2. Exploit the system's constraint: Ensure the bottleneck is at 100% capacity utilization or throughput.
3. Subordinate everything else to the above decision: Communicate the bottleneck
4. Elevate the system's constraint: Determine how to increase the bottleneck's capacity
5. If a constraint has been broken, go back to step 1. Do not allow inertia to cause a system's constraint.

has been identified and overcome, another constraint will become a bottleneck to the system.
