Keys to Collaboration
Fieldstone Alliance has a great piece on the keys to collaboration you might find useful. Aside from outlining the 4 areas needed for collaboration, it also has a section on elements of successful collaboration that might be of particular interest. Best of all, as with so many of their resources, it's written concisely, with lots of bullet points for easy digestion. My only beef with their stuff is that they don't offer printable views.
BTW, if you're on Facebook, Fieldstone Alliance, through their page, is promoting several of their tools this week, including the one mentioned here.
