In evaluating the utility of action plans for addressing feedback comments during document review, researchers found that action plans are generally considered more helpful than the original comments alone. The preferred type of action plan depends on the document's stage and the comment's nature. For early-stage drafts, unstructured plans are often preferred because they offer flexibility for reflection-oriented or deliberation-oriented comments. Conversely, for concrete revision tasks, vocabulary-based planning is preferred because it provides granular, actionable steps.
