What is throughput in manufacturing?

Throughput is the rate at which a system produces completed units over a given time period. It is the inverse of cycle time: if a machine takes 5 seconds per unit, its theoretical throughput is 720 units per hour.

What is the difference between cycle time and takt time?

Cycle time is how long it actually takes to produce one unit. Takt time is the available production time divided by customer demand — it is the pace you need to meet. If your cycle time exceeds takt time you have a bottleneck.

How is utilization calculated?

Utilization = (Available Time − Planned Downtime) / Available Time × 100. It shows what percentage of available time the system is actually running. Unplanned downtime further reduces effective throughput.

What is effective throughput?

Effective throughput = theoretical throughput × utilization. It accounts for scheduled downtime, changeovers, and maintenance windows, giving a realistic production target for planning purposes.

Can I use this for software systems or queues?

Yes. Throughput applies to any system that processes discrete units — transactions, API requests, tasks, or physical parts. Enter the average processing time per unit as the cycle time.
