Procedure: because of the fact that a developmental edit is the most extensive type of editing, two editors will work on your manuscript. This provides you with two pairs of experienced eyes to deliver the best edit for your manuscript.
How it works: a developmental editor goes through your manuscript to give their feedback on the manuscript as a whole, inclusive structure, tone of voice, and possible plot holes/fixes. A second editor then works on the manuscript to revise the developmental editor’s suggestions and to check for grammatical errors and possible additions to the editor’s feedback.
In conclusion, both editors will discuss their findings and provide the author with their feedback as well as the edited manuscript.
