Fifty-seven percent of organisations that responded to this survey reported they have a policy of considering open source software and 8% had a policy of preferring it. A further 8%, however, had a policy of not using it at all.
In more than half of responding organisations, up to 20% of servers had open source software. In more than a third of responding organisations, up to 20% of desktops had open source software other than operating system or 'Office' suite software.
Mostly, open source software is supported by internal staff (40% of respondents), but others use both internal and external staff (24%) or exclusively external staff (23%). Larger organisations were more likely to use exclusively internal support.
