Optum Thought Leader Details Big Data Migration Basics for Enterprises

healthcare itOptum company UnitedHealth Group‘s Venugopal Adooparambil serves as business intelligence director for big data and advised enterprises looking to leap into big data analytics that migration also means training people and enlisting leadership support, ZDNet reported July 31.

David Braue writes how the big data consultant had led supermarket chain SuperValu's transition using Teradata's Aster Data analytics platform.

The company had wanted the shift to help make sense of and reap gains from 13 years' worth of customer purchases, behavior and other data.

Adooparambil, speaking at a Teradata analytics forum last month, said implementation took three months.

As senior lead for SuperValu's enterprise data warehouse, BI and big data at the time, Adooparambil said he had to identify team members who can be trained to become a “rock-star team with defined roles and responsibilities.“

He added, “If you're going to succeed in big data, you need a thick skin because you'll get a lot of pushback.“

The strategy of grooming in-house experts gave the IT team room to do its role.

“The data scientists should be able to manage their system; IT provide the transportation layer to help them load data fast, but we worked to build best practices, standards and governance within a business partnership to maximize business self-service,“ Adooparambil said.

He noted that independent vendors, clear business use cases and a leadership team that is on board with the idea of using a new data platform across the chain's 3,400 stores were also crucial elements of the project.

“It's a new paradigm for everybody, and when you're talking about “˜everybody' you've got to find people in IT, architecture and databases.“

He said one proof of concept the technology worked was when the team took 2.2 minutes to run 13 weeks worth of historical data to process a sales projection report, an effort that used to take 4 hours.
