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

particular business decisions. Technology refreshes focus on
technology resource optimization
vs
corporate resource
optimization.

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