I believe she is partly still there because anyone taking the role would be taking a poisoned chalice so to speak. They would have to release all the c-ap provisions and accounting tricks shes stored in her accounts to look good artificially, so why would anyone come to become her fall guy\gal.....unless they agree to pay them richly for the utter destruction of their career and reputation.
Keep smiling that cheesy smile Ginni you got it made ;-)
I believe it would be better for the company to fail a bit more such that it can then be reborn in its earlier image of "a reassuringly expensive organisation". Meaning they cost more .....but rest easy they always solve your problem and get the right result. Those days are long gone unfortunately along with most of the talent that built that reputation.
Today's IBM is competing at the bargain store level on cost and talent with offshore code monkeys supported by on-shore newbs, that actually cost more to manage, and frequently deliver mediocre results with everyone off to the legal courts to resolve. This often lack luster delivery is backed up with the most funny and colossal expenditure in marketing *ank. An algorithm is all that watson was, now it will change the tyres on your car....!
But most of the big players in the market are doing exactly the same, so now its time to go medium tier consultancy where a lot of ex IBMERs went.
