A good concept, like a good intention, is not enough. If you can't execute your ideas—communicate them through words or pictures—you do not have a viable book. Developmental editing involves reading your work carefully, analyzing the strengths and weaknesses of the writing, highlighting general and specific areas that need attention, and clearly articulating a direction for revision. It is an intimate, strenuous, time-consuming process, a creative dynamic that hones your skills and improves your work, not only the project you are working on but future projects as well.
