Developmental editing refers to a type of editing that focuses on improving the overall structure, content and flow of a written work. This type of editing is concerned with making sure that the manuscript or document is well-organized, coherent and easy to follow. Developmental editors typically look at big picture issues such as pacing, character development, plot lines, and overall storytelling techniques. They may suggest reordering sections, deleting unnecessary material, or adding new content to improve the work's overall effectiveness. Unlike copyediting which focuses on correctness of language and style, developmental editing is more concerned with making sure that a piece of writing effectively communicates its message to readers.
