Jacob doesn't work here at Grafana Labs anymore unfortunately, but it's nice to know he's still keeping tabs on us and likes what we're up to :)
You should probably ask him to remove the Grafana employment reference/email from his Github profile then.
It seems like this is a special case of project management software. If the existing products can't handle incidents then that software should be improved, not new software written. It's the best way to ensure that everybody on the team knows how to use the software when it's most urgently needed.
E.g. would you change your favorite editor to a different one, in case of an incident? Probably not. So why change project management systems?
Zero here!
You must have solid tech. :)
While you certainly could cobble together incident response workflows in something like Jira, I think it makes more sense to extend the monitoring and paging tooling (in large part due to the reason you mention— familiarity with the tools that you're using as part of that response).
Jira now has OpsGenie so you don’t have to cobble anything together, in theory.
Did we watch a different presentation? ChatOps isn't new. What you're describing is what I would consider an antiquated practice. Nobody wants to go sniffing around a PM tool at 3AM in the morning.
