How many Nines?

Vijay: "Lost Revenue at 5-9s availability is 120,000.00 and lost revenue at 6-9s is 12,000.00. The delta is 108,000.00. Which is less than 1FTE (loaded cost). So there is no reason to go to 6 nines at that revenue number if it requires more than 1 FTE worth of work to be done. Full model is here."
