Bottleneck Station

Cycle Restriction

Time spent at the slowest machine prevents the rest of the line from reaching its full potential. When a bottleneck station operates at ninety units per hour, a downstream machine capable of two hundred units per hour will inevitably sit idle for half of its shift. Operators focus their maintenance efforts here to ensure that no further time is lost.

Buffer Accumulation

Work in progress naturally builds up in front of the most constrained part of the process. Managing the queue before the bottleneck station ensures that the machine never stops due to a lack of material. Excessive inventory at this stage indicates that upstream processes are running too fast for the system to handle.

Production Ceiling

Investment in secondary equipment elsewhere provides no benefit until the primary restriction is addressed. Any upgrade that ignores the bottleneck station fails to change the final delivery schedule. Total system capacity remains fixed until the constraint moves to a different location.
