Developmental editing is the stage most authors have heard of but fewest understand precisely, partly because what it looks at genuinely changes depending on the type of book. This guide sets out what it covers for fiction, memoir, non-fiction and business books, what the feedback typically looks like, and when it is, and is not, the right next step.
What does developmental editing actually mean?
Developmental editing (sometimes called structural or substantive editing) is feedback on the manuscript as a whole: whether it is built well, whether it delivers what it promises the reader, and where the biggest problems are, before anyone spends time perfecting sentences that might later be cut entirely.
It usually happens after the author has revised the draft themselves and, ideally, after some initial reader feedback, and before copy editing. See what does a book editor do? for how it fits alongside other editing services.
What does developmental editing look at in fiction?
For a novel, this typically covers plot logic and cause and effect, whether the overall structure supports the story being told, character motivation and arc, pacing across the whole book, point of view consistency, and whether the stakes established early on are sustained and paid off.
- Plot
- Structure
- Character
- Pacing
- Point of view
- Stakes
Example
For example, a debut thriller had a strong opening and a strong ending but a middle section where the protagonist mostly reacted to events rather than driving them. Developmental feedback identified the missing agency and suggested where the character could make an active choice instead, without changing the ending at all.
What does developmental editing look at in memoir?
For memoir, the focus usually shifts to scope (which part of the writer’s life the book actually needs to cover), thematic coherence, chronology and how it is handled, narrative focus, and the balance between scene and reflection.
- Scope
- Theme
- Chronology
- Narrative focus
- Reflection
What does developmental editing look at in non-fiction?
For non-fiction, developmental editing typically examines whether the central argument is clear and well supported, whether the reader’s journey through the material makes logical sense, whether chapters build on each other, the strength and placement of evidence, and where material is unnecessarily repeated.
- Argument
- Reader journey
- Chapter logic
- Evidence
- Repetition
What does developmental editing look at in business books?
For business and expertise-led books, developmental editing often looks at whether the reader’s actual problem is clearly named early, whether any framework offered is coherent and usable, how the author’s authority is established without overclaiming, whether examples genuinely illustrate the points made, and whether the book helps the reader apply the ideas rather than only understand them.
- Reader problem
- Framework
- Authority
- Examples
- Application
What does developmental feedback actually look like?
Most developmental editing produces an editorial letter, a written document summarising the manuscript’s main strengths and problems and suggesting an approach to revision, alongside more specific comments placed through the manuscript itself, flagging particular scenes, chapters or arguments.
What is in an editorial letter?
Typically an overview of what is working, the two or three biggest issues the editor would prioritise, and suggested directions for revision, rather than a prescriptive rewrite. A good editorial letter explains reasoning, not just conclusions, so the author can apply the same judgement to future decisions.
What are manuscript comments used for?
Comments placed directly in the manuscript usually point to specific instances of a pattern raised in the editorial letter, or flag a local issue (a confusing paragraph, an unclear motivation) that does not need its own section in the letter.
Should I expect a major revision afterwards?
Often, yes. Developmental editing tends to surface the most significant, and sometimes the most time-consuming, changes a manuscript needs. It is worth allowing real time and energy for this stage rather than treating it as a quick pass before publication.
What does developmental editing not automatically include?
It does not usually include line-by-line correctness, grammar fixes, or a guarantee that every suggested change will be made for you. It is feedback and direction on the big picture; implementing the revision is generally the author’s work, sometimes with a second editorial pass afterwards.
When is developmental editing the right stage?
Developmental editing may be useful when
- The manuscript is complete, or close to it
- You have already revised it yourself at least once
- You have unresolved doubts about structure, pacing or argument
- Beta readers disagree about what the book is actually about
- It is your first full-length manuscript of this kind
When might it be unnecessary?
If a manuscript has already been through genuine structural feedback (from a previous developmental edit, an MFA-style workshop, or extensive beta reading) and revised accordingly, another full developmental pass may not be the most useful spend. An editorial assessment can confirm whether the structure is genuinely sound before deciding.
How is developmental editing different from copy editing?
Developmental editing asks whether the book, as a whole, works. Copy editing asks whether each sentence and paragraph is as clear and correct as it can be. Doing copy editing before developmental work risks polishing sentences that get cut or substantially rewritten once structural changes happen. See what is copy editing? for the detail.
Common mistakes
- Booking developmental editing on an incomplete manuscript. Editors can work on partial drafts, but feedback is usually more useful once the whole shape is on the page.
- Expecting line-level polish from a developmental edit. That is copy editing’s job; developmental work focuses on the bigger structure.
- Treating the editorial letter as a checklist to tick off literally. It is a diagnosis and a set of options, not a set of mandatory instructions.
- Skipping revision after developmental feedback and moving straight to copy editing. That risks paying to polish text that structural changes will later remove or rewrite.
Frequently asked questions
How long does developmental editing usually take?
It depends on manuscript length and the specific service, and timelines vary by provider; always ask for an estimate as part of any quote.
Do I need developmental editing before beta readers, or after?
Either order can work. Some authors use beta readers first to identify obvious problems cheaply, then bring the remaining, harder-to-diagnose issues to a developmental editor.
Can developmental editing be done in stages, chapter by chapter?
It is usually more effective on a complete manuscript, since structural problems in an early chapter can depend on what happens later in the book.
What if I disagree with the developmental feedback?
You are free to disagree. It is worth understanding the reasoning first, especially where more than one reader raises the same concern independently.
