I think that Patrick has pointed out a central difficulty in your planning--if the writers arrive with what they consider a finished product then you will not get an integrated product--if that is waht you are aiming for. I suggest that you consult some of the texts on project management that exist in professional communication texts. These texts attempt to articulate the kinds of group practices that exist in organizations--and they will also point to some of the problems you might encounter in terms of group dynamics. The texts will, however, provide you with several different models. Some models suggest for example that you divide the various writing tasks, that you build recursion into the process (time for editing) etc. They will be useful espcially for your real audience--the instructor you are dealing with.
