# Value stream analytics for projects **(FREE)**

> - Introduced as cycle analytics prior to GitLab 12.3 at the project level.
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12077) in GitLab Premium 12.3 at the group level.
> - [Renamed](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/23427) from cycle analytics to value stream analytics in GitLab 12.8.

Value stream analytics provides metrics about each stage of your software development process.

Use value stream analytics to identify:

- The amount of time it takes to go from an idea to production.
- The velocity of a given project.
- Bottlenecks in the development process.
- Factors that cause your software development lifecycle to slow down.

Value stream analytics is also available for [groups](../group/value_stream_analytics).

      - In the **To** field, select an end date.

The **Lead Time for Changes** metrics display below the **Filter results** text box.

## View number of successful deployments **(PREMIUM)**

To view deployment metrics, you must have a
[production environment configured](../../ci/environments/index.md#deployment-tier-of-environments).

Value stream analytics shows the following deployment metrics for your project:  

- Deploys: The number of successful deployments in the date range.
- Deployment Frequency: The average number of successful deployments per day in the date range.

To view deployment metrics for your project:

1. On the top bar, select **Menu > Projects** and find your project.
1. On the left sidebar, select **Analytics > Value stream**.
1. Optional. Filter the results:
   1. Select the **Filter results** text box.
   1. Select a parameter.
   1. Select a value or enter text to refine the results.
   1. To adjust the date range:
      - In the **From** field, select a start date.
      - In the **To** field, select an end date.

The **Deploys** and **Deployment Frequency** metrics display below the **Filter results** text box.

Deployment metrics are calculated based on data from the
[DORA API](../../api/dora/metrics.md#devops-research-and-assessment-dora-key-metrics-api).

NOTE:
In GitLab 13.9 and later, metrics are calculated based on when the deployment was finished.
In GitLab 13.8 and earlier, metrics are calculated based on when the deployment was created.

## Access permissions for value stream analytics

Access permissions for value stream analytics depend on the project type.

| Project type | Permissions                            |
|--------------|----------------------------------------|
| Public       | Anyone can access.                     |
| Internal     | Any authenticated user can access.     |
| Private      | Any member Guest and above can access. |

## How value stream analytics measures each stage

Value stream analytics uses start and end events to measure the time that an issue or merge request
spends in each stage.

For example, a stage might start when a user adds a label to an issue, and ends when they add another label.
Items aren't included in the stage time calculation if they have not reached the end event.

| Stage   | Measurement method   |
|---------|----------------------|
| Issue   | The median time between creating an issue and taking action to solve it, by either labeling it or adding it to a milestone. The label is tracked only if it already includes an [issue board list](../project/issue_board.md) that has been created for the label. |
| Plan    | The median time between the action you took for the previous stage, and when you push the first commit to the branch. The first branch commit triggers the transition from **Plan** to **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    | The median time between pushing a first commit (previous stage) and creating a merge request. 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`, `xxx` is the 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    | The time from start to finish 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  | The median time taken to review merge requests with a closing issue pattern, from creation to merge. |
| Staging | The median time between merging the merge request (with a closing issue pattern) to the first deployment to a [production environment](../../ci/environments/index.md#deployment-tier-of-environments). Data is not collected without a production environment. |

## Example workflow

This example shows a workflow through all seven stages in one day. In this
example, milestones have been created and CI for testing and setting environments is configured.

- 09:00: Create issue. **Issue** stage starts.
- 11:00: Add issue to a milestone, start work on the issue, and create a branch locally.
**Issue** stage stops and **Plan** stage starts.
- 12:00: Make the first commit.
- 12:30: Make the second commit to the branch that mentions the issue number. **Plan** stage stops and **Code** stage starts.
- 14:00: Push branch and create a merge request that contains the [issue closing pattern](../project/issues/managing_issues.md#closing-issues-automatically). **Code** stage stops and **Test** and **Review** stages start.
- The CI takes 5 minutes to run scripts defined in [`.gitlab-ci.yml`](../../ci/yaml/index.md).
**Test** stage stops.
- Review merge request.
- 19:00: Merge the merge request. **Review** stage stops and **Staging** stage starts.
- 19:30: Deployment to the `production` environment starts and finishes. **Staging** stops.

Value stream analytics records the following times for each stage:

- **Issue**: 09:00 to 11:00: 2 hrs
- **Plan**: 11:00 to 12:00: 1 hr
- **Code**: 12:00 to 14:00: 2 hrs
- **Test**: 5 minutes
- **Review**: 14:00 to 19:00: 5 hrs
- **Staging**: 19:00 to 19:30: 30 minutes

There are some additional considerations for this example:

- Although this example specifies the issue number in a later commit, the process
still collects analytics data for the issue.
- The time required in the **Test** stage is included in the **Review** process,
as every merge request should be tested.
- This example illustrates only one cycle of multiple stages. The value
stream analytics dashboard shows the calculated median elapsed time for these issues.
- Value stream analytics identifies production environments based on the
[deployment tier of environments](../../ci/environments/index.md#deployment-tier-of-environments).
