From a 2011 issue of Fortune:
At Apple there's never confusion as to who is responsible for what. In Apple's parlance, a DRI's name (directly responsible individual) always appear on the agenda for a meeting, so that everyone knows who's the right contact for a project.We need one of those from every client. In our kick-off meetings, we establish a key point of contact who is designated to handle all communication. Not only does this streamline discussions, it also reduces confusion or conflicts in design decisions.
It's a simple thing that goes a long way toward a smooth web design process.
