Takt time

Takt time is the maximum time allowed to produce one unit in order to meet customer demand. It translates customer pull into a production pace. “Takt” is German for beat or pulse (as in a conductor’s beat) — it sets the rhythm of production.

Formula

Takt time = Available production time ÷ Customer demand rate

Both must use the same time unit (minutes per unit, seconds per unit, etc.)

Worked example

Interpreting takt time vs. cycle time

• Cycle time < takt time: Process is faster than demand. Risk of overproduction or idle time. Rebalance work across steps, reassign people, or run fewer hours rather than build ahead of demand.
• Cycle time = takt time: Process exactly matches demand, with no margin; in practice many plants plan cycle time slightly below takt.
• Cycle time > takt time: Process is a bottleneck — it cannot keep up with demand. This step limits throughput and must be improved.

How takt time guides the Improve phase

In a DMAIC Improve phase, takt time tells the Green Belt the target cycle time for each process step. A value stream map overlaid with takt time immediately shows which steps exceed takt (bottlenecks) and which are well under it (candidates for load balancing or combining). The Improve goal is to bring all steps to at or below takt time without creating overproduction upstream.

Common exam traps

• Using total shift time instead of available time: Deduct breaks, scheduled maintenance, and any planned downtime before dividing by demand.
• Confusing takt time with cycle time: Takt time is a target set by customer demand. Cycle time is the actual time the process takes per unit.
• Takt time changes when demand changes: If demand doubles, takt time halves. Takt time is recalculated for each planning period.
