Bottleneck names a point that limits the flow of work. A complex process may have more than one bottleneck. Not every slow or annoying step is a bottleneck. The words around the term also matter. Some verbs and prepositions are much more common than others.
Common verb pairings include identify/find/locate the bottleneck, become/create a bottleneck, and remove/eliminate/ease/resolve the bottleneck. Use a bottleneck in [stage] to name its location. Use a bottleneck to [growth/scaling] to name what it limits. The form "a bottleneck of" is not the usual choice for these meanings.

Learn "Bottleneck" in depth →Diagnosing register: finding and naming it
Before a team can address a bottleneck, it must find and study it. The verbs here describe that work.
"We need to identify the bottleneck before adding more people, and right now the bottleneck in the approval flow is the single compliance reviewer who has to sign off on every contract."
"Identify the bottleneck" is a common opening phrase. "A bottleneck in [stage]" names where the limit occurs. For example, it may be in the approval flow, fulfillment, or onboarding.
Resolving register: naming the fix and the effect
After the team finds the bottleneck, it can name a possible fix and the work being limited.
"Manual testing has become a bottleneck for the release, so we're trying to ease it by automating the first review -- it's become a real bottleneck to scaling the team."
"Ease/resolve/remove the bottleneck" describes an action or intended result. It does not promise that the action will solve every delay. "A bottleneck to [growth/scaling/expansion]" names the larger activity being limited. The passive form "is bottlenecked by" also appears: "the release is bottlenecked by manual QA testing."

What doesn't collocate
Two problems are common. First, the verb "make" sounds awkward here: "this new hire will make a bottleneck in the review process." Use create, cause, introduce, or become instead. Second, "there's a bottleneck of the approval workflow" uses the wrong preposition for the intended meaning. Use "bottleneck in" to name the process stage. Also, do not call every one-time delay a bottleneck. A late client call is only a delay. A review queue that often holds up requests may be a bottleneck.
Practice scenarios
Practice using bottleneck in situations like:
- naming the one recurring point that caps throughput, not every inconvenience
- choosing "in" over "of" when naming which stage the bottleneck lives in
- describing the fix with the right verb -- ease, resolve, remove -- rather than "make"
Useful practice phrases:
- "We need to identify the bottleneck before [next step]."
- "The bottleneck in [process/stage] is [cause]."
- "This has become a bottleneck to [growth/scaling/expansion]."

Start the "Bottleneck" learning path →A precise sentence pairs bottleneck with a verb that shows whether the team is finding, creating, or reducing the limit.
Choose the preposition by asking two questions: "Where is the bottleneck?" and "What does it limit?"
