Bush’s MBA


Twenty-six of 42 presidents, including Bill Clinton, were lawyers. Seven were generals. George W. Bush becomes the first with an MBA.
Those who have had Bush for a boss since the mid-1980s—in the (1) of oil, baseball and Texas state government—describe his management (2) as straight from the pages of the organizational-behavior (3) he studied while getting his masters of business administration (4) at Harvard University in 1975.
He manages by what is known (5) "walking around," having learned that sitting behind a desk and passing out memos does (6) to energize anyone.
He has a reputation for fueling "creative tension" (7) his subordinates, encouraging them to take and defend opposing (8) .

That’s one trait that might be of concern, says Michael Useem, director of the Wharton Center for Leadership and Change at the University of Pennsylvania. It’s important for subordinates to feel part of the team, but not just because the boss craves popularity. Just as in the military, it must be understood who is in charge when the final order is given.
