Frequently Asked Questions
QWhat is bottleneck analysis in manufacturing?
Bottleneck analysis is the process of identifying the single constraint that limits total system throughput — the process step where capacity is insufficient to meet demand from upstream operations. Based on the Theory of Constraints, every system has exactly one binding constraint at any time, and improving any other part of the system does not increase total output.
QHow do you identify a bottleneck in a manufacturing facility?
The constraint is found by looking for WIP accumulation. Material piles up in front of the constraint because upstream processes produce faster than the constraint can consume. Walk the floor and identify where staging racks are consistently full, where queues are deep, and where operators downstream are waiting for parts — that is where your constraint is.
QWhat does it mean to exploit a bottleneck?
Exploiting a constraint means getting the maximum possible output from it without additional capital investment. This includes eliminating planned downtime during constraint time, protecting it from material starvation, cross-training dedicated operators, reducing changeover time, and improving first-pass quality at the constraint input. Exploit before you elevate (add capacity).
QHow often should you run a bottleneck analysis?
Weekly bottleneck analysis is the recommended cadence for most operations. The constraint can shift as improvement actions take effect, product mix changes, or staffing fluctuates. A 45-minute weekly review — measuring actual throughput rate at the current constraint and checking whether it has moved — keeps improvement priorities aligned with current reality.
