Final answer:
The revision stage allows reshaping documents in the writing process, which is recursive, not linear, allowing movement between brainstorming, drafting, researching, organising, and revising as needed.
Step-by-step explanation:
The revision stage allows you to reshape the documents as they come through the pipeline. When you engage in the writing process, you find that it's not a strict progression from one step to the next. Instead, it's a recursive process. This means that at any point while you're writing, you might shuttle back and forth between different stages such as brainstorming, drafting, researching, organising, and revising. This flexibility is a crucial part of developing your composition as it enables you to refine your ideas and arguments by returning to earlier stages as needed for further development or clarification.
