Ramp up has a minor spelling rule that people often miss. The verb and noun use different forms, although both contain the same two words.
Write the verb as two separate words without a hyphen: "ramp up," "ramps up," "ramped up," "ramping up." The noun is countable and hyphenated: "a ramp-up," "the ramp-up period," "a six-month ramp-up." Do not hyphenate the verb or leave the noun open.

Learn "Ramp Up" in depth →Why this trips up advanced learners specifically
Advanced learners often mix up these spellings because only a hyphen separates them. No vocabulary difference signals the problem. This small typographic choice is easy to reverse.
The rule, isolated
This is not a rare edge case. Both forms often appear in planning documents, project updates, and budget memos. Writers may switch between verb and noun uses within one paragraph. They can easily apply one spelling to both uses. The basic rule is simple: if the phrase is a verb, keep it open.
Correct: "We will ramp up hiring next quarter." -- Wrong: "We will ramp-up hiring next quarter."
If it is a noun, hyphenate it. Also use the hyphen when it modifies another noun, as in a ramp-up plan.
Correct: "Engineering budgeted an eight-week ramp-up for the new deployment pipeline." -- Wrong: "Engineering budgeted an eight-week ramp up for the new deployment pipeline."

Start the "Ramp Up" learning path →The noun form is countable, too
The noun form is also countable, similar to another planning period.
"Ramp-up costs came in under budget this cycle."
You can say "a ramp-up" or "several ramp-ups." Once hyphenated, it acts like an ordinary noun and takes articles or plurals normally.
Two separate mistakes, not one
The error can run in both directions. One mistake hyphenates the verb, while another leaves the noun open. Before choosing, check the phrase's grammatical job in the sentence. Is it an action, with no hyphen? Or is it a thing, with a hyphen?
Try replacing the phrase with a single synonym. If "increase" or "grow" fits naturally, the phrase is a verb and needs no hyphen. If "period," "phase," or "buildup" fits, it is a noun and needs the hyphen. This quick check can catch either error. You only need to identify the phrase's job in that sentence.
