BENTONVILLE, Ark. — Walmart has made several management changes in its merchandising division, including the promotion of Scott Huff to executive vice president overseeing U.S. merchandising operations.

The changes were announced in a company memo sent by chief merchandising officer Duncan Mac Naughton.

Huff, who most recently oversaw consumables for Walmart U.S, joined the retailer as an intern in 1994. The company named 13 merchandising executives in all, seven of whom are women, in areas including consumables, sales innovation, baby products and adult beverages.

The goal is to speed growth and boost efficiency, Mac Naughton said in the memo.

“We continue to talk about the changing customers, recognizing their needs and more efficiently serving them,” he wrote. “These moves provide a more specialized service to our customers, while also creating better alignment and a greater visibility across our business.”

The changes include the appointment of Michelle Gloeckler as executive vice president of consumables and U.S. manufacturing leader. She had been senior vice president of home and head of Walmart’s domestic sourcing initiative.

Last year the retailer pledged to support U.S. manufacturing by buying an additional $50 billion worth of American-made goods over the next decade. Gloeckler has worked at Walmart for five years, following more than two decades at Hershey Co.

John Aden was named executive vice president of sales innovation for the U.S. He had overseen Walmart’s merchandising services.

The moves in the merchandising division come on the heels of executive changes in the international division. The company has appointed Dirk Van den ­Berghe as chief executive officer of Walmart Canada. Van den ­Berghe comes to the post with 30 years of international business experience, including serving most recently as CEO of food retailer Delhaize’s operations in Luxembourg and its home country of Belgium.

Van den Berghe succeeds Shelley Broader, who was recently promoted to executive vice president, president and CEO of Walmart EMEA, giving her responsibility for the retailer’s operations in Europe, the Middle East and Sub-Saharan Africa.

The company also announced in April that Greg Foran, the CEO of Walmart’s Chinese unit since 2012, would take over as president and CEO of Asia. He succeeded Scott Price, who is moving to the discounter’s headquarters as vice president of international strategy.
