It's the business risk of not being able to replace resources for a critical system and the fact that projects are exceedingly expensive and very slow because of dealing with an old spaghettilith (I just made that up!) architecture. Frankly, we need solutions to be delivered faster so we can "move at the speed of business" and this platform just isn't cutting it.

Is that worth $1 billion? That's above my pay grade and I'm glad I don't have to make that decision. For the record, our CFO doesn't think so - at least not until he's closer to retirement so if he gets canned for it he'll be alright! He's in his mid 50's now so we may have to wait another five years!
