GE, which under Chief Executive Jeff Immelt has made a big bet on marrying software and analytics with its industrial products, will bring all of the digital capabilities from across the company into one organization, it said. The unit will be led by Bill Ruh, who has been GE’s software vice president and will become chief digital officer. The U.S. conglomerate also announced that Mark Begor, GE’s head of energy management, would retire after 35 years with the company.
