-**Lead time**: Median time from issue created to issue closed.
-**Cycle time**: Median time from first commit to issue closed. (You can associate a commit with an issue by [crosslinking in the commit message](../project/issues/crosslinking_issues.md#from-commit-messages).)
-**Lead Time for Changes**: median duration between merge request merge and deployment to a production environment for all MRs deployed in the given time period. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/340150) in GitLab 14.5 (Ultimate only).
## Deployment metrics (**PREMIUM**)
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/337256) in GitLab 11.3.
Value Stream Analytics exposes two deployment related metrics near the top of the page:
-**Deploys:** The number of successful deployments in the date range.
-**Deployment Frequency:** The average number of successful deployments.
The deployment metrics calculation uses the same method as the
[group-level Value Stream Analytics](../group/value_stream_analytics/index.md#how-metrics-are-measured).
Both of them are based on the [DORA API](../../api/dora/metrics.md#devops-research-and-assessment-dora-key-metrics-api).
