Mine vs. Ours

When you start a start-up and then hopefully, eventually hire employees, it's critical to have a culture of ownership.  Stock options, of course are a key part of creating this reality but it's not the only ingredient.

Another critical part, among others, is instilling the mind-set and the perspective with your fellow employees and especially key hires - that the company isn't just the founders but "theirs" as well. 

This is done by behavior and actions, primarily, through sharing decision making ("being" collaborative") and generally staying clear of encroaching on your team members delagated authority and responsibility.

I believe, therefore that on the spectrum of "mine vs. ours", it's wrong to be too far to the "mine" side of the scale.  This is depicted by the red zone - on the lower left of the axis.

But what of the other end of the spectrum.  Is it possible to go too far?  Is there an "ours" red zone?
