Ginni Rometty leaves complex legacy as she steps away as IBM CEO

When Ginni Romettysteps down as CEO at IBM in April and her replacement Arvind Krishna takes the helm, more than eight years will have passed since she took the reins at Big Blue. The executive helped lead a massive transformation, but IBM has had a bumpy financial ride throughout her tenure — at one time recording an astonishing 22 straight quarters of declining revenue.

To be fair, Rometty took over at a tumultuous time when technology was shifting from on-prem software stacks to the cloud. She saw what was coming and used the company’s considerable cash position to buy what she needed to make that switch while taking advantage of IBM’s extensive R&D to build other pieces in-house. But the transition took time, which resulted in some financial missteps.

She deserves credit for trying to move the battleship in a new direction — culminating with the $34 billion purchase of Red Hat — even if the results were ultimately mixed.

Leading the way

Rometty was the first woman to lead IBM in an industry where female CEOs are scarce. When she came on board in 2012, there were just 21 women running Fortune 500 companies; last year, that number had risen to 33, still a paltry 6.6%. Along with Safra Catz at Oracle and Lisa Su of Advanced Micro Devices, Rometty has been part of a small group of female CEOs at large technology companies.
