I don't know about anyone else, but contrary to my general disdain for meetings* I have found product owners/process managers to be useful in the regard of having one central person to funnel things through on a particular project. The bottleneck also creates a nice buffer of accountability in both directions and they typically offer either new or refined SOPs after solving the same problems over and over again. Plus, they can sit in on the meeting while I go do something useful.

I may just have been lucky with the few I've had to work with though, so your mileage may vary.

*or as the song says, a little less conversation, a little more action please
