What is Cycle Time?
Cycle Time is the elapsed time from starting a work item to finishing it, including waiting within that interval. Lead Time starts earlier, at the initial request. Compare the two to distinguish time spent before work starts from time spent getting started work to completion.
Formula
Cycle Time = Work Completion Date - Work Start DateLead Time = Delivery Date - Request Date (includes queue time). Cycle Time = Completion Date - Active Work Start Date. The gap between Lead Time and Cycle Time is queue time - how long work waited before anyone started it. Example: Feature requested Monday, work started Wednesday, completed Friday. At the same time of day, Lead Time = 4 elapsed days, Cycle Time = 2 elapsed days, Queue Time = 2 days.
Benchmarks and interpretation
- Compare similar work items measured with the same start and finish points
- Report the median and a high percentile, such as P95, to show both typical completion time and slower cases
- Investigate long waits and blocked work before assigning a cause to rising cycle time
- Agree delivery expectations using your own historical distribution; there is no universal number of days for a good cycle time
When to use Cycle Time
- Diagnosing delivery bottlenecks by comparing cycle time distributions across workflow stages
- Setting SLA commitments for bug fix response times based on historical cycle time data
- Measuring the impact of process improvements such as reducing work-in-progress limits
- Identifying outlier tasks with anomalously long cycle times that need root cause analysis
- Confusing cycle time with lead time and using them interchangeably in reports, which misleads stakeholders about where delays occur
- Measuring cycle time only at the task level and missing stage-level bottlenecks within the workflow
- Targeting average cycle time reduction without also reducing cycle time variance, which matters more for predictability
- Use a cycle time scatterplot (time to complete on Y axis, completion date on X axis) to spot trends and outliers more clearly than averages alone
- Review work-in-progress limits when queues and competing tasks increase cycle time
- Decompose stories into smaller tasks to reduce cycle time and increase delivery frequency without changing team capacity
