Doing the right thing is important, which is where strategy comes in. But doing that thing well—execution—is what sets companies apart. After all, every football play is designed to go for a huge gain. The reason it doesn’t is because of execution—people drop balls, miss blocks, go to the wrong place, and so forth. So, success depends on execution—on the ability to get things done.

Business school graduates from the best schools earn large salaries and frequently rise to positions of great power. It would be nice if they used that power to truly make the world a better place - which entails more than just maximizing their own organization's profits and their own economic well-being.

Most organisations say they want creativity, but really they do not.

Great strategy, not executed, can't possibly have any effect on performance because it doesn't actually affect anything. It's like planning for a successful surgery to remove a tumor. If no one picks up the knife and actually operates effectively, the diseases will persist.

People tell me the Netflix series, House of Cards, is sort of like my class come to life. The movie Margin Call portrays the realities of hierarchical relationships and rivalries beautifully, and how people respond when under pressure. Gandhi and Long Walk to Freedom both have the virtue of presenting larger-than-life figures in a more realistic way, showing their flaws and contradictions - their humanity - in a way that is very helpful.

I completely reject the idea that working adults need to be treated like infants or worse and not told the realities, harsh or not, about the world of work. Keeping people in the dark and filling them with stories that are either mostly fabricated, unusually rare, or both, doesn't do anyone any good. It is one of the reasons that workplaces and careers remain in such dire straits.

While it is almost certainly true that leaders ought to eat last, the evidence on the ever-widening difference between CEO and average employee pay and the enormous severance packages leaders obtain even as front-line workers see their economic well-being eviscerated makes a mockery of the idea that leaders do anything other than take care of themselves.
