ethical issue related to the same like it track the
buying behaviour of customer so if customer purchases any product from the store then there
picture are captured by this technology and again during the time of checking out of customer the
other camera captures the picture. The purpose of doing so is for the security staff purpose that it
do not lead to theft. Therefore, this spy practice and capturing the pictures of customer can be
beneficial for the company but ethical issue for customer (Lloyd, 2017).
Discrimination: It come under the ethical issue which can be faced by the employees of
an organisation. Initially, Tesco was involved in the discrimination activity based on the

Discrimination: It come under the ethical issue which can be faced by the employees of
an organisation. Initially, Tesco was involved in the discrimination activity based on the

remuneration provided to the male and female employee on the similar task. Due to which
company faced the protest of employee that affect the goodwill of company. Later on to run the
business effectively Tesco changed all its policies and come up with uniform policy for all the
internal member. Hence, it helped the company to overcome the crises and re-establish their
image in the public.
Therefore, there are several ethical as well as social issue which can be faced by the
company so they need to identify these issue and work on the technical field so that no external
party can access the data of the company.
TASK 3
Identify and difference between various type of networking technology
According to Dinesh Thakur, (2018) Computer network refer to the group of computer
which are linked with each other in order to share data and resources. It simply allow various
computer to connect as well as communicate. There are basically three types of network which
are defined below:
Local Area Network (LAN): LAN is one of the widely used network that is used to
connect those devices which are at the short range or distances which are in proximity. Here,
information is shared or transmitted within the proximity. Herein, Tesco can use LAN
networking technology to connect the people working in the same store. Further, one of the
computer is server while other which are connected to it is client. This help them to access high
speed of internet in order to provide speedy services. Additionally, it helps to share the file or
information amongst the interconnected network.
Metropolitan Area Network (MAN): The ownership to handle the MAN stays in the
hand of single authority or council. It simply connect the various LAN through single cable and
span in the entire region or city (Computer Network. 2018). Herein, respected company can use
MAN as it has high speed and one of the fast mode of communication. It also helps to transmit
the data in both direction.
Wide Area Network (WAN): It is used to cover long physical distances and has high
network connectivity to cover and communicate with one who is miles apart. In relation to
Tesco, can use WAN as it has over six thousand stores and it is necessary for the organisation to
maintain the connectivity amongst various stores which are far apart from each other.

Therefore, amongst the various networking technology Tesco adopts Wide Area Network
that is WAN as is transmit the data, share resources and software at the long distance. All the
message whether it is inform of data, sound and picture can be easily attached and share (Xiang,
Magnini and Fesenmaier, 2015). Hence, it helps to keep the coordination amongst the business
function of various store.
