what is a bottleneck in a manufacturing process
Bottleneck (production) In production and project management, a bottleneck is one process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain. The result of having a bottleneck are stalls in production, supply overstock, pressure from customers and low employee morale.[1] There are both short and long-term bottlenecks. Short-term bottlenecks are temporary and are not normally a significant problem. An example of a short-term bottleneck would be a skilled employee taking a few days off. Long-term bottlenecks occur all the time and can cumulatively significantly slow down production. An example of a long-term bottleneck is when a machine is not efficient enough and as a result has a long queue.[2][3]
Manufacturing in the United States The largest manufacturing industries in the United States by revenue include petroleum, steel, automobiles, aerospace, telecommunications, chemicals, electronics, food processing, consumer goods, lumber, and mining. A large portion of U.S. industrial output, the United States leads the world in airplane manufacturing. American companies such as Boeing, Cessna (see: Textron), Lockheed Martin (see: Skunk Works), and General Dynamics produce a vast majority of the world's civilian and military aircraft in factories stretching across the United States.
