Notifying individuals when certain events occur in the registry is another common use case for design/change time policies. CentraSite includes a built-in email action that you can use for this purpose.

You might, for example, use this action to send an email to key users in your IT organization when a service switches to the Production state of its lifecycle. You might also create custom actions that would send messages to and/or trigger processes on external systems when certain events occur in the CentraSite registry.
