Operations
Capacity & Throughput
Capacity is not the theoretical speed of one machine; it is the sustainable output of the constrained production system.
What this topic covers
What a capacity study should reveal.
Output can be limited by cycle time, uptime, changeovers, staffing, yield, material availability, inspection or downstream flow. Looking only at nameplate rate misses the system constraint.
- Separate demonstrated rate from assumed or theoretical rate.
- Quantify losses that consume available production time or effective output.
- Model the constraint and test whether proposed improvements actually move system capacity.
The useful answer is how much good product the system can reliably deliver—and what truly limits it.
Capacity belongs to the production system—not the fastest machine in it.
When the issue needs execution, bring the operating condition, evidence and constraint.
