Seth Godin has an interesting take on the organizational chart. I like the ones describing Microsoft and Apple. I assume Steven Jobs is the red dot in the Apple chart.
The Microsoft one is particularly telling because it has each unit pointing guns at the other units within Microsft! The Oracle one shows way more lawyers than engineers.
In many organizations, instead of arrows showing connections, you might actually include barbed-wire fences and moats between units. In other units, you might show open doors or even no boxes at all.
So, what's your organizational chart look like? More importantly, how does it really work? Instead of arrows and lines, how would you draw your organization and then your unit within the organization?
The actual way an organizational chart works is not a function of its legal formation. It is a result of the leader's style and what he or she allows or not to happen between individuals and units. What atmosphere are you creating with your leadership style?
