There is a subtle feature to Yankee Stadium that I would have never noticed had I not gone on the official tour: the ballpark was intentionally constructed to leave a gap that allows the subway cars to be visible.
Spectators don’t consciously think about the presence of the quintessentially New York method of transportation, but the franchise felt it was important for the subway to be incorporated into the plans.
It serves as a good metaphor for culture. Those creating it do so intentionally, but those living it may not explicitly notice its presence. Nevertheless, its existence makes an impression and contributes to the overall environment and character of the place.
Think of what is the equivalent of your “subway gap”. Is there an element of your culture that should be intentionally incorporated into your space? Does what makes you “you” physically show up in your organization? The details become the differentiator.
