+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).)
## How the stages are measured
-Value Stream Analytics uses start events and stop events to measure the time that an Issue or MR spends in each stage.
-For example, a stage might start when one label is added to an issue, and end when another label is added.
-Items are not included in the stage time calculation if they have not reached the stop event.

+For example, a stage might start when one label is added to an issue and end when another label is added.
+Items aren't included in the stage time calculation if they have not reached the stop event.
-| **Stage** | **Description** |
-| --------- | --------------- |
-| Issue | Measures the median time between creating an issue and taking action to solve it, by either labeling it or adding it to a milestone, whichever comes first. The label is tracked only if it already includes an [Issue Board list](../project/issue_board.md) created for it. |
-| Plan | Measures the median time between the action you took for the previous stage, and pushing the first commit to the branch. That first branch commit triggers the separation between **Plan** and **Code**, and at least one of the commits in the branch must include the related issue number (such as `#42`). If the issue number is *not* included in a commit, that data is not included in the measurement time of the stage. |
-| Code | Measures the median time between pushing a first commit (previous stage) and creating a merge request (MR). The process is tracked with the [issue closing pattern](../project/issues/managing_issues.md#closing-issues-automatically) in the description of the merge request. For example, if the issue is closed with `Closes #xxx`, it's assumed that `xxx` is issue number for the merge request). If there is no closing pattern, the start time is set to the create time of the first commit. |
-| Test | Essentially the start to finish time for all pipelines. Measures the median time to run the entire pipeline for that project. Related to the time required by GitLab CI/CD to run every job for the commits pushed to that merge request, as defined in the previous stage. |
-| Review | Measures the median time taken to review merge requests with a closing issue pattern, from creation to merge. |
-| Staging | Measures the median time between merging the merge request (with a closing issue pattern) to the first deployment to a [production environment](#how-the-production-environment-is-identified). Data not collected without a production environment. |
