I think pantsers get the most out of a reverse outline, not plotters. Disagreement is actually welcome!
I broke down the three documents a good developmentel editor actually hands you. The one that got the least love in the comments was the reverse outline, and I think that's backwards. So here's a longer take on just that one. Reader expectations is the lens I look through, so that's the angle. I'm not here to tell anyone how to write.
Fast version of what a reverse outline is, in case it's new: after the draft is done, you go back and write down what each scene actually does. Not what you meant it to do. What's on the page. Where the beat lands, whose head you're in, what changed by the end of it. You come out the other side holding the skeleton of the book you really wrote, which is almost never the book you think you wrote.
Plotter and pantser is a spectrume and nobody sits all the way at either end. But roughly: a plotter walks in with the map, so they can already see their structure whenever they want. A pantser flies without one. That freedom is where a ton of the best, most alive writing comes from and I'm genuinely not knocking it. The catch is that when you pants, you're inside the story the entire time. You never get to stand outside it and look at its shape. You finish the draft as the one person who can't see what you built.
Here's the part I keep chewing on. Nora Roberts is a pantser. She's said she just sits down and writes to find out what happens, straight through, and fixes it later "through a lot of experience." That last bit is the whole thing for me. She can pants safely because 200-something books have already put the reader's expectations in her head. She doesn't have to check the contract against the page, because the contract is already in her. Tia Williams plots. Different method, also works. Point is they both already know, cold, what their reader expects.
A newer writer pantsing the same way isn't doing anything wrong. They just haven't had the decade yet that turns that into instinct. So they're flying blind on a reader contract that lives in nobody's head, theirs included. And romance has a real contract. Readers expect certain beats to hit around certain places, and when they don't, the reader doesn't send you a tidy structural critique. They just quietly DNF and go find the next book.
This is the line I actually wanted to write the whole post around: the reverse outline is where a pantser gets to see how far they drifted from what readers expect. Not to beat yourself up over the drift. Some of your drift is the best thing in the book. But you cannot tell which part is the good kind and which part just wandered off, until you can see the shape, and the reverse outline is the cheapest way to see it without giving up pantsing at all. Write free. Then map what you made. Then you get to decide.
So don't skip it. And honestly, if you believe your best stuff comes out of pantsing, that's even more of a reason to embrace the reverse outline, because it's the thing that lets you keep writing that way and still catch the misses before a reader does.
That's my take. Editors, pantsers, plotters, tell me where I've got it wrong.
