Well for some background, I'm an IT guy at a public library. We often get requests, but no/little reasoning behind them. We also don't get to meet (officially) with other departments and discuss what they want/need from us, other than maybe a few minutes to chat here and there. There's also no interdepartmental "suggestions box" sort of idea. I'd love to share ideas with and from other staff members. Connecting that with point #2 above, we have a committee that controls all policy and procedures, it's not the departments themselves that get to make it. As an IT department we have no onboarding/offboarding policy+procedure or a well defined updated policy for our public computers. I've been trying to push something like Slack to my manager but he's fairly apathetic to the idea. Even just more of an ability to suggest and get suggestions would be awesome.
