Why does the arrow only go to PagerDuty and not from it? I imagine there's already integrations that initiate an incident via PD so it could be managed from this system. Going only to PD means it has to be managed downstream, recreated in the system or migrate all integrations from PD to an intermediary which seems unwise as it's another failure point. With the arrows the way they are, I would think that this is more of an incident filtering and initiator than management with a people-perspective. My memory's fuzzy but I recall something like that for SNMP traps, maybe called NetView.
