ERP projects can take from six months to
several years to complete. During this time the IT
infrastructure and ERP software itself will evolve.
Firms should expect to do a technology roll about
every 24-36 months. What is a technology roll?
According to Moore’s law, CPU processing power
will either double in performance or its cost will be
cut by one-half approximately every 18 months.
By the time 36 months have passed, the technology
has become so much less expensive for the same or
more performance, that it is cheaper to replace it,
due to maintenance costs, than to retain the old
technology.
