Forgive me if this is an existing mode of writing that I am unfamiliar with.
A Progressive/ Collaborative Literary Work would be developed by a group of writers. A subject would be agreed upon (or it could be looser depending on the intended outcome) and then the participants established. The first person would begin the work. Perhaps each person could write a chapter of a book for example.
After the worked was deemed complete (the last person added their part), the first person would make edits, then sequentially each contributor would make edits. The process could be repeated or changed as desired until the group agreed that the work was ready to be considered for publishing.
I think some key factors to the project’s success would be:
-Choose the group carefully (make sure you can work well with the group members and admire the quality of their work)
-Establish and stick to deadlines
-It will be what it will, you can’t control the outcome, it may take a while to get a rhythm going between the group members
