Group Work and Collaborative Writing 
Working with a group on a project can be a pleasure: responsibilities are equitably divided, the tedium of work is punctuated by conviviality and commiseration, and large problems dissolve under scrutiny from a variety of perspectives. Working with a group can also be frustrating, the seemingly indirect and digressive, as well as anxiety-ridden and inconvenient. But still, the product of group work has better odds for success than does the product of an individual.
