Value Stream Analytics

  • Introduced as Cycle Analytics prior to GitLab 12.3 at the project level.
  • Introduced in GitLab Premium 12.3 at the group level.
  • Renamed from Cycle Analytics to Value Stream Analytics in GitLab 12.8.

Value Stream Analytics measures the time spent to go from an idea to production (also known as cycle time) for each of your projects. Value Stream Analytics displays the median time spent in each stage defined in the process.

For information on how to contribute to the development of Value Stream Analytics, see our contributor documentation.

NOTE: Note: Use the cycle_analytics feature flag to enable at the group level.

Value Stream Analytics is useful in order to quickly determine the velocity of a given project. It points to bottlenecks in the development process, enabling management to uncover, triage, and identify the root cause of slowdowns in the software development life cycle.

Value Stream Analytics is tightly coupled with the GitLab flow and calculates a separate median for each stage.


Value Stream Analytics is available:

  • From GitLab 12.9, at the group level via Group > Analytics > Value Stream. (PREMIUM)
  • At the project level via Project > Value Stream Analytics.

There are seven stages that are tracked as part of the Value Stream Analytics calculations.

  • Issue (Tracker)
    • Time to schedule an issue (by milestone or by adding it to an issue board)
  • Plan (Board)
    • Time to first commit
  • Code (IDE)
    • Time to create a merge request
  • Test (CI)
    • Time it takes GitLab CI/CD to test your code
  • Review (Merge Request/MR)
    • Time spent on code review
  • Staging (Continuous Deployment)
    • Time between merging and deploying to production
  • Total (Total)
    • Total lifecycle time. That is, the velocity of the project or team. Previously known as Production.

Date ranges

Introduced in GitLab 12.4.

GitLab provides the ability to filter analytics based on a date range. To filter results:

  1. Select a group.
  2. Optionally select a project.
  3. Select a date range using the available date pickers.

How the data is measured

Value Stream Analytics records cycle time and data based on the project issues with the exception of the staging and total stages, where only data deployed to production are measured.

Specifically, if your CI is not set up and you have not defined a production or production/* environment, then you will not have any data for this stage.

Each stage of Value Stream Analytics is further described in the table below.

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, whatever comes first. The label will be tracked only if it already has an Issue Board list 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. The very first commit of the branch is the one that triggers the separation between Plan and Code, and at least one of the commits in the branch needs to contain the related issue number (e.g., #42). If none of the commits in the branch mention the related issue number, it is not considered to the measurement time of the stage.
Code Measures 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 to 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 issue closing pattern is not present in the merge request description, the MR is not considered to the measurement time of the stage.
Test Measures the median time to run the entire pipeline for that project. It's related to the time GitLab CI takes to run every job for the commits pushed to that merge request defined in the previous stage. It is basically the start->finish time for all pipelines.
Review Measures the median time taken to review the merge request that has a closing issue pattern, between its creation and until it's merged.
Staging Measures the median time between merging the merge request with a closing issue pattern until the very first deployment to production. It's tracked by the environment set to production or matching production/* (case-sensitive, Production won't work) in your GitLab CI configuration. If there isn't a production environment, this is not tracked.
Total The sum of all time (medians) taken to run the entire process, from issue creation to deploying the code to production. Previously known as Production.

How this works, behind the scenes:

  1. Issues and merge requests are grouped together in pairs, such that for each <issue, merge request> pair, the merge request has the issue closing pattern for the corresponding issue. All other issues and merge requests are not considered.
  2. Then the <issue, merge request> pairs are filtered out by last XX days (specified by the UI - default is 90 days). So it prohibits these pairs from being considered.
  3. For the remaining <issue, merge request> pairs, we check the information that we need for the stages, like issue creation date, merge request merge time, etc.

To sum up, anything that doesn't follow GitLab flow will not be tracked and the Value Stream Analytics dashboard will not present any data for:

  • Merge requests that do not close an issue.
  • Issues not labeled with a label present in the Issue Board or for issues not assigned a milestone.
  • Staging and production stages, if the project has no production or production/* environment.

Example workflow

Below is a simple fictional workflow of a single cycle that happens in a single day passing through all seven stages. Note that if a stage does not have a start and a stop mark, it is not measured and hence not calculated in the median time. It is assumed that milestones are created and CI for testing and setting environments is configured.

  1. Issue is created at 09:00 (start of Issue stage).
  2. Issue is added to a milestone at 11:00 (stop of Issue stage / start of Plan stage).
  3. Start working on the issue, create a branch locally and make one commit at 12:00.
  4. Make a second commit to the branch which mentions the issue number at 12.30 (stop of Plan stage / start of Code stage).
  5. Push branch and create a merge request that contains the issue closing pattern in its description at 14:00 (stop of Code stage / start of Test and Review stages).
  6. The CI starts running your scripts defined in .gitlab-ci.yml and takes 5min (stop of Test stage).
  7. Review merge request, ensure that everything is OK and merge the merge request at 19:00. (stop of Review stage / start of Staging stage).
  8. Now that the merge request is merged, a deployment to the production environment starts and finishes at 19:30 (stop of Staging stage).
  9. The cycle completes and the sum of the median times of the previous stages is recorded to the Total stage. That is the time between creating an issue and deploying its relevant merge request to production.

