A World of Difference

3. From the
CEO’s Desk
for growth. We started a new talent paradigm in
the Kingdom of Saudi Arabia by creating the first
all-women center in BPS and IT.
I am proud that as an organization we sustain and
improve the quality of experience of our 1500+
customers. Over 96% of our customers appreciate
the responsiveness and accessibility of our project
teams; 98% consider TCS a partner of choice and
are willing to endorse our capabilities; and 94%
feel that it is easy to collaborate and do business
with us.
As an organization, we continue to build our
people strength through diversity in multiple
dimensions. While our total employee base
reached 319,656 this year, making us the
third-largest employer in the global IT services
industry, we were also delighted to celebrate the
landmark of employing 105,481 women – a rare
feat in the corporate world also in the context of
TCS being host to 122 nationalities across our
global footprint of 232 locations.
Dear Stakeholders,
I am glad to connect with you around this time
each year on the occasion of the publication of
Tata Consultancy Services’(TCS) Corporate
Sustainability Report. This is our 9th edition of
the Report since 2007.
I am pleased to reaffirm our support to the Ten
Principles of the United Nations Global Compact
in the areas of Human Rights, Labor, Environment,
and Anti-Corruption.
FY 2014-15 has been another year of industry
leading growth rates and deepening our footprint
in key markets. Our revenues grew 15.7% to $15.5
bn on a year-on-year basis and our net profits
grew 12.8% to $3.54 bn1
while sustaining our
operating and net margins.
We intensified our focus on markets such as Japan
– crafted a new joint venture with Mitsubishi Corp
to strengthen our presence and create a platform

4. While we focus on business, we also continue to
promote the health and wellness of our
employees through the Fit4Life program.
Sponsorship of marathons like the TCS New York
City Marathon has created a unique opportunity
to engage with communities in health and
wellness. With our Purpose4Life program, TCSers
volunteered over 200,000 hours globally to make
an impact in communities in education, health,
and environment.
These are exciting times when India has taken the
lead in mandating corporate spend on social
causes.
FY 2015 represents the first year for reporting on
CSR under the new regime of the Companies Act
2013. TCS has a CSR Committee of the Board and
has published a global CSR Policy. We have also
established a CSR Foundation to undertake
large-scale projects. This is in addition to the
existing volunteering and projects which utilize
core competency to support social causes.
TCS was among the first corporates to identify
with the Prime Minister's Swachh Bharat Abhiyan
(Clean India Initiative), and has pledged ₹100
crores to build dedicated sanitation facilities for
girl students in government schools. Our CSR
flagship, the Adult Literacy Program, reached over
2,00,000 beneficiaries, with around 30,000 jail
inmates becoming literate.
STEM education has become a focal point for our
community efforts in the USA, Canada, UK, and
Australia. Since its inception in 2009, goIT has
impacted more than 8,800 students across 11
cities. In UK, the IT Futures program has facilitated
learning for students in 160 schools. TCS is also
proud to be a founding donor of the Queen
Elizabeth Prize for Engineering.
The safety and well-being of our employees is of
prime importance. Our drive on road safety,
ergonomics, fire safety, general office, and
personal safety is strengthened with a behavioral
safety approach. We have deepened our
engagement with employees on safety, and
converted them to being safety responsive.
TCS promotes employee health and wellness

5. We have completed a year since the launch of the
Safety First initiative on May 2, 2014 in which we
had chosen to focus on Accidents, Crime, Health,
and Self Harm. We are constantly working to make
TCS a‘Zero Incidents’organization – both
internally and externally.
The endeavor to pursue our Environmental
Sustainability Roadmap continues. Carbon
footprint and energy management are among
areas of strong focus. We continue to work toward
the target of specific carbon footprint reduction in
order to decouple business growth from the
carbon and energy footprint. Green buildings,
green IT, operational energy efficiency, and
renewable energy are the pillars for achieving this
target.
Looking forward, we have a unique opportunity
to grow and lead our industry to greater heights
with a strong focus on our customers; a culture of
innovation and collaboration; a platform for our
employees to realize their potential and make a
strong impact on society. We continue to invest in
new technology and building people capabilities.
We remain a performance-driven organization
that believes in excellence and rigor in everything
we do.

13. [The inclusion of 100,000 women in its

should be extremely proud of.The ability of
women to pay attention to detail, the
sheer constraint of balancing one’s family
and work, and most importantly, the
dedication that women bring in is
absolutely phenomenal.

The Workplace
of Choice
The one moment that stands out vividly is
when the first delivery center in Delhi
was assessed at CMM Level 5. It was the
result of two long years of unrelenting
effort, unstinted support, and
commitment from the management,
delivery teams, and the quality group. It
was an onerous endeavor that, above all,
unified and drove the entire center
passionately toward a common goal.

17. Fit4Life motivates employees to participate in
physical fitness activities.
Launched by the CEO in May 2014, SafetyFirst
targets making the company a zero fatality
organization.
In today’s economic scenario,
employee wellness is no longer
desirable, but pivotal to an
organization’s long-term success.
However, the pace of life often
deters people from taking up
activities for improving health. If
the concept of improving health
and wellness is coupled with
improved bonding and
camaraderie among co-workers
as well contributing to a social
cause, I am convinced many
professionals will be proud to be
associated with such an initiative.

independent and assertive entrepreneurs.
Surekha, a housewife in Waze village of
Maharashtra, was inducted into TCS Maitree’s
Women Empowerment Program.
Surekha became the breadwinner for her family
of six. She learnt to make products such as
shopping bags and clothes. Soon, all the women
in the group began following Surekha’s lead,
which helped them increase their earnings.
Today, through TCS Maitree's Women’s
Empowerment Program, a unique bond has
developed between these women, who know
that they can depend on each other in times of
need.
Says Kanchan, a beneficiary of the program,“TCS
Maitree volunteers have taught us tailoring,
stitching, embroidery, and how to make paper
products. Ours is the first bachat gat (a self-help
group) in which all the women earn a decent
remuneration on a regular basis.”

these areas.
