If you don't know where you are going, you will probably end up somewhere else. ~Lawrence J. PeterI think that too often this is the case. Zappos however has a very clear vision of what they want their culture to be, and they are willing to pay people to quit in order to keep it that way.
I don't think it's a coincidence that the companies that know what they want and pay to get it and keep it that way are the ones that are the most successful. Google, Zappos, and Southwest are a few examples.
It's not as important what you want the culture to be as having that vision and sharing it, preaching it, evangelizing it, and hiring, firing, and encouraging the employees in every way possible to meet that culture.
Do you know what your company culture is? What is it worth?
