Every company has a culture. Most of the time it simply evolves over time. That is to say, it is a default culture. If you are lucky, that default culture will be the one you want, or at least can live with.
A much better strategy is to determine the culture you want and then take specific steps to make it a reality.
But I imagine that you, like any business owner, know it is much easier said than done. How do you get great outcomes and results while also creating an environment people actually want to work in?
