When we describe GitLab analytics, we use the following terms:
-**Cycle time:** The duration of only the execution work alone. Often displayed in combination with "lead time," which is longer. GitLab measures cycle time from issue first merge request creation to issue close. This approach underestimates lead time because merge request creation is always later than commit time. GitLab displays cycle time in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md).
-**Deploys:** The total number of successful deployments to production in the given time frame (across all applicable projects). GitLab displays deploys in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md).

This effectively measures how often you are delivering value to end users. A higher deployment
frequency means you are able to get feedback and iterate more quickly in delivering
improvements and features faster. GitLab measures this as the number of deployments to a
[production environment](../../ci/environments/index.md#deployment-tier-of-environments) in
the given time period.

## How metrics are measured
The "Time" metrics near the top of the page are measured as follows:
-**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).)
-**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).)
The "Recent Activity" metrics near the top of the page are measured as follows:
-**New Issues:** the number of issues created in the date range.
-**Deploys:** the number of deployments to production (1) in the date range.
-**Deployment Frequency:** the average number of deployments to production (1) per day in the date range.
(1) To give a more accurate representation of deployments that actually completed successfully,
the calculation for these two metrics changed in GitLab 13.9 from using the time a deployment was
created to the time a deployment finished. If you were referencing this metric prior to 13.9, please
keep this slight change in mind.
You can learn more about these metrics in our [analytics definitions](../../analytics/index.md).
