"The bottleneck to hitting our Q3 target is onboarding capacity, not demand."

Calibration against a one-off delay
"One missed handoff last week wasn't a bottleneck — it was a delay. The recurring bottleneck is still the legal review queue."
Practice scenarios
Practice using bottleneck in situations like:
- writing a status update that names a bottleneck without assigning blame to a person
- distinguishing a recurring bottleneck from a one-off delay
- describing a technical bottleneck to a non-technical stakeholder
- connecting a bottleneck to a specific business decision about where to invest next
Useful practice phrases:
- "The bottleneck is in [stage], and it's affecting everything downstream."
- "This step depends heavily on [person/system], which has made it a bottleneck."
- "That was a one-off delay, not a bottleneck — the recurring one is still [stage]."
- "What's bottlenecking [outcome]: [cause A] or [cause B]?"

Each sentence names a proposed limiting point. Good analysis should test that claim with data and observe what changes after the limit is addressed.
Use bottleneck for a constraint on flow or capacity, not merely any problem. A short delay can still cause a temporary bottleneck, while a recurring delay may have several causes.
