A bottleneck is a resource with capacity that is not sufficient to produce the quantities that the market demands. In this way the bottleneck prevents the company from making more money. (p.153 Critical Chain)
(see also Critical Capacity Resource (CCR))
An hour lost at a Bottleneck is an hour lost for the entire system. The Bottleneck determines the factory capacity. To lose time here loses throughput. An hour saved at a non-Bottleneck is a mirage |
