Abstract
Smartphone’s have become increasingly popular for personal and work use.This research
investigates Smartphone usage at workplace, whether it is of assistance or interference to
work and its implications on performance of employees. This survey method consists of a
sample of 576 IT Professionals. It was observed thatknowledge sharing and flexibility has
more influence on the assistance to work variables on the job performance of the
employees. Moreover Non-work purposes and Job Stress has more influence among the
interference to work variables on the job performance of the employees.
1. Introduction
In the country of 1.3 Billion people, mobile phone subscriptions in India have already
reached 1 Billion, according to the latest data by TRAI. The low cost of mobile data and free
accessibility to the internet via Wi-Fi in many areas, is fascinating Smartphone users like
never before. In addition, expansion of 3G and 4G network coverage is further expected to
boost Smartphone sales in the country. According to an analysis, the Smartphone shipment
has grown at a CAGR of around 76% during the period 2010-2015. (ASSOCHAM, 2016)
Hence this study aims to explore Smartphone usage at workplace, whether it is of assistance
or interference to work and its impact on the job performance of IT professionals in Chennai,

with a view to suggest measures to the Software Organisation for attaining balance in Work
life realms and improved productivity.Studies concerning impact of Smartphone on
Assistance to work and Interference to work have predominantly taken few factors only in
previous studies. Smartphone Usage Intensity has not been studied much in India in IT
Companies. This is the first study of its kind to combine the impact of Assistance to work,
Interference to work, Smartphone Usage Intensity, Job Performance and Productivity.
2. Literature Review
According to the International Telecommunications Union (ITU), a United Nations agency
that conducts statistical data on Information Communications Technology (ICT), mobile
device usage has grown at an amazingly fast rate in the past 10 years. With this has come a
giant leap forward in the proliferation of Smartphone and their use to access the internet. As
current mobile trends develop, it has become apparent that mobile Smartphone cannot be
ignored in marketing research initiatives any longer, Fluid Surveys (2013). Reasons for this
are primarily that it allows for many communication possibilities, all in the same device,
Murad Moqbel, (2012), Jacob Grauers, (2012). Furthermore, the Smartphone usage is
constantly increasing, both seen to numbers of users and data traffic generated (Cisco, 2012).
Assistance to Work
Technology advances made it so that people no longer have to wait to be at a computer, or at
the office, to accomplish their work. This should allow for maximum flexibility for
employees to work wherever is convenient for them, Tricia R. Harris (2014).Chu and Chan
(2009) suggest that in today‘s rapidly changing business environment innovative
organizations could use online communities to identify and capture new ideas for creating
new products and services.
Knowledge sharing is an activity through which knowledge (namely, information,
skills, or expertise) is exchanged among people, friends, families, communities, or
organizations. For IT professionals, whose performance depends a lot on the acquisitionof
technical and organizational knowledge, their social networks are an indispensable informing
channel, Burton, Wu, & Prybutok(2010). A Research on Mobile Learning at Workplace by
(Towards Maturity, 2014) found that those with several years‘ experience in
usingtechnology-enabled learning report higher levels ofmobile usage, but we also see a

spike in usage in thosethat are new to using learning technologies, implyingthat some are
adopting mobile solutions as part of theirfirst steps with learning technologies.
Communication is a process in which participants create and share information with
one another in order to reach a mutual understanding, Carol Xiaojuan Ou Choon Ling Sia
Chun Kit Hui, (2013).The technological advances and increased use of the Internet in recent
years have ledto a communication revolution, (Moqbel, 2012). This communication
revolution, as well asthe more technologically empowered lifestyle of individual users, has
changed the waypeople communicate and connect with each other (Coyle, 2008; O‘Murchu
et al., 2004).
Smartphone enables employees to Organise their work/ manage their work; it gives more
opportunity to be creative and efficient in scheduling of work and meetings. Smartphone also
gives an opportunity to individualise work and provide physical freedom of movement in
work.Smartphone technology also enables users to collaborate digitally with peers, co-
constructing knowledge, Mcgreen & Sanchez, (2005) digitally (via wikis, web forums, blogs
etc) and sharing it (via email, social networking sites like Facebook/LinkedIn and virtual
folders suchas Dropbox), Tonta (2008). Younger employees and those with a millennial
mindset find it hard to draw the line between their personal and professional lives and seek
the flexibility and ease-of-use that their personal devices provide (Cognizant. 2012).
Flexibility in the workplace allows employers and employees to make arrangements about
working conditions that suit them. This helps employees maintain a work/life balance and can
help employers improve the productivity and efficiency of their business. Job flexibility in
this study centres on the location and the timing flexibility of work(ubiquitous
access),Haejung Yun, et al,(2012). These evolving technologies also have an impact on the
way of working. The telecommunication tools made it possible to do the job that was
formerly done in the office, outside the office.
Interference to Work`
Interference to job tasks included drawbacks such as receiving information from Social
Networks which cannot be handle by individuals while at work, receiving information that
are not useful for work and getting distracted from work,Vathsala Wickramasinghe and
M.S.M.Nisaf, (2013). Heavy Smartphone and computer usage is causing stress, insomnia and
depression physical symptoms reported in relation to mobile phone useinclude headaches,

