This white paper on collaborative workplaces perhaps covers familiar ground but may still be work circulating around the office email, especially for the quiz part way through and the selection of techniques to improve collaboration. The authors identify three types of collaborative environment: team, community and network. George Siemens criticizes this by saying "all forms of interaction are network based. Groups, collectives, teams, communities, etc. The underpinning structure is a network." I would take exactly the same tack, though I'm also a little uncomfortable with the way they divide up the world (not that the taxonomy matters - what is important are the mechanisms and the structures).
