&gt; I&#x27;ve seen a lot of people during my engineering days who just wouldn&#x27;t work under the pressures required to design a system with extremely high reliability.<p>I think the difference is that most engineers understand when high reliability is necessary, even if they can&#x27;t deal with the pressure of implementation. An MBA whose job is to &quot;move the ship faster&quot; simply isn&#x27;t going to understand the distinction between parts of the system that can be thrown together, and parts that absolutely can&#x27;t.<p>Hard to hire the right people when the majority of MBA&#x27;s aren&#x27;t engineering undergrads.
