Walmart Stores named former GE Power Chief Information Officer Clay Johnson as its new CIO and executive vice president for global business services, the Wall Street Journal reports.

Walmart’s new Global Business Services division is part of a larger reorganization of its corporate IT and e-commerce groups, combining security, back-office systems, and global shared services as a single group — now led by Johnson. The reorganization of business groups occurred a year ago after Walmart completed a $3.3 billion acquisition of e-commerce startup Jet.com.

The goal is to consolidate into a single technology group that can oversee the entire customer experience — both in stores and online, the Journal reports. It will also work to increase IT efficiency and improve processes for Walmart employees.

Walmart Labs, a division of Wal-Mart, is using cloud technologies to redefine e-commerce for the retailer. In August 2016 Walmart said it wants to start an OpenStack project around its OneOps software. OneOps is the company’s DevOps software that makes it easier to move applications from one cloud to another.

According to the Wall Street Journal, Walmart is shifting its focus to e-commerce.

At GE Power, Johnson was responsible for all IT initiatives and strategies for the business as well as driving the security strategy for the company. He has also held software and IT positions with companies like Boeing, Dell, Nortel, and FedEx.

Johnson is replacing Walmart’s CIO of five years, Karenann Terrell, who is leaving in February. Walmart did not say where she will go after her departure, the Wall Street Journal reported.
