This dude is extremely persistent about having irrelevant things his way, and when he doesn’t get it, he acts as if it were a personal attack. Do you guys have any argument or method to deal with this kind of people?
I used to say “whatever” and let him have things his way, but as I got more experienced I started to listen more to his arguments and basically respond “this makes no sense” (not with those exact words, of course).
As a PO if I heard my Dev team wasting valuable time like this, I would put an immediate stop to this.
Not your problem, escalate to management for inefficiency.
As a manager in software engineering: this! If I learned that one of my devs was wasting time like this, I’d want to know. Just make sure to stick to the facts.
