Value stream analytics for groups (PREMIUM)
Introduced in GitLab 12.9 for groups.
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.
- Detecting long-running issues or merge requests.
- Factors that cause your software development lifecycle to slow down.
Value stream analytics is also available for projects.

The Deploys and Deployment Frequency metrics display below the Filter results text box.
Deployment metrics are calculated based on data from the DORA 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.
How value stream analytics aggregates data
- Introduced in GitLab 14.5 with a flag named
use_vsa_aggregated_tables
. Disabled by default.- Filter by stop date toggle added in GitLab 14.9
- Data refresh badge added in GitLab 14.9
Plans for value stream analytics to filter items by stop event instead of start event are tracked in this epic. With the completion of this work, value stream analytics will only display items with a stop event in the date range.
To preview this functionality, you can use the Filter by stop date toggle to enable or disable this filter until the default filtering mode is introduced and the toggle is removed.
If you turn on the Filter by stop date toggle, the results show items with a stop event within the date range. When this function is enabled, it may take up to 10 minutes for results to show due to data aggregation. There are occasions when it may take longer than 10 minutes for results to display:
- If this is the first time you are viewing value stream analytics and have not yet created a value stream.
- If the group hierarchy has been re-arranged.
- If there have been bulk updates on issues and merge requests.
To view when the data was most recently updated, in the right corner next to Edit, hover over the Last updated badge. This badge is only available if you have turned on the Filter by start date toggle.
How value stream analytics measures stages
Value stream analytics measures each stage from its start event to its end event.
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.
Value stream analytics allows you to customize your stages based on pre-defined events. To make the configuration easier, GitLab provides a pre-defined list of stages that can be used as a template
Each pre-defined stages of value stream analytics is further described in the table below.
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, whichever comes first. The label is tracked only if it already has an issue board list created for it. |
Plan | The median time between the action you took for the previous stage, and pushing the first commit to the branch. The first commit on the branch triggers the separation between Plan and Code. At least one of the commits in the branch must contain the related issue number (for example, #42 ). If none of the commits in the branch mention the related issue number, it is not considered in the measurement time of the stage. |
Code | The median time between pushing a first commit (previous stage) and creating a merge request (MR) related to that commit. The key to keep the process tracked is to include the issue closing pattern in the description of the merge request. For example, Closes #xxx , where xxx is the number of the issue related to this merge request. If the closing pattern is not present, then the calculation uses the creation time of the first commit in the merge request as the start time. |
Test | The median time to run the entire pipeline for that project. It's related to the time GitLab CI/CD takes to run every job for the commits pushed to that merge request. It is basically the start->finish time for all pipelines. |
Review | The median time taken to review a merge request that has a closing issue pattern, between its creation and until it's merged. |
Staging | The median time between merging a merge request that has a closing issue pattern until the very first deployment to a production environment. If there isn't a production environment, this is not tracked. |
Example workflow
This example shows a workflow through all seven stages in one day.
If a stage does not include a start and a stop time, its data is not included in the median time. In this example, milestones have been created and CI/CD 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. Code stage stops and Test and Review stages start.
- GitLab CI/CD takes 5 minutes to run scripts defined in
.gitlab-ci.yml
. - 19:00: Merge the merge request. Review stage stops and Staging stage starts.
- 19:30: Deployment to the
production
environment 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:
- This example demonstrates that it doesn't matter if your first commit doesn't mention the issue number, you can do this later in any commit on the branch you are working on.
- The Test stage is used in the calculation for the overall time of the cycle. It is included in the Review process, as every MR should be tested.
- This example illustrates only one cycle of the seven stages. The value stream analytics dashboard shows the median time for multiple cycles.
How value stream analytics identifies the production environment
Value stream analytics identifies production environments by looking for project environments with a name matching any of these patterns:
-
prod
orprod/*
-
production
orproduction/*
These patterns are not case-sensitive.
You can change the name of a project environment in your GitLab CI/CD configuration.
