When Chewing on Big Data, Take Small Bites First

The difficulty of exploiting big data.

Many marketing researchers gloss over articles with “Big Data” in the headlines because the resources necessary to exploit Big Data are just too…big.

But the concept should encourage credit unions to think about the other data sets to which they have access and how to leverage them, say David Cooper and J. Paul Leavell in their report, “The Real Question is How Little is Little.”
 
Cooper is vice president of information systems for $287 million asset Charlotte (N.C.) Metro Federal Credit Union; Leavell is the credit union’s senior marketing analyst.
 
Big Data describes large volumes of high-velocity, complex, and variable data that are difficult if not impossible to manage and analyze within the existing frameworks of most companies.
 
Big Data can translate into a big payoff, but even companies with abundant resources should start by examining “Little Data”—information that can be captured and analyzed right away.
 
There’s a lot of low-hanging fruit here, Cooper and Leavell say.
 
If your credit union tracks automated clearinghouse (ACH) payees, for example, can you find insurance payees and leverage them to crosssell insurance products to members you know are using another firm?
 
Once you’ve capitalized on those opportunities, turn your attention toward “Middle Data”—information an organization collects but is not in a position to analyze, or would be able to analyze if it were available.
 
Consider that a credit union tracks debit, credit, and ACH transactions, including the amount and payee of each, but it doesn’t have the resources to put that information to use.
 
But if you knew which members had recent inquiries on their credit reports, staff could reach out to them for loan offers.
 
In weighing the return on investment for data projects, keep in mind that even moderate efforts can create efficiencies. Emphasizing these concepts can allow for more robust service to members and generate revenue streams in novel ways.

Great article! Unfortunately, most employees don’t feel valued or appreciated by their supervisors or employers. In fact, research has shown that the predominant reason team members quit their jobs is because they don’t feel valued. This is in spite of the fact that employee recognition programs have proliferated in the workplace – over 90% of all organizations in the U.S. has some form of employee recognition activities in place. But most employee recognition programs are viewed with skepticism and cynicism – because they aren’t viewed as being genuine in their communication of appreciation. Getting the “employee of the month” award, receiving a certificate of recognition, or a “Way to go, team!” email just don’t get the job done. How do you communicate authentic appreciation? We have found people have different ways that they want to be shown appreciation, and if you don’t communicate in the language of appreciation important to them, you essentially “miss the mark”. Additionally, employees need to receive recognition more than once a year at their performance review. Otherwise, they view the praise as “going through the motions”. A third component of authentic appreciation is that the communication has to be about them personally – not the department, not their group, but something they did. Finally, they have to believe that you mean what you say. How you treat them has to match the words you use. If you are not sure how your team members want to be shown appreciation, the Motivating By Appreciation Inventory (www.appreciationatwork.com/assess) will identify the language of appreciation and specific actions preferred by each employee. You then can create a group profile for your team, so everyone knows how to encourage one another. Remember, employees want to know that they are valued for what they contribute to the success of the organization. And communicating authentic appreciation in the ways they desire it can make the difference between keeping your quality team members or having a negative work environment that everyone wants to leave. Paul White, Ph.D., is the co-author of The 5 Languages of Appreciation in the Workplace with Dr. Gary Chapman.
