First, sorry for the delay in reply. Second, great question! Yes.
(Wouldn't that be funny if it were my whole answer?)
Communication, especially cross-departmental communication, is definitely something that can be improved. It's been getting better, but there's definitely steps we can take to still make it better. Part of the way to introduce communication is cultural, by encouraging it between groups. More than once this year, I've ended up playing middleman and, lo and behold, once I actually get them talking to each other, the problem is resolved!
I feel like there are some groups that took some major strides to communicate more this year, and I'm hoping that I can continue to encourage that behavior. The more we communicate, the more we all know, and the better we're going to work together!
