When we describe GitLab analytics, we use the following terms:
-**Cycle time:** The duration of your value stream, from start to finish. Often displayed in combination with "lead time." GitLab measures cycle time from issue creation to issue close. GitLab displays cycle time in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md).
-**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).

- All incidents are related to a [production environment](../../ci/environments/index.md#deployment-tier-of-environments).
- Incidents and deployments have a strictly one-to-one relationship (meaning any incident is related to only one production deployment, and any production deployment is related to no more than one incident).
-**Lead time:** The duration of the work itself. For more information, read [Lead time for changes](#lead-time-for-changes). Often displayed in combination with "cycle time." GitLab measures from issue first merge request creation to issue close. This approach under-estimates lead time because merge request creation is always later than commit time. GitLab displays lead time in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md).
-**Lead time:** The duration of your value stream, from start to finish. Different from [Lead time for changes](#lead-time-for-changes). Often displayed in combination with "cycle time," which is shorter. GitLab measures lead time from issue creation to issue close. GitLab displays lead time in[group-level Value Stream Analytics](../group/value_stream_analytics/index.md).
-**MTTC (Mean Time to Change):** The average duration between idea and delivery. GitLab measures MTTC from issue creation to the issue's latest related merge request's deployment to production.
-**MTTD (Mean Time to Detect):** The average duration that a bug goes undetected in production. GitLab measures MTTD from deployment of bug to issue creation.
-**MTTM (Mean Time To Merge):** The average lifespan of a merge request. GitLab measures MTTM from merge request creation to merge request merge (and closed/un-merged merge requests are excluded). For more information, see [Merge Request Analytics](merge_request_analytics.md).
