Hugo Boss AG said Monday that chief operating officer Hans Fluri will step down by March 31 to become chairman of Red & Black Lux S.à r.l. on April 1. Red & Black is the parent company of Valentino Fashion Group S.p.A., which is the main shareholder of Hugo Boss AG. Klaus-Gerhard Bierbrauer will succeed Fluri and will focus primarily on purchasing, production and logistics. For the last eight years, he has been part of the operations team at Gucci Group, where his responsibilities included product management; purchasing and procurement; supply chain management; quality and production management, as well as logistics. Before that, he had stints in operations management with Jil Sander and Louis Feraud.
