Developmental Editing

Ideally, developmental editing begins before the writing does. True to its name, developmental editing involves development of a book's premise, and the structural elements that support that premise: story arc, characterization, pacing, narrative voice, and style. 

Developmental editing continues throughout the writing process, to ensure the fulfillment of the book's premise, and the soundness of the structural elements. A strong framework is dependent upon the strength of its parts and the pieces that join them together.
