The Big Data Job Boom
By John R. Platt
Everywhere you go, everything
you do, you're generating data, and so is
everyone around you. Your mobile phone usage,
your internet browsing behavior, the way you
drive your car, the number of times you buy
turkey at the grocery store...all of that data
is being collected and used by companies around
the world. The massive growth in this
information which has exploded in volume,
velocity and variety has given rise to a new
name for a new field: Big data.
But the explosion of data has
also given rise to a tremendous need for skilled
professionals capable of dealing with all of
this information. In fact, the numbers of people
needed in big data are simply staggering.
According to one new projection from
McKinsey & Company, the U.S. alone faces a
shortfall of 140,000 to 190,000 big data
professionals in the next five years. Another
recent study from
Gartner suggests that 4.4 million IT jobs
worldwide will be needed to support big data by
2015. That's a lot of potential employment for
the right people.
Too Much Data, Not Enough
But where will all of these new
employees come from? While some of those
thousands or millions of people will likely end
up working in traditional areas such as storage
or infrastructure or security, experts say the
data scientists that are truly needed to make
sense of all of this data remain a rare breed.
"The ability to successfully
harness big data requires a unique combination
of skills and attributes," says Richard Rodts,
manager of global analytics academic programs at
IBM. "On the technical side, it's essential to
understand how to operate analytics technology
solutions to read into the data for hidden
insights and build predictive models that help
business decision-makers chart smarter courses
for their organizations." Beyond that, it's
important to understand the business model and
culture of your company or client so you can ask
the right questions of your data. And then,
Rodts says, "there are the very human
attributes, such as a knack for both strategic
and creative thinking, the ability to
collaborate with colleagues across the business,
and strong communication skills that enable you
to convey data-driven findings to senior
decision-makers in a compelling way."
That's a lot of skills for a
single person. As Mark A. Herschberg, CTO of
Madison Logic puts it, "That combination
doesn't exactly grow on trees."
So What Does a Big Data
The roots of big data lie in the
older, still valid term business intelligence.
"Big data is just business intelligence on
steroids," says Marty Carney, CEO of
WCI. "People doing BI data warehousing can
do big data. They just need more experience
dealing with bigger data sets and larger
Rodts takes it a bit further.
"Data scientists or analytics professionals are
part digital trend-spotter and part
storyteller," he says. "These are people, teams
and centers of excellence at businesses and
organizations who sift through vast amounts of
data to uncover insights that can yield
revenue-growing opportunities, spot risks before
they occur, save money, time and even lives."
The exact tasks for a big-data
professional can vary depending on the goals at
a particular company or project. "We start with
a very simple question," says Samer Forzley, VP
of marketing at the data-management company
Pythian. "What are you trying to achieve
from a business point of view? Are you trying to
save money? Are you trying to increase revenue?
Do you need to create insight on the fly? Are
you trying to create a condition engine on your
website that will recommend other products?"
Each answer has a different set of solutions, he
Meanwhile, a lot of the work
being done in big data today isn't directly
analysis but the transition from older systems
in silo, legacy databases. "The biggest enemy of
big data is silo data," says Ali Riaz, CEO of
Attivio. Companies may have been collecting
disparate forms of data in various silos for
years, but getting the full value of that
information is a step many aren't ready to take.
"When we talk about big data, we're talking
about actually pulling all of your structured
and unstructured information assets together,"
Riaz says. "We can't get to the big-data goals
if everyone is married to smaller data."
To help address the need for big
data professionals, several universities around
the country have added new data analytics
programs. Some, like the program at the
University of Tennessee, focus not just on
the technology but the business side of big
data. "We think it is really important that our
students have the technical skills, but that
they also have some business savvy and
understand the importance of subject-matter
expertise in deciding both how you collect the
data and how you will analyze it," says Dr.
Kenneth Gilbert, head of the university's
business analytics department. Toward that end,
the school's MS in business analytics program
includes concentrations on teamwork, giving
presentations to managers, and related skills.
For coursework, the best place
to start is with statistics, says Dr. Olly
Downs, senior VP of Data Sciences at
Globys, who recently helped assemble the
curriculum for the new data sciences certificate
program at the University of Washington. But
statistics alone isn't enough, and Downs
suggests that students get to know distributed
computation and programs such as Hadoop, Python
and R. At that point, you can "start getting
into data and visualizing it and gaining insight
from it," he says. The next step is to start to
understand how to communicate and visualize the
output of your data, since a key part of every
data scientist's job is getting managers to
understand their conclusions.
Unlike more traditional data
fields which often specialized in a single
tool working in big data requires a broad
knowledge base. "You can't know just one tool,"
says Riaz. "You have to be multifunctional. You
have to be multidimensional."
Even with the need for
multidimensionality, Riaz suggests finding the
big-data specialty that appeals most to you by
talking to data scientists who are already in
the field to see what they do. "Then you map it
to who you are," he says. "Are you an
infrastructure guy, or are you a board-level
guy? Do you want to interact with people? Do you
want to educate? Do you want to consume? Do you
want to make decisions? Do you want to enable?
Do you want to drive?" He suggests talking to as
many people as you can, being open to trying new
things, and applying for internships. "Don't get
in a decision mode until you have finished your
Once you're in the field, it's
important to keep moving forward. "Get into a
continuous learning mode," Riaz says. "What it
means to be a data scientist today is going to
radically change the next time a big new
technology comes your way."
Although companies area already
basing more decisions than ever on data, experts
say the full scope of how big data will impact
business remains to be seen. "I have a colleague
who compares the whole big data thing to
Eisenhower's interstate system," Gilbert says.
"It's going to create business opportunities
that people can't even imagine at this point."
But even with its rapid growth,
big data may actually be due for a shakeup in
the next few years. In part, because it is so
new. "Big data is in a way not fully defined yet
because it is still emerging," Forzley says. The
rapid expansion we see today could eventually
cause a similar contraction as processes work
themselves out and as companies realize that
they may have hired too many people. "We're
going to find efficiencies," says Riaz, who
expects the short-term projections of the number
of people needed in the field to fall
considerably by the end of the decade.
According to Downs, the role of
data scientists will continue to evolve. "Data
scientists are no longer going to just be
modelers and visualizers of data," he predicts.
"They will also be creating near-product-worthy
pieces of software that a software engineer can
then integrate into a bigger system."
Experts say the future of the
field could bring more regulation to protect
consumers' data, but it will certainly require
more security. "Now that we're housing more
sensitive information, you're going to have to
have more locks on your door and more gates
around your castle and more guard dogs and
policemen," Carney says. "The securitizing of
big data is going to be a huge business," he
The biggest risk for the future
of big data may be entrenched business practices
that don't yet see the value of analytics.
Gilbert points at McKinsey's study, which
predicts a need not just for a few hundred
thousand big-data professionals but also for 1.5
million data-savvy managers. "What is going to
determine the winners and losers in the business
world are the ones that learn how to use this
new resource for strategic advantage," he says.
