Common mistakes
Mistake: "the bottleneck of the process."
For this sentence, "in the process" is usually clearer. Yet "of" can introduce what has the bottleneck. For example, "the main bottleneck of the system" is possible, though "in the system" may sound more direct. "Of" is also natural in phrases such as "the removal of a bottleneck."
Practice scenarios
Practice choosing the right preposition in situations like:
- locating a bottleneck inside a wider workflow ("in")
- pointing to the stage where work slows ("at")
- linking a constraint to growth or scaling ("to")
Useful practice phrases:
- "A bottleneck in [the process]."
- "A bottleneck at [the stage]."
- "The bottleneck to [outcome] is [constraint]."
