If we give a value of 1 to very remote dialogue, and 10 to very intimate dialogue, we can place a mark where we feel personally comfortable most of the time. We'll slide up or down a little depending on the situation, but for most of us it doesn't vary that much. Male executive tend to hover around 3, when they meet as a group, the number drops to about 1.5. Female executives, destined to become the saviours of many male-dominated teams, usually behave at a higher level. No executive team will lead an organization to their near future if the level of connection is somewhere on the remote side of 3.
Intimacy means that the corporate secrets have to be exposed.
This can be scary territory. One common secret is that an inner circle of the executive team knows something that the others do not. The only way past this is to talk openly about how the whole group should handle sensitive information and why is that the whole group isn't trusted. Another issue could be that there has been long-standing tension between two team members that never gets discussed openly. Yet another difficult corporate secret to expose is what people in the organization think about the senior executive team performance, including individual team members.
