JISC infoNet - System Selection infoKit

"System change is often prompted by seemingly insoluble problems with existing hardware and software and is often unwelcome both to those who have to cope with it and those who have to fund it. One of the themes running through many of the JISC infoNet infoKits is the opportunity afforded by system change to add value to the business of teaching, learning and research. This depends, of course, on selecting the right system in the first place."
