Your <i>In a perfect enterprise</i> line carries the implication that no companies are like what he described.  But I've worked in multiple companies that worked like this.<p>Just because your company doesn't do this doesn't mean that others don't.<p>As for your silly example, you're pushing enforced openness.  But people, even in the most open companies, sometimes need to be closed.  However if the company is working well then people have no problem reaching out to IT early.<p>Incidentally in my last job there indeed was a woman who was part of IT but sat in on another department's internal meetings, saw figures, etc.  She took on that role after the previous project manager left.  Said project manager was from that department but was managing several IT people.  Either way IT and the other department are integrated together.