earache, and warmth sensation but alsoperceived concentration difficulties and
fatigue,Thomée, (2012).
Work overload the situation in which someone has too much work to do. The dual
use (work and nonwork use) of smartphone environments has resulted in a merger of work
and personal life. This can cause a situation in which employees perceive greater work
overload than before using their smartphones for work purposes,Haejung Yun, William J.
Kettinger, and Choong C. Lee,(2012).
The deviant use of Internet technology may distract employees to engage in non work
purposes, from job tasks on hand and may engage in unproductive or unethical activities such
as online shopping, news, music, chatting, auctioning and games while at work,Vathsala
Wickramasinghe and M.S.M.Nisaf, (2013).
According to Thomée (2012), Stress caused by the increased usage of information and
communication technology (in our case, particularly with regards Smartphone) can come in
different forms. The boundlessness that a Smartphone creates means that it is easy to perform
work related tasks in one‘s leisure time and to do leisure time activities at work. Just this
basic effect of Smartphone usage can cause role stress, role conflicts and role overload.
Smartphone usage distracts employees from information at meetings, and also annoys
others (Ebelhar, 2009). Chen et al, (2008) suggest that the deviant use of Internet technology
may distract employees from job tasks on hand and may engage in unproductive or unethical
activities such as online shopping, news, music, chatting, auctioning, and games while at
work.
The term behavioural addiction correctly refers to a compulsion to engage in a natural
reward, which is a behaviour that is inherently rewarding (i.e., desirable or appealing),
despite adverse consequences, Malenka RCet al, (2009), Robison AJ, (2011). Media use has
become so much a part of young adults‘ lives that many do not realize their level of
dependence and/or addiction to their cell phones, James.A.Roberts et al,(2014).In this regard,
Chen et al, (2008) and Stanton, (2002) provide evidence that internet addiction significantly
impacts employees‘ internet abuse at the workplace. For instance, Irfan Ahmed Mohammed
Saleem, Dr. S. Jaisankar (2018), employees‘ Online Social Networking addiction may result
in a decline in employees productivity (Ferreira and du Plessis, 2009; Lichtash, 2004; van
Zyl, 2009)

3. Research Methodology
The research problem clearly states thatthe aim of the study is to explore the influence of
Smartphone Usage Intensity on Assistance to Work, Interference to Work,Job Performance
and Productivity of IT professionals. This becomes important because the popularity of
Smartphone is relatively new, and employees engaging in Smartphone during office work
hours are growing while scholarly research in this area is presently lacking. Hence this is an
exploratory research. Both Indian and International studies were taken into consideration.
From the previous studies the independent and dependant variables were listed. This survey
method consists of a simple random sample of 576 IT Professionals based in Chennai.
Questionnaires were distributed to 800 employees and 605 were returned out of which 576
completed questionnaires were received. . A questionnaire was adapted from previous studies
suitable for the present study. The questions were referered from previous work of
researchers and were revised for easy understanding of the employees. The questions on
Smartphone usage were rated on a five point Likert scale, having 1 = very low, 2 = low, 3 =
neither high nor low, 4 = high, 5 = very high and the other questions were rated on a five
point Likert scale, having 1=Strongly Disagree, 2= Disagree, 3= neither Agree nor Disagree,
4= Agree, 5 = Strongly Agree.
Research Objectives
To study the influence of Smartphone Usage and Assistance to work on Job Performance.
To study the influence of Smartphone Usage and Interference to work on
JobPerformance.
4. Data Analysis Procedures
Every hypothesis is tested to check for statistical significance. The statistical techniques are
applied using the Statistical Package for Social Sciences (SPSS) computer program for
Windows version 20.0. T-Test, Correlation and SmartPls were used to test the hypothesis and
model of the study.
The construct assistance to work has four variables namely knowledge sharing,
communication, organising work and flexibility. Existence of difference in the perception of

