title: Feature Lifecycle

|

Feature lifecycle is currently in beta
|

|
||
|
||
|
||
In Unleash, the feature lifecycle encompasses a holistic view of how mature your feature is based on data collected through metrics and interactions with the Unleash system.
|
||
As such, the lifecycle mirrors your software development process and allows you to identify bottlenecks at any stage of the lifecycle.
|
||
These findings may give you insights or clues to improve the efficiency of your software development process. Read more about how Unleash progresses a feature through the lifecycle below.
|
||
|
||
## Lifecycle stages
|
||
|
||
Each stage in the lifecycle has a defined purpose:
|
||
|
||
### Initial stage
|
||
|
||
The feature flag is created but remains unseen in any environment.
|
||
|
||
**Purpose:** marks the initiation of the feature.
|
||
|
||
### Pre-live stage
|
||
|
||
The feature flag has received metrics in non-production environment or has received metrics in a disabled production environment.
|
||
|
||
**Purpose:** testing and validating the feature before it goes live.
|
||
|
||
### Live stage
|
||
|
||
The feature has received metrics in the enabled production environment.
|
||
Once enough has been learned about the feature from production usage, you can mark the feature as completed.
|
||
When marking a feature as complete, you decide whether to keep the feature, discard it, or keep one variant of the feature.
|
||
This information can be used by code cleanup tools to automate feature removal from your code.
|
||
|
||
**Purpose:** testing and validating the feature in production and marking feature completion.
|
||
|
||
### Completed stage
|
||
|
||
The feature's objectives have been achieved, and it is ready to be phased out.
|
||
The lifecycle feature warns you if a completed feature continues to receive traffic, signaling that it hasn't been fully removed from the code.
|
||
If you've accidentally marked the feature as completed, you can always revert it to the live stage.
|
||
|
||
**Purpose:** initiating cleanup processes and signalling when it's safe to archive a feature.
|
||
|
||
### Archived stage
|
||
|
||
The feature is archived in Unleash and can be deleted. If an archived feature is revived, it starts a new lifecycle with a new initial stage.
|
||
|
||
**Purpose:** reducing technical debt by removing obsolete features.
|
||
|
||
## Lifecycle stages and process improvement
|
||
|
||
Understanding how much time a feature spends in each stage can highlight inefficiencies:
|
||
* **Stuck in Initial**: May indicate integration issues in pre-production setups.
|
||
* **Stuck in Pre-live**: Suggests challenges in achieving production readiness.
|
||
* **Stuck in Live**: Could imply difficulties in data gathering or decision-making regarding the feature’s future.
|
||
* **Stuck in Completed**: Indicates delays in decommissioning the feature and cleaning up resources.
