_(historical note: this is the second part (the first is here) of an article I wrote for IT Manager’s Journal, which published it at the URL http://management.itmanagersjournal.com/management/04/12/07/2312226.shtml?tid=84 on December 14, 2004. When I rediscovered the original text on my hard drive, on December 29, 2013, I put it back here with the original date as reference, since that whole website was closed years ago)_
