Knowledge Management for an IT Department?
Laurentiu asks: "In every IT department out there there's a wealth of heterogenous information floating around: code snippets, HOWTOs, FAQs, docs, spreadsheets, post-it notes etc. Asking Joe where he put that file won't work forever. So what is, in your experience, a good way to manage this knowledge? And what software would you recommend for such a task?"
We've been using MediaWiki for this exact purpose: http://www.mediawiki.org/wiki/MediaWiki. It's easy to install, a snap to manage, and makes it easy to share your knowledge with the rest of the world if that's something you want to do.
While we are probably going to end up with SharePoint (which isn't a bad collaboration tool if all your fellow staff members know is Word, Excel, and PowerPoint), I personally like the Plone Help Center. You can see examples on the Plone web site or on my personal web site.
