We _never_ need them. Who's my manager? I know that. Who does my manager report to? I know who my immediate colleagues are. That's it. That is _all_ I need to know. Above that us shop-floor grunts don't give a tinker's damn because beyond those two levels, regardless of whether the chart shows functions rather than names, it's all "executive" willy-waving and who's got the corner office. Cross team co-ordination? That's what my managers are paid for.

This is the only org. chart us grunt programmers need:

Me --> My manager --> My manager's manager --> Oxygen Thieves.

And there are times when $my_managers_manager is a strong candidate for the Oxygen Thief clique.
