What is cycle time in manufacturing?

Cycle time is the average time required to produce one unit, measured from the start of one unit to the start of the next (or from start to completion of a single unit). It captures all time spent in the process including value-added work, waiting, and transport.

How is cycle time different from takt time?

Takt time is the target production rate set by customer demand (available time divided by units demanded). Cycle time is the actual rate at which the process produces. If cycle time is greater than takt time, the process cannot meet demand. If it is less, there is capacity slack.

What is throughput rate?

Throughput rate is the number of units produced per unit of time, typically expressed as units per hour. It is the inverse of cycle time: throughput = 1 / cycle time. A higher throughput rate means faster production.

How is process efficiency calculated here?

Process efficiency is computed as (units produced × cycle time) / net available time × 100%. It shows what fraction of available time was spent productively. A score below 85% typically signals significant waste or unplanned downtime.

Should I include breaks and downtime in the observation period?

Include the full clock time of your observation window in the total time field. Use the planned downtime field to subtract scheduled breaks and changeovers, so the efficiency calculation reflects net available time rather than gross time.

What observation period length should I use?

Use at least a full production shift for reliable averages. Shorter windows are useful for spotting transient issues but may not reflect steady-state performance. Longer windows smooth out variation and give more representative cycle times.
