When Ginni Rometty steps 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.
