Best Buy has gone through a management shake-up to "sharpen strategic initiatives and accelerate focus across the company."

Shari Ballard (pictured right) will lead Best Buy’s International business and Mike Vitelli will assume responsibility for Best Buy’s Domestic business, effective immediately.

Previously, Ballard and Vitelli shared the role of president of the company’s Domestic business and had additional responsibilities for operations in Canada and Mexico.

“To make the most of the profitable opportunities we see both domestically and internationally, we are establishing dedicated responsibility with two of our senior executive leaders, Shari Ballard and Mike Vitelli,” said Best Buy CEO Brian J. Dunn.

“The focus, energy and drive of these two leaders will serve us well as we accelerate the pace of our company’s transformation, work to provide more compelling multi-channel experiences for our customers and employees around the world and improve returns for our shareholders.”

In Ballard’s new role as Best Buy International executive vice president and president, she has responsibility for the company’s businesses in China, Canada, and Mexico, as well as overseeing management of the company’s interests in the Best Buy Europe venture.

In his role as Best Buy US executive vice president and president, Vitelli assumes full responsibility for the company’s domestic business groups and channels. Vitelli’s key focus areas will be creating a seamless customer experience across all channels, accelerating operational enhancements that will grow higher margin sales of connections and services and continuing to unlock opportunities to drive improved returns for the company and its shareholders.