From the above example you can conclude the time it took each stage to complete as long as their total time:

  • Issue: 2h (11:00 - 09:00)
  • Plan: 1h (12:00 - 11:00)
  • Code: 2h (14:00 - 12:00)
  • Test: 5min
  • Review: 5h (19:00 - 14:00)
  • Staging: 30min (19:30 - 19:00)
  • Total: Since this stage measures the sum of median time of all previous stages, we cannot calculate it if we don't know the status of the stages before. In case this is the very first cycle that is run in the project, then the Total time is 10h 30min (19:30 - 09:00)

A few notes:

  • In the above example we demonstrated that it doesn't matter if your first commit doesn't mention the issue number, you can do this later in any commit of the branch you are working on.
  • You can see that the Test stage is not calculated to the overall time of the cycle since it is included in the Review process (every MR should be tested).
  • The example above was just one cycle of the seven stages. Add multiple cycles, calculate their median time and the result is what the dashboard of Value Stream Analytics is showing.

Customizable Value Stream Analytics

The default stages are designed to work straight out of the box, but they might not be suitable for all teams. Different teams use different approaches to building software, so some teams might want to customize their Value Stream Analytics. From GitLab 12.9, users can hide default stages and create custom stages that align better to their development workflow.

Adding a stage

In the following example we're creating a new stage that measures and tracks issues from creation time until they are closed.

  1. Navigate to your group page.
  2. Open Value Stream Analytics from the sidebar: Analytics > Value Stream
  3. Click the "Add a stage" button.
  4. Fill in the new stage form:
    • Name: Issue start to finish
    • Start event: Issue created
    • End event: Issue closed
  5. Click the "Add stage" button.

New Value Stream Analytics Stage

The new stage is persisted and it will always show up on the value stream analytics page for your group. In case you want to alter or delete the stage you can easily do that for customized stages by hovering over the stage and clicking the three-dot icon that appears.

Value Stream Analytics Stages

Creating a custom stage requires specifying two events, a start and an end. Be careful to choose a start event that occurs before your end event. For example, consider if a stage started when an issue is added to a board, and ended when the issue is created. This stage would not work because the end event has already happened when the start event occurs. To prevent such invalid stages, the form prohibits incompatible start and end events. After you select the start event, the stop event dropdown will only list the compatible events.

Note: The ability to re-order the stages is a planned enhancement.

Label based stages

The pre-defined start and end events can cover many use cases involving both issues and merge requests. For supporting more complex workflows, we can use stages based on group labels. These events are based on labels being added/removed. In particular, scoped labels are useful for complex workflows.

In this example we'd like to measure more accurate code review times. The workflow is the following:

  • When the code review starts, the reviewer adds workflow::code_review_start label to the merge request.
  • When the code review is finished, the reviewer adds workflow::code_review_complete label to the merge request.

Creating a new stage called "Code Review":

New Label Based Value Stream Analytics Stage

Hiding unused stages

Sometimes certain default stages are not relevant to a team. In this case you can easily hide stages so they no longer appear in the list. First, add a custom stage to activate customizability. Then hover over the default stage you want to hide, click the three-dot icon that appears and select "Hide stage".

To recover a default stage that was previously hidden:

  1. Click "Add a stage" button.
  2. In the top right corner open the "Recover hidden stage" dropdown.
  3. Select a stage.

Days to completion chart

Introduced in GitLab 12.6.

This chart visually depicts the total number of days it takes for cycles to be completed.

This chart uses the global page filters for displaying data based on the selected group, projects, and timeframe. In addition, specific stages can be selected from within the chart itself.

Chart median line

Introduced in GitLab 12.7.

The median line on the chart displays data that is offset by the number of days selected. For example, if 30 days worth of data has been selected (for example, 2019-12-16 to 2020-01-15) the median line will represent the previous 30 days worth of data (2019-11-16 to 2019-12-16) as a metric to compare against.

Disabling chart

This chart is enabled by default. If you have a self-managed instance, an administrator can open a Rails console and disable it with the following command:

The current permissions on the Project Value Stream Analytics dashboard are:

  • Public projects - anyone can access.
  • Internal projects - any authenticated user can access.
  • Private projects - any member Guest and above can access.

You can read more about permissions in general.

NOTE: Note: As of GitLab 12.3, the project-level page is deprecated. You should access project-level Value Stream Analytics from Analytics > Value Stream Analytics in the top navigation bar. We will ensure that the same project-level functionality is available to CE users in the new analytics space.
