• There are two different types of bottlenecks: - Capacity contraint resource - a resource limited by capacity, like a bottle - non instantly available resource - a resource that is not available all the time

6. 6. 8 cars / min<br />4 cars / min<br />With less work-in-progress<br />Shorter cycle time<br />Or<br />Higher throughput<br />

15. 15.
16. 16. Capacity = 4<br />Capacity = 6<br />Capacity = 6<br />Throughput = 4<br />You can never go faster than your bottleneck<br />No need for higher capacity after the bottleneck than at the bottleneck<br />Higher capacity in front of the bottleneck will lower total throughput<br />
