A portion of the following video demos a custom solution for automating Service outage from a depended CI outage (38.25 min mark). A fully developed CSDM may not be enough. They have a feature to capture whether an outage of one or more related CIs causes an outage to the Service. That mapping is used to automatically create an outage on the Service when an outage on a related CI is created. This mapping could get very complex to cover various scenarios.
