Martin Hoelz will take over from Klaus Hardy Muehleck as CIO of Thyssenkrupp July 1. The 47-year-old will also head the company's Group Processes & Information Technology (GPI) unit.

Hoelz has been with Thyssenkrupp since 2014. Most recently, he and Muehleck jointly headed GPI, which is tasked with implementing standards and optimizing and harmonizing business processes as well as the company's IT infrastructure.

Thyssenkrupp, a diversified steel company that is a big supplier to the automotive industry, said GPI is a key driver of digitization.

"We look forward to working with Martin Hoelz to develop the Group into a process-oriented and digitized company,” Thyssenkrupp management board member Guido Kerkhoff said in a statement.

Before joining Thyssenkrupp, Hoelz, who is a business IT specialist, was a senior partner at audit and consulting company Deloitte and held various management functions at Daimler and the VW Group.

Muehleck, who before joining Thyssenkrupp was the CIO of the Volkswagen Group, is leaving the steelmaker to take up a position in the German Defense Ministry.
