also explained the opportunities for the financial services to apply innovative data sets as well as
algorithms to the business operations which will optimize resources allocations, management of
cash and processing of currency. Chen et al. (2015) defined the big data as the tem used to
describe as vast growth as well as data availability, structured in addition to unstructured.
According to Choi, Chan and Yue (2017), the financial business organizations are
struggled to the profit from huge amounts of data as well as banks only use of the portion of the
data for generating insights that enhance the experiences of the customers. Demirkan and Delen
(2013) found that the banking sector is applied of big data leads to 4% increase in the market
share over the banking operations. According to Galbraith (2014), the big data analytics is a
required part of the commerce strategy which helps to detect as well as prevent the financial
crime. The big data enabled the banks to implement of real time big data analytics on the large
scale for meeting with growing financial threats. George, Haas and Pentland (2014) stated that

Wu et al. (2014) stated that one significant feature of big data is that the use of big data
can help in representation of diverse dimensionalities of the stored data. The use of big data
enables the different information collectors to collect the much needed information about a
chosen problem. The autonomous data sources related to application of decentralized and
distributed control is considered to be other significant characteristics of big data applications. In
big data analytics, each source of data is able to generate data without making use of any
centralized control. In this context, the several uses of big data in banking sectors can be
evaluated.
Use of Big Data
From perspective of increasing business profit, big data is mainly used for employing
better considerate of the preferences and the behaviours of the related customers of a particular
organization. The banking sector make use big data in analysing the customers’ behaviours and
their preferences. The use and adoption of big data in various business sectors has considerably
increased mainly because it helps in increasing the efficiency of a business organization and
further help in better decision making. Since big data consists of both structured furthermore
unstructured data, an efficient mining of big data is necessary.
Apart from increasing the competitive advantage, the use of big data can prove to be a
cost saving approach for collection and analysis of hidden data patterns and research data.
According to George, Haas and Pentland (2014), there is an increasing use and emphasis on big
data and business analytics in the banking sector as it has an ability of capturing the value for
individuals and business communities. Big data is gradually becoming a tool for not only

6. Customer Segmentation: With the use of big data, many marketing programs can be
conducted. Identification of the usage of cards by the customers, there is need to create a loyalty
program. By integrating the big data in a bank, a relationship can be established with the
valuable customers (Shin 2016). Big data gives the banks to know their customer very well
knowing their spending habits as well as patterns, simplify the tasks that ascertain the needs of
the customer and what the customer wants. With the big data implementation, the banks can
track the transaction of all the customers and can also categorize the clients that are based on the
parameters such as accessed service, expenditures on their credit cards, and even the net worth
(Sivarajah et al. 2017). The advantage that the big data includes in customer segmentation allows
the banks to have better target on the clients related to the marketing campaigns that cater their
requirements.
7. Feedback from the customer: The sentiment of the customers can be gathered in terms
of feedbacks that are available on different websites of social media. Once the feedbacks are
collected, they are needed to be classified in two categories including the positive feedbacks and
the negative feedbacks. Different filters can be applied that helps to provide a better service to
the customers.
2.5 Root cause of customer dissatisfaction and Use of Big Data
The pace with which the data initiatives are taken in the banking industry is mainly

(Warren et al. 2015). Incorrect identification of customers’ need and delay in the resolving of the
queries of the customers can be one of the most significant reasons behind customer
dissatisfaction. Big data can be a solution to this problem that deals with the identification of
issues that can contribute to customers’ dissatisfaction. There are a number of factors that can
contribute to the causes of low customer satisfaction. Lack of effort of the company service
personnel in understanding and resolving the customers need can result in increase of the
customer dissatisfaction towards a particular organization (Hofacker, Malthouse and Sultan
2016). Another significant reason for customer dissatisfaction is failing to focus on the
experiences of the customer. This is one of the most prominent risks related to customer
satisfaction (Gu and Ye 2014). It is quite necessary to understand the major reasons behind
increase in customers’ dissatisfaction in order to analyse the process by which the use of big data
in banking can help in addressing the problems related to customers’ dissatisfaction.
As evaluated in the previous sections, the use of big data can significantly help in solving
a majority of business problem that is associated with the collection and analysis of data. From a
large volume of structured and unstructured data, it is possible to understand the main reasons
behind customer dissatisfaction (Özköse, Arı and Gencer 2015). The mining of large volume of
unstructured data obtained from various sources can considerably help in identification of the
factors behind customers’ dissatisfaction, which in turn can help in better analysis and
elimination of the problems. There are a number of processes that can help in accessing the
factors related to customer’s dissatisfaction. These factors are needed to be identified so that a
solution to the problem can be suggested. The loss of customers due to increasing dissatisfaction
is an issue in the banking sector and therefore, it becomes quite integral to eliminate the issues.

One most significant process is to make use of big data to mine the factors contributing to
customers’ dissatisfaction.
According to Piha and Avlonitis (2015), customer defection in retail banking can be
associated with the behavioural influences of a unsuccessful service superiority (Power 2014).
The root cause of customer dissatisfaction or customer departure can be related to the services
and the quality of services that is offered to the customers (Phillips-Wren and Hoskisson 2015).
The authors conclude that one of the major reasons behind the customer dissatisfaction include
demonstration of the effects of failed service quality and the negative approachs of the retail
bank provider (Phillips-Wren and Hoskisson 2015). The negative impact on the failed service
quality affects the loyalty of the customer and therefore, it becomes one of the root causes of
customers’ dissatisfaction.
The dis-satisfied customers can considerably affect the revenue of a financial institution
and therefore, identification of risk mitigation approach of the same is needed to be identified.
Sunder (2016), states that process improvement is considered as important aspect of
organizational development. This is same for financial institution as well. It is quite essential for
the banking industry to identify and analyse the root cause of customer dissatisfaction. It has
been observed that big data can be a solution to the problem (Fang, Jiang and Song 2016).
Mining of a large data set of unstructured data can help in identification of root cause of
customers’ dissatisfaction. The employ of big data analytics can significantly help in measuring
the data process and performance of a project (Phillips-Wren and Hoskisson 2015). Each and
every bank maintains a huge database of customers’ information that stores every confidential
detail of those customers. Mining of those details can considerably help in understanding the
customers’ needs, preferences and the reasons behind their dissatisfaction.