Custom value streams
Introduced in GitLab 12.9.
Use custom value streams to create custom stages that align with your own development processes, and hide default stages. The dashboard depicts stages as a horizontal process flow.
Create a value stream
Introduced in GitLab 13.3
A default value stream is readily available for each group. You can create additional value streams based on the different areas of work that you would like to measure.
Once created, a new value stream includes the stages that follow GitLab workflow best practices. You can customize this flow by adding, hiding or re-ordering stages.
To create a value stream:
- On the top bar, select Menu > Groups and find your group.
- On the left sidebar, select Analytics > Value Stream.
- If this is the first time you are creating a value stream, select Create custom value stream. Otherwise, in the top right, select the dropdown list and then Create new Value Stream.
- Enter a name for the new Value Stream.
- You can customize the stages.
- Select Create Value Stream.
NOTE: If you have recently upgraded to GitLab Premium, it can take up to 30 minutes for data to collect and display.
Create a value stream with stages
- Introduced in GitLab 13.7.
- Enabled by default in GitLab 13.10.
- Feature flag removed in GitLab 13.11.
You can create value streams with stages, starting with a default or a blank template. You can add stages as desired.
To create a value stream with stages:
- On the top bar, select Menu > Groups and find your group.
- On the left sidebar, select Analytics > Value Stream.
- If this is the first time you are creating a value stream, select Create custom value stream. Otherwise, in the top right, select the dropdown list and then Create new Value Stream.
- Select either Create from default template or Create from no template.
- Select Create Value Stream.
Label-based stages
The pre-defined start and end events can cover many use cases involving both issues and merge requests.
In more complex workflows, use stages based on group labels. These events are based on added or removed labels. In particular, scoped labels are useful for complex workflows.
In this example, we'd like to measure times for deployment from a staging environment to production. The workflow is the following:
- When the code is deployed to staging, the
workflow::staging
label is added to the merge request. - When the code is deployed to production, the
workflow::production
label is added to the merge request.
Edit a value stream
Introduced in GitLab 13.10.
After you create a value stream, you can customize it to suit your purposes. To edit a value stream:
- On the top bar, select Menu > Groups and find your group.
- On the left sidebar, select Analytics > Value Stream.
- In the top right, select the dropdown list and then select the relevant value stream.
- Next to the value stream dropdown list, select Edit. The edit form is populated with the value stream details.
- Optional:
- Rename the value stream.
- Hide or re-order default stages.
- Remove existing custom stages.
- Add new stages by selecting the 'Add another stage' button
- Select the start and end events for the stage.
- Optional. To undo any modifications, select Restore value stream defaults.
- Select Save Value Stream.
Delete a value stream
Introduced in GitLab 13.4.
To delete a custom value stream:
- On the top bar, select Menu > Groups and find your group.
- On the left sidebar, select Analytics > Value Stream.
- In the top right, select the dropdown list and then select the value stream you would like to delete.
- Select Delete (name of value stream).
- To confirm, select Delete.
View number of days for a cycle to complete
- Introduced in GitLab 12.6.
- Chart median line removed in GitLab 13.4.

- On the top bar, select Menu > Groups and find your group.
- On the left sidebar, select Analytics > Value stream.
- Above the Filter results box, select a stage:
- To view a summary of the cycle time for all stages, select Overview.
- To view the cycle time for specific stage, select a stage.
- Optional. Filter the results:
- Select the Filter results text box.
- Select a parameter.
- Select a value or enter text to refine the results.
- To adjust the date range:
- In the From field, select a start date.
- In the To field, select an end date.
Type of work - Tasks by type chart
Introduced in GitLab 12.10.
This chart shows a cumulative count of issues and merge requests per day.
This chart uses the global page filters for displaying data based on the selected group, projects, and time frame. The chart defaults to showing counts for issues but can be toggled to show data for merge requests and further refined for specific group-level labels.
By default the top group-level labels (max. 10) are pre-selected, with the ability to select up to a total of 15 labels.
