Retailer Wal-Mart Stores Inc today (7 June) confirmed to just-style that it has reshuffled executive responsibilities in its struggling apparel business in an attempt to rejuvenate sales.

The changes now mean that two executives are in charge of the unit.

Dottie Mattison, senior vice president and general manager of apparel, will be responsible for the Apparel Global Merchandising Center, including brand merchandising, product development and sourcing.

And senior vice president of apparel Lisa Rhodes, who previously reported to Mattison, is now taking on more responsibility while continuing to oversee category merchandising.

Mattison and Rhodes both report to John Fleming, executive vice president and chief merchandising officer.

Wal-Mart says the changes are aimed at bringing "apparel brand, product development and sourcing initiatives into greater alignment with the retailer's growth and productivity goals."

But they coincide with falling same-store sales at the Walmart chain in the US, and an admission by the retailer that its apparel business remains "a work in progress."
