Planning. You only buy systems from the same shortlist several years
on a row because you know the maintenance burden associated with new
configs overweights their short-term advantages (that also gives you
volumes to negociate prices with hardware vendors).
But in serious number crunching the decision of hardware planning is
not left to the IT staff, but the project managers themselves.
We're talking two kind of hw here, simple desktops, where you can
recycle them every second or third year and clusters/mpp systems that
do the hard work.
