In the [[Theory of Constraints|Theory of Constraints]] from Goldratt, production processes are seen as constraints.Each process is either a bottleneck (constraint where flow < demand), or a non-bottleneck.
either a ''bottleneck'''s or ''non-bottleneck''. Bottleneck insights:
* Bottleneck flow should be equal to market demand. Use bottlenecks at 100%. No idle time.
* Bottleneck throughput equals plant throughput. '''An hour lost at a bottleneck is an hour lost to the whole system'''. An hour saved at a non-bottleneck is irrelevant.
* Cost of bottleneck is the cost of the entire plant divided by number of bottleneck hours available.

To increase bottleneck throughput:
• Keep machine continuously manned. New lunch rules. Extra workers. Immediate maintenance.
• Put quality-control checks in front of machine to prevent working on rework items.
• Reduce load on bottleneck. Activate older machines to augment bottleneck machine.
