Nope not true. I worked 8+ years managing small to large teams. Doing very little work. And my teams were routinely outcompeting much larger teams. For example, a customer told me that my team of 15 routinely outcompeted a 75 person team at his company. I did it by clearly defining objectives, assigning responsibilities, and getting out of their way. The only key thing I had to do beyond that was to gently remind developers to focus on priority #1 when they got distracted and drifted off track.
