I work as part of a 8 man IT team on the helpdesk (but with a fancy title) and over the last few years have become increasingly frustrated and annoyed at our SysOps who constantly make changes to the environment outside of the designated weekend and do not communicate that these changes have been made. As a result, when things go wrong, the first I know about the changes is due to the calls from our users.

I have spoken to management about this lack of communication from the team and it may "resolve" for a few months before going back to the way it was, which then gets me fired up again which leads to another talk to management which leads to a few months of communication before the cycle starts again.

As a result, I am wondering how other IT teams manage internal communication of changes?
Or are we all dysfunctional and due to our industry none of us can communicate with each other?

{hopefully I have remained vague enough not to be identified should my colleagues also use Geekzone, but too bad if they do}
