A year after CEO Ginni Rometty announced a sweeping reorganization at IBM [itjungle.com], three top executives have left [infoworld.com], including Steve Mills, the IBM lifer who had led the Software Group since 2000. Mills played a major role in IBM's acquisition of dozens of companies [ibm.com] while building up the company's portfolio of server middleware and data center management software; starting in 2007, he led the company's move into the now-crowded fields of cloud computing and analytics [zdnet.com].
Also departing are Danny Sabbah, CTO for cloud computing; and Brendan Hannigan [forbes.com], GM of IBM's security group. Mills and Sabbah are both well into their sixties and may well retire, but Hannigan is younger.
IT Jungle (a neat little site that specializes in the business of IBM and other big iron vendors) notes that the Mills' old Software Group is now basically gone [itjungle.com], its pieces shifted into the IBM Systems group and the Cloud group, or into vertical industry stacks such as IBM Healthcare. Mills has spent the past year as the Executive VP nominally in charge of all of IBM's various software assets, an impressive title to be sure; but that reminded me of John Z. Delorean reminiscing [autonews.com] not so fondly of his final, brass ring job as Group VP at General Motors.
