Overhaul works as both a verb and a noun, and it's tempting to assume that once you've got one form comfortable, the other comes free. It doesn't.
The verb and the noun mean exactly the same thing. But each one carries its own grammar rules, learned separately, and a learner who is fluent with "overhaul the process" can still stumble on "needs an overhaul" -- and the reverse happens just as often.
Same idea, two different rulebooks
As a verb, "overhaul" is transitive and takes its object directly, with nothing in between:
"We're overhauling the onboarding process -- new tooling, new steps, new ownership."
As a noun, it almost always needs an article, and it's commonly paired with an intensifying adjective or followed by "of":
"The vendor-onboarding checklist is overdue for a full overhaul -- half the steps reference a system we retired last year."
Both sentences describe the identical kind of change. What differs is entirely mechanical: whether "overhaul" is doing the work of a verb or naming a thing as a noun, and each role comes with its own attached grammar.

"The internal approval workflow was completely overhauled after repeated delays were traced back to a single bottleneck step."
That's still the verb form, just in the passive voice -- a different construction again from the plain active verb and from the noun.
Where the two rulebooks collide
Because the meaning is shared, learners often import one form's grammar into the other by accident, and the errors run in both directions.
Bringing the noun's "of" into the verb slot produces something like "we overhauled of the pricing model" -- wrong, because the verb never takes a preposition before its object. Going the other way, dropping the noun's required article produces "the process needs overhaul" -- also wrong, because the noun almost always needs "an" in front of it.
Fixing one of these errors doesn't fix the other. They're separate habits built on separate rules, even though both rules attach to the exact same underlying word.
Practice scenarios
Practice keeping the verb and noun grammar separate in situations like:
- proposing a rebuild using the verb form, with no preposition before the object
- describing something as overdue for change using the noun form, with an article
- switching between the active verb and the passive construction in the same conversation
Useful practice phrases:
- "We're overhauling [X]." (verb, no preposition)
- "[X] is overdue for a full overhaul." (noun, with article)
- "[X] was completely overhauled after [reason]." (passive)
One word, one meaning, two grammars.
Learning the verb buys you the verb. The noun is a separate purchase.
