Takt Time vs Cycle Time
A manufacturing guide explaining the difference between takt time and cycle time, with formulas, examples and a production decision map.
Takt time and cycle time answer different questions. Takt time is the pace required by customer demand. Cycle time is the time the process actually takes to make one unit. The two should be compared, not substituted for one another.
Visual distinction
CUSTOMER DEMAND ↓ AVAILABLE PRODUCTION TIME ↓ TAKT TIME "How often do we need one unit?" ACTUAL PROCESS ↓ CYCLE TIME "How long does one unit take?"
Formula
Takt = net available production time ÷ customer demand. A basic measured cycle time over a representative period can be expressed as elapsed production time divided by units produced.
Example
A cell has 420 minutes of net available time and demand is 210 units:
Takt = 420 / 210 = 2.00 min/unit = 120 sec/unit
If the measured process cycle is 1.6 min/unit, the process itself is faster than the demand pace, subject to quality losses, changeovers, bottlenecks and downstream constraints. If cycle time is 2.6 min/unit, the process is slower than demand pace.
| Relationship | Meaning |
|---|---|
| Cycle < takt | Process pace is faster than demand pace. |
| Cycle = takt | Process pace matches demand pace. |
| Cycle > takt | Process pace is slower than required demand pace. |
Takt is not a machine setting
Takt does not determine RPM or feed. It is a planning metric. Machine parameters still come from tooling, material and process requirements.
Source: Lean Enterprise Institute defines takt time as available production time divided by customer demand. LEI Takt Time.
