This option increases the bottleneck rate r_b, which can be achieved by the following general methods:

• Process improvements
• Yield improvements
• Rework reduction
• Staffing changes
• Work-sharing, that is pass some tasks between stations

 Graphically, the impact of speeding up the bottleneck can be depicted as:
 

 
Note:

The benefits of the capacity increase can be realized via increased throughput, decreased cycle time, or a combination of both.

By Little's Law, increasing TH for constant WIP, or reducing WIP for constant TH means that cycle time will also be reduced.
