A manufacturing bottleneck is a constraint or choke point that limits production output. Many manufacturing operations suffer from bottlenecks caused by one or more machines and the bottleneck may change depending upon the actual product being manufactured.
The essential difference between bottleneck and founder effects is that a bottleneck is a subpopulation caused when a natural disaster reduces the size of an original larger population, while a founder establishes a subpopulation as a new colony drawn from a larger population.
