##  Lifecycle
Lifecycle shows the various stages an application goes through during its existence. These phases help you track when an application is under consideration, when it's introduced, actively used, replaced or decommissioned, and finally retired from the IT landscape.
Key lifecycle phases:
  * Plan: The application is being evaluated or prepared for introduction.
  * Phase In: The application is being deployed or rolled out.
  * Active: The application is live and in regular operation.
  * Phase Out: The application is being replaced or gradually decommissioned.
  * End of Life: The application is fully retired and no longer in use.
