Implement is the word used but it does not fit. ITIL is as simple as forming some kind of recognizable business management practice that can sustain or track more differential IT efforts which are becoming the norm these days. Oh, and getting some of the workgroups working together, very important, which is how places like Apple and Microsoft make a living. It used to be you just called one or two vendors for everything, now we have like 20 different workgroups, load balancing servers, clustering, massive hard drive banks that are basically just expensive junk eating power and keep track of mostly stupid stuff, like money, who owes who what, and why. That's what made tapes so nice, it's an ownership thing.

So you spend the wad buying more stuff to keep track of even more stuff, and the world just keeps going round and round, which keeps all us IT saps in a job.
