 # Support for Experiment, Beta, and Generally Available features
 
+There are cases where GitLab would like to validate the edge-cases of scale, support, and maintenance burden of features in their current form for every designed use case.
+There are also scenarios where a feature is not complete enough to be considered an [MVC](https://handbook.gitlab.com/handbook/product/product-principles/#the-minimal-viable-change-mvc).
+In these cases, GitLab has the option to release features as Experiment, Beta, or Limited Availability, and users can opt-in and test the new experience.
+Features might not be fully documented or supported in the Experiment or Beta phases.
+
+Please note that some features may not be aligned to these recommendations if they were developed before the recommendations were in place or if the group determined an alternative implementation approach was needed.
+
+Product development teams should refrain from making changes that they reasonably believe could create significant risks or friction for GitLab users or the platform, such as:
+
+- Risking damage or exfiltration of existing production data accessed by our users.
+- Destabilizing other parts of the application.
+- Introducing friction into high monthly active user (MAU) areas.

+All features that are available on GitLab.com are considered "in production".
 Because all Experiment, Beta, and Generally Available features are available on GitLab.com, they are all considered to be in production.
+
+## Experiment, Beta and Limited Availability Exit Criteria
+
+To ensure the phases before General Availability are as short as possible each phase of Experiment, Beta and LA should include exit criteria.
+This encourages rapid iteration and reduces [cycle time](https://handbook.gitlab.com/handbook/values/#reduce-cycle-time).
+GitLab Product Managers will take the following into account when deciding what exit criteria to apply to their Experimental, Beta, and Limited Availability features:
+
+- **Time**: Define an end date at which point the feature will be General Availability.
+  - Consider setting a time-bound target metric that will define readiness for exit into GA (e.g. X number of customers retained MoM over 6 months after launch of Experiment, X% growth of free and paid users in three months since launch Beta, etc.)
+  - Be mindful of balancing time to market, user experience, and richness of experience. Some Beta programs have lasted 1 milestone while other have lasted a couple of years.
+- **Feedback**: Define the minimum number of customers that have been onboarded and interviewed.
+  - Consider also setting a time bound when using user feedback as an exit criteria for leaving a phases. If a given time period elapses and we can not solicit feedback from enough users, it is better to ship what we have and iterate on it as a GA at that point rather than maintain a pre-GA state.
+- **Limited Feature Completion**: Determine if there is functionality that should be completed before moving to General Availability.
+  - Be wary of including "just one more" feature. Iteration will be easier and more effective with more feedback from more users so getting to General Availability is preferred.
+- **System Performance metrics**: Determine the criteria that the platform has shown before being ready for General Availability. Examples include response times and successfully handling a number of requests per second.
+- **Success criteria**: Not all features may reach GA. It is OK to pivot if early feedback indicates that a different direction would provide more value or a better user experience. If open questions must be answered to decide if the feature is worth putting in the product, list and answer those.
+
+For the exit criteria of **AI features**, in addition to the above, see the [UX maturity requirements](https://handbook.gitlab.com/handbook/product/ai/ux-maturity/).
