The only interpretation of that I'm coming up with is that each step of the process would be kicked off in Slack.
Wouldn't that mean people could easily stomp on each other's toes? Wouldn't there also be tons of needless noise as each of us does our workflows?
I use Slack daily, but we don't have any automation hooked up in it. I realize some teams drive deploys, alerts, and other stuff through it. That makes sense to me - this does not.
What benefits would that give?
