As seen in InformationWeek
Data is being used in and across more functional aspects of today’s organizations. Wringing the most business value out of the data requires a mix of roles that may include data scientists, business analysts, data analysts, IT, and line-of-business titles. As a result, more resumes and job descriptions include data-related skills.
A recent survey by technology career site Dice revealed that nine of the top 10 highest-paying IT jobs require big data skills. On the Dice site, searches and job postings including big data skills have increased 39% year-over-year, according to Dice president Shravan Goli. Some of the top-compensated skills include big data, data scientist, data architect, Hadoop, HBase, MapReduce, and Pig — and the pay range for those skills ranges from more than $116,000 to more than $127,000, according to data Dice provided to InformationWeek.
However, the gratuitous use of such terms can cloud the main issue, which is whether the candidate and the company can turn that data into specific, favorable outcomes — whether that’s increasing the ROI of a pay-per-click advertising campaign or building a more accurate recommendation engine.
If data skills are becoming necessary for more roles in an organization, it follows that not all data-driven rock stars are data scientists. Although data scientists are considered the black belts, it is possible for other roles to distinguish themselves based on their superior understanding and application of data. Regardless of a person’s title or position in an organization, there are some traits common to data-driven rock stars that have more to do with attitudes and behaviors than technologies, tools, and methods. Click through for six of them. [Note to readers: This appeared as a slideshow.]
They Understand Data
Of course data-driven rock stars are expected to have a keener understanding of data than their peers, but what exactly does that mean? Whether a data scientist or a business professional, the person should know where the data came from, the quality of it, the reliability of it, and what methods can be used to analyze it, appropriate to the person’s role in the company.
How they use numbers is also telling. Rather than presenting a single number to “prove” that a certain course of action is the right one, a data-driven rock star is more likely to compare the risks and benefits of alternative courses of action so business leaders can make more accurate decisions.
“‘Forty-two’ is not a good answer,” said Wolfgang Kliemann, associate VP for research at Iowa State University. “‘Forty-two, under the following conditions and with a probability of 1.2% chance that something else may happen,’ is a better answer.”
Data-driven rock stars are genuinely curious about what data indicates and does not indicate. Their curiosity inspires them to explore data, whether toggling between data visualizations, drilling down into data, correlating different pieces of data, or experimenting with an alternative algorithm. The curiosity may be inspired by data itself, a particular problem, or problem-solving methods that have been used in a similar or different context.
Data scientists are expected to be curious because their job involves scientific exploration. Highly competitive organizations hire them to help uncover opportunities, risks, behaviors, and other things that were previously unknown. Meanwhile, some of those companies are encouraging “out of the box” thinking from business leaders and employees to fuel innovation, which increasingly includes experimenting with data. Some businesses even offer incentives for data-related innovation.
They Actively Collaborate with Others
The data value chain has a lot of pieces. No one person understands everything there is to know about data structure, data management, analytical methods, statistical analysis, business considerations, and other factors such as privacy and security. Although data-driven rock stars tend to know more about such issues than their peers, they don’t operate in isolation because others possess knowledge they need. For example, data scientists need to be able to talk to business leaders and business leaders have to know something about data. Similarly, a data architect or data analyst may not have the ability to manipulate, explore, understand, and dig through large data sets, but a data scientist could dig through and discover patterns and then bring in statistical and programming knowledge to create forward-looking products and services, according to Dice president Shravan Goli.
They Try to Avoid Confirmation Bias
Data can be used to prove anything, especially a person’s opinion. Data-driven rock stars are aware of confirmation bias, so they are more likely to try to avoid it. While the term itself may not be familiar, they know it is not a best practice to disregard or omit evidence simply because it differs from their opinions.
“People like to think that the perspective they bring is the only perspective or the best perspective. I’m probably not immune to that myself,” said Ravi Ivey, chief data scientist at Ranker, a platform for lists and crowdsourced rankings. “They have their algorithms and don’t appreciate experiments or the difference between exploratory and confirmatory research. I don’t think they respect the traditional scientific method as such.”
The Data Science Association’s Data Science Code of Professional Conduct has a rule dedicated specifically to evidence, data quality, and evidence quality. Several of its subsections are relevant to confirmation bias. Among them are failing to “disclose any and all data science results or engage in cherry-picking” and failing to “disclose failed experiments or disconfirming evidence known to the data scientist to be directly adverse to the position of the client.”
They Update Their Skill Sets
Technology, tools, techniques, and available data are always evolving. The data-driven rock star is motivated to continually expand his or her knowledge base through learning, which may involve attending executive education programs, training programs, online courses, boot camps, or meetups, depending on the person’s role in the company.
“I encourage companies to think about growing their workforce because there aren’t enough people graduating with data science degrees,” said Dice president Shravan Goli. “You have to create a pathway for people who are smart, data-driven, and have the ability to analyze patterns so they have to add a couple more skills.”
Job descriptions and resumes increasingly include more narrowly defined skills because it is critical to understand which specific types of big data and analytical skills a candidate possesses. A data-driven rock star understands the technologies, tools, and methods of her craft as well as when and how to apply them.
They’re Concerned About Business Impact
With so much data available and so many ways of analyzing it, it’s easy to get caught up in the technical issues or the tasks at hand while losing site of the goal: using data in a way that positively impacts the business. A data-driven rock star understands that.
Making a business impact requires three things, according to IDC adjunct research adviser Fred McGee: having a critical mass of data available in a timely manner, using analytics to glean insights, and applying those insights in a manner that advances business objectives.
A data-driven rock star understands the general business objectives as well as the specific objective to which analytical insights are being applied. Nevertheless, some companies are still falling short of their goals. Three-quarters of data analytics leaders from major companies recently told McKinsey & Company that, despite using advanced analytics, their companies had improved revenue and costs by less than 1%.
