I agree they can be improved. But they are not one-time activity. It should be a continuous process in order to really be efficient. Also every on-call person needs to be diligent about it. Otherwise, it aggregates in future.

Again, I am talking about the teams who are heavily loaded with alerts and incidences during on-call. In general, all these pain points very much vary depending on the on-call load. We also have a teams who do manage all of these easily as their on-call load is quite manageable. But solving for them in one place so that everyone from the team is on the same would be amazing.
