Problem Statement

Technology engineering towers minimize impacts inside of their
domains, without regard to impacts on other groups.


Infrastructure consolidation focuses along technology fault lines,
with focus on minimizing the impact to the technology managers
without regard to the users or long
-
term business impacts of
particular business decisions. Technology refreshes focus on
technology resource optimization
vs

corporate resource
optimization.


Data
-
center / Storage / Network / Servers need to provide
flexibility to scale any layer up or down. A component re
-
factor
should be cheaper, in
-
sourcing / out
-
sourcing should be faster
and more dollar efficient thru time.


High
-
usage customers should do the most work, and work
should be linear in growth function, not exponential
