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 term bottleneck is often used in conjunction with a manufacturing facility and refers to a point in the production process where product bunches up, then slows down or stops completely. For example, if two conveyor belts merge into one, the point where they merge is the bottleneck.
