The author plays an important role in the substantive editing process, as they are the ultimate decision-maker when it comes to changes made to their manuscript. However, the author should also be open to feedback and suggestions from the editor, as the editor's job is to help the author improve their work and make it more effective. Collaboration between author and editor is key in substantive editing, and the author should be willing to consider alternative approaches or solutions suggested by the editor. Ultimately, the author should be satisfied with the final product, but should also recognize the value of professional feedback and expertise.