Since data mining can considerably help in better identification of the causes of
customers’ dissatisfaction or the factors that can considerably affect the retention of the
customers of a financial institution (Rehman et al. 2016). The use of big data can not only help in
identification of the causes of customers’ dissatisfaction but also can help in identification of the
factors that can help in managing the customers’ dissatisfaction. Mahapatra (2014), argues that
identification of the factors that contributes to customers’ dissatisfaction is quite challenging. A
number of investigators have been performed earlier in order to determine the processes that can
help in identification of the root cause of customers’ dissatisfaction in banking sector. Mahapatra
(2014), further identifies that it is possible to identify the real causes of the enduring
dissatisfaction of the customers. The critical step associated with the consideration and execution
of consumer dissatisfaction is related to mapping the factors behind the response of each
customer towards perceived dissatisfaction. The research study undertaken by Mahapatra (2014),
indicates that intensity of customers dissatisfaction is directly associated to number of times, a

2.6 Pitfalls of Big Data in Banking Sector
The disadvantages of big data that are included in the banking sector are stated below:
1. Difficult to control the siloed data: The data in the banking sectors are wide and
diverse and are integrated in different places or departments. It is not possible to profile a
particular customer based only in terms of the investment behaviour such as the account, the
loans taken by the customers or similar instances (Corbae and D'Erasmo 2019). The data may
spread over large branches and can be spend on different departments of banks. The big data
needs to accumulate all such data in a particular space and provide intelligence accordingly
2. Upgrade the Legacy infrastructure: Most of the solutions in banking sector are always
not equipped for handling the constant data influx even if the data are moved to the cloud
solutions. Handling of constant data is a pre-requisite of big data solution. Implementation of big
data mainly requires complete revamp to the existing solutions of bank along with a big data
company. All the legacy infrastructure of the bank should be upgraded before integrating the
capabilities of big data. Big data is not very easy to implement as all the systems needs to be
changed constantly that are deployed.
3. Correct Implementation of dedicated resource with big data company: The banks
usually do not have expert who can handle big data as well as can analyze the partnerships with
the firms that specializes to design, deploy as well as develop the solution of big data. The
implementation of the software should be done correctly with correct choice of correct company.
4. Big Data is not Strategic Asset: The managers of a bank and the executives at the top
level often neglect the need to depend on the big data more compared to the human decisions.

Identification of appropriate methods of data collection is important for conducting the
analysis of data and interpretation of those data (Brinkmann 2014). Depending on the collection
methods of data, there are mainly two types of data methods – primary and secondary. The
primary data is basically the raw data which is responsible for providing detailed insight
information based on the research topic which is selected. On the other hand, secondary data are
those which are mainly gathered by other groups of people.
In this study particularly, primary method of data collection is used for providing help in
identifying the impact of big data analysis on the banking sectors (Smith 2015). The data is
collected from the use of surveys as well as online questionnaire. A collection of questions is

prepared based on the research topic which is selected. For collecting information, the researcher
evaluated all the feedbacks from several respondents and all the questions are considered for
extracting sensitive information related to the effect of big data analysis on the banking sectors.
3.5.2 Data analysis methods
In this study particularly, the researcher has made use of both quantitative and qualitative
analysis of data for arriving at the findings of research. It is recognized that there are limitations
of one method of research which is seen to be compensated by the strength of other methods
(Silverman 2016). There is a combination of both qualitative and quantitative method which is
seen to be very good for a mixed design for getting findings which are reliable (Panneerselvam
2014). The researcher has opted to obtain qualitative data from the employees of the banking
sectors though the use of survey questionnaire method. This data analysis method is utilized for
triangulating the primary research for involving the evidences to the literature study. There is the
35EFFECT OF BIG DATA IN BANKING SECTOR
combination of both deductive and inductive method of the research. Quantitative is obtained
from the questionnaire in the form of both charts and graphs.
This particular study comprises of mixed data analysis which is used where the
researcher has taken the employees from various banking sectors and takes all of their responses
with the help of online survey, questionnaire and telephonic interview. This method of data
analysis can be resulted into the evaluation of the employee engagement for providing their
feedback on the effects of big data analysis in the banking sectors. This method has allowed the
researcher in getting the numerical data which is interpreted for displaying it in the graphical
format which further displays all the triangulations.
3.6 Population and sample
In this particular research study, the population is considered to be the number of people
who are involved both directly and indirectly into the processes of research (Taylor, Bogdan and
DeVault 2015). The sample employees of the banking sectors are taken where the survey is
being performed based on 1 = Strongly Disagree, 2= Disagree, 3=Neutral, 4=Agreed and
5=Strongly Agreed. For conducting the quantitative research techniques about 100 employees
are interacted and considered by taking the help of online questionnaire forms. Hence, the
sample size of the study is 100. For conducting the qualitative data analysis, 5 employees are
taken randomly from the participants.
3.7 Ethical considerations
Conduction of the ethical research is par with the rights of human acted which is specific
to the right to esteem for the correspondence. All the respondents which have provided their
responses based on the survey questionnaire have also been provided options for revealing and
combination of both deductive and inductive method of the research. Quantitative is obtained
