That email Elon sent asking for better 3Q performance is exhibit A showing how bad Elon's management skills are. In a functional organization, you work with your direct reports, outline the issue (gotta perform in Q3), instruct them to meet the goal, ask if you can help remove impediments to that goal, negotiate what resources they need, give them the negotiated help/resources.
Instead Elon is undercutting his senior mangement team's authority and ability to manage their own organizations by continually interfering with the entire organization. Sleeping on the QA line is laudable from a leadership perspective, but horrible from a management perspective. Why didn't Elon get the head of QA to sleep there? Why isn't he empowering his senior management to act as leaders instead of continually undercutting them?
That email also completely undercuts Elon insistence that Tesla doesn't manage quarter by quarter. It shows he is as much of a slave to quarterly numbers as any maligned CEO in corporate America. The fact that the email says that the Q3 numbers will basically be window dressing for a financing round doesn't help.
