What does "lead time" mean?
Lead time is the time that passes from when a task enters the system to when it is fully completed. In other words, how long the client or customer waits for the result, from the moment of the request to the delivery of value.
Example
If a user submitted a request on March 1 and the task was finished on March 10, then lead time = 9 days. This includes all stages: analysis, waiting, work, testing, and release.
Why measure lead time
- Transparency for the client - shows how long a request actually takes to complete.
- Assessing predictability - a stable lead time means a stable process.
- Finding bottlenecks - a growing lead time signals that tasks are getting stuck somewhere.
- Planning deadlines - helps forecast the completion date of new tasks.
Lead time vs Cycle time
| Metric | Starting point | Shows |
|---|---|---|
| Lead time | When the task appeared in the backlog | How long the client waits for the result |
| Cycle time | When work on the task began | How long the active work takes |
Conclusion
Lead time is a key indicator of the speed of delivering value. The shorter and more stable it is, the faster and more reliably the team meets the client's needs.
