Good product managers anticipate the serious product flaws and build real solutions. Bad product managers put out fires all day. - Ben Horowitz

There is no such thing as a great executive. There is only a great executive for a specific company at a specific point in time.

In a poor organization, on the other hand, people spend much of their time fighting organizational boundaries, infighting, and broken processes. They are not even clear on what their jobs are, so there is no way to know if they are getting the job done or not. In the miracle case that they work ridiculous hours and get the job done, they have no idea what it means for the company or their careers. To make it all much worse and rub salt in the wound, when they finally work up the courage to tell management how fucked-up their situation is, management denies there is a problem, then defends the status quo, then ignores the problem.

a company needs lots of smart, super-engaged employees who can identify its particular weaknesses and help it improve them.
