What is the difference between takt time and cycle time?

Takt time is the required pace of production based on customer demand — it tells you how fast you need to produce. Cycle time is the actual time it takes to complete one unit at a station. Ideally, cycle time should be equal to or slightly less than takt time.

What happens when cycle time exceeds takt time?

When a station's cycle time exceeds takt time, it becomes a bottleneck. The station cannot keep up with demand, causing delays, WIP buildup, and potential line stoppages. Solutions include redistributing work elements, adding resources, or improving the process.

Does takt time change?

Yes. Takt time changes whenever customer demand or available production time changes. Seasonal demand fluctuations, new product launches, or changes in shift patterns all affect takt time. Production lines must be rebalanced when takt time changes significantly.

How does Yamazo VAS help with takt time analysis?

Yamazo VAS measures actual cycle times from video analysis and displays them against the takt time reference line on Yamazumi charts. This visual comparison immediately shows which stations exceed takt time and by how much, enabling data-driven line balancing decisions.

What is Takt Time? | Definition, Formula & Calculation

Takt time is the rate at which a finished product must be completed to meet customer demand. It is calculated by dividing the available production time by the customer demand in that period. Takt time sets the pace or 'heartbeat' for the entire production line and is fundamental to balancing work across stations.

How to Create

To calculate takt time: (1) Determine the available production time per shift (e.g., 480 minutes minus 30 minutes for breaks = 450 minutes). (2) Determine the customer demand per shift (e.g., 450 units). (3) Divide: Takt Time = 450 min / 450 units = 1 minute per unit = 60 seconds. (4) Use this as the target cycle time for each workstation. (5) Compare actual cycle times against takt time to identify bottlenecks and balancing opportunities. Tools like Yamazo VAS measure actual cycle times from video and overlay them against the takt time on Yamazumi charts.

Example

A factory produces car door panels. The daily demand is 400 units and the available production time is 460 minutes (8 hours minus 20 minutes of planned downtime). Takt time = 460 / 400 = 1.15 minutes = 69 seconds. This means one door panel must be completed every 69 seconds. If Station 4 has a measured cycle time of 82 seconds, it is a bottleneck that needs to be addressed through work redistribution or process improvement.
