The big move |

I like the quote

Of course, managed services don't suit all schools. One of them is Tollbar business and enterprise college, New Waltham, Grimsby. "We did not want an ICT managed service for a lot of reasons," argues principal David Hampson. "I run a successful school. We have seven technicians, and an ICT manager who is part of the management team because I run the school as an education business. We have all our own very advanced systems.

"The premise is that if an ICT managed service is put into a school, it is cheaper for the school to join the service than to run its own ICT. This school [succeeds] because we want to control our own decisions."
If I had 7 technicians I won't need a managed service either I would already be one !!!
