Engineering leaders, especially at large companies, are managing a team of a couple hundred people. That team might cost $50 to 100 million in salary a year. So as a CEO, when you hear from your eng leaders that ‘Engineering is an art, and you can’t predict how it’s going to work,’ it’s frustrating. They’re sitting there thinking, ‘They’re telling me this is art, but I’m spending $100 million on this art each year.’ That’s not reassuring.
