Organisation charts almost always depict organisations as an equalateral triangle. It is a simple change in perspective, to see it with a third dimension, like the Egyptian pyramid. Suddenly, it is clear that the guts of the organization are largely hidden from view.

It also becomes clear that enterprises can really only work when there is engagement across the third dimension, with all the complication that engagement implies.

This simple act, of thinking about the organisation and how it works including the third dimension is an easy way to recognise the complications inherent in the management processes and decision-making necessary to make the thing effective. Cross functional co-operation then becomes an obvious necessity, not something mandated by someone with a good idea.
