From the LA Times:
The president elect comes to the job with the habits of an entrepreneur and a showman, not a manager of large organization. He's known for making decisions based on the last advice he heard. He makes policy pronouncements on Twitter, often without his aides knowing in advance.
...
"Trump is further behind on taking control of the bureaucracy than any President in history."
...
"Trump has never dealt with a bureaucracy like this," Light said. "His businesses are flat, and that's fine. But the federal government is arguably the least flat organization there is; it has 63 layers of executives and managers."
