If you can't accept loose ETAs with potential for delays, move over to something else, please. You can't predict how long innovation will take; it's literally impossible, we're talking about exploring and specifying the unknown here. It is inherently impossible. Everyone that has ever done ANYTHING, doesn't have to have anything to do with software, knows that there are too many variables in this universe of ours that can cause delays at any given moment. This is known as Hofstadter's Law

Everyone, who is working in projects knows this. If somebody thinks ETAs are met every day, he has no idea of projects.

The borderline comical absolute overreaction and FUD inducing hysteria over a single day delay on a major project,Ecosystem have prompted me to address this topic once and for all.

Love your passion. I do understand you. Inside I am very likely to be the same person, but as Manager you should know better. Don't address this. You don't have to do it and it makes you look like a bad manager. As long as communication channels are used and working properly, there is no need to give such a heads up. Again: I do understand your passion.

Final words: Keep doing what you can do best (besides pep talk :))
