What Is Cycle Time?
Cycle time measures how long it takes to complete one unit of work from start to finish. Learn why it matters and how to reduce it.
Key Takeaways
- Cycle time is the total elapsed time from the start to the end of a process for one unit of work.
- Shorter cycle times mean faster delivery, lower work-in-progress, and more responsive operations.
- Cycle time includes both active work time and waiting time, making it a comprehensive efficiency measure.
Definition and formula
Cycle time is the total time from when work begins on a unit to when it is complete. If a bakery starts mixing dough at 6 AM and the finished loaf comes out at 9 AM, the cycle time is three hours. This includes active work like mixing and baking, plus any waiting time between steps. Cycle time equals net production time divided by the number of units produced.
Cycle time vs lead time vs takt time
Lead time is measured from the customer's perspective: the time between placing an order and receiving the product. Cycle time is measured from the operation's perspective: how long one unit takes to process. Takt time is the pace at which you need to produce to meet demand. If cycle time exceeds takt time, you cannot keep up with customer orders.
Why reducing cycle time matters
Shorter cycle times mean customers receive orders faster, less capital is tied up in work-in-progress, and problems surface sooner. A Nigerian garment factory that reduces cycle time from five days to three can fulfil more orders per month with the same equipment and staff, directly increasing revenue capacity without adding cost.
How to reduce cycle time
Map every step in your process and categorise each as value-adding or non-value-adding. Eliminate or reduce waiting, rework, unnecessary approvals, and redundant handling. Batch sizes often drive cycle time up; processing smaller batches more frequently usually reduces it. Measure cycle time consistently and track the trend over weeks and months.
