I have a team in my org that uses a single level escalation policy to alert all of their responders. They do this because they are responding to critical alerts that have been escalated by upper level executives and they feel that response time is the most important metric for their team. Unfortunately because of this focus on response time, they have responders duplicating work by acknowledging and working incidents that have already been assigned.
This team is requesting that incidents only allow a single responder for their incidents. I don’t know that that makes sense, but I think a warning pop up when attempting to acknowledge an incident that has already been acknowledged could work. Maybe make one of these an optional setting at the service level?