respondents with respect to the four variables was tested across the High and Low
Smartphone Users. The hypothesis is as below.
Testing of Model Fit using SmartPLS
Partial Least Squares is a family of alternating least squares algorithms, or ‗‗prescriptions,‘‘
which extend principal component and canonical correlation analysis. The method was
designed by Wold (1975, 1982, 1985) for the analysis of high dimensional data in a low-
structure environment and has undergone various extensions and modifications. Partial Least
Squares- Path Modeling is a statistical approach for modelling complex multivariable
relationships among observed and latent variables. Structural Equation Models include a
number of statistical methodologies allowing the estimation of a causal theoretical network of
relationships linking latent complex concepts, each measured by means of a number of
observed indicators, Vincenzo Esposito Vinzi, (2010).
Model 1 – Assistance to Work
The hypothesized framework was constructed with Smartphone Usage Intensity as an
independent construct and Assistance to Work constructs as a mediating construct. Job
Performance and Productivity are the dependent variables. The model was tested for
goodness of fit and the results are as follow.

Fitness of the Structural Model
The t statistics in the table above indicate that all structural path coefficients are statistically
significant (>0.05) (Chin,1998, 2010, Henseler et al.,2009, Latan & Ghozali,2013). The
values well abide the prescribed limits thus ensuring that the structural model has a good fit.
From the table it can be inferred that knowledge sharing (4.85) followed by flexibility(1.64)
have a more influence among the assistance to work variables on the job performance and
productivity of the respondent. Moreover Communication and Flexibility increase as
Smartphone usage intensity increases.
Model 2 – Interference to Work
The hypothesized framework was constructed with Smartphone Usage Intensity as an
independent construct and Interference to Work constructs as a mediating construct. Job
Performance and Productivity are the dependent variables. The model was tested for
goodness of fit and the results are as follow.

Fitness of the Structural Model
The t statistics in the table above indicate that all structural path coefficients are statistically
significant (>0.05) (Chin,1998, 2010, Henseler et al.,2009, Latan & Ghozali,2013). The
values well abide the prescribed limits thus ensuring that the structural model has a good fit.
From the table it can be inferred that Non-work purposes (1.18) followed by Job Stress (1.13)
have more influence among the interference to work variables on the job performance and
productivity of the respondent. Moreover Work Overload (5.88) and Job Stress (5.26)
increase as Smartphone usage intensity increases.
5. Conclusion
Results have confirmed that there exists difference in perception of Communication and
Flexibility by the respondents of who have high and low Smartphone usage. Whereas for the
variables Knowledge Sharing and Organising Work there is a no difference in perception of
Knowledge Sharing and Organising Work by the high and low Smartphone users. Knowledge
sharing and flexibility have more influence among the assistance to work variables on the job
performance and productivity of the respondent. Moreover Communication and Flexibility
increases as Smartphone usage intensity increases
There exists difference in perception of Non work purposes, Job Stress and Addiction by the
respondents who have high and low Smartphone usage. Whereas for the variables Work
Overload and Distraction there is a no difference in perception of Work Overload and
Distraction by the high and low Smartphone users. Non-work purposes and Job Stress have
more influence among the interference to work variables on the job performance and

productivity of the respondent. Moreover Work Overload and Job Stress increases as
Smartphone usage intensity increases.
Smartphone introduces a multitude of challenges; however, organizations and employees
should treat thisas an opportunity that can yield significant benefits and improved
productivity. The key is to approach this in a holistic fashion to address employee
expectations,while ensuring business requirements are met related to non-work purposes, job
stress, flexibility and knowledge sharing.
