I am recycling here this nice post of Temu on this subject. He made a nice table analyzing collaboration by looking for what are the objects (some people call them artifacts) worked out, how are the scripts (processes) handled and what is the density of communication in the systems.

I think this summary is neat and simple but yet useful to distinguish and see the ordering of the different levels. One thing missing though is a link back to the theoretical framework for each level.
