Meg Witman is running for governor of California on the premise that she has been successful at establishing a large corporation efficiently and profitably. I think that she is setting herself for one hell of a culture shock.
I would question the capacity for a successful executive to manage a government. My view is that a large corporation starts its slide and loses efficiency in direct proportion to the degree that it begins to act like a government. For said large corporation then, it would follow that an executive is successful in how she prevents that type of culture from developing.
So if there is was to be an executive that I would particularly feel good about voting for would be one who has taken an ossified, hidebound corporation and turning it back into an innovator. For instance, taking Microsoft and developing a consistent slate of products that would generate buzz on the level of Apple.
