(This came to me from a VP of HR - Steve)

Our company has had a very traditional hierarchy over time. Most communication, decision-making, and interactions happen from the top down. It hasn't worked and isn't sustainable.

When I've tried to build relationships across functions and departments, I've had limited success. Are there any good examples of how we could start building these? 

I'd love to hear book, blog, or podcast suggestions. If you know a company that made the switch from a top/down organization into a more collaborative one, I'd like to connect with them as well.

Thanks for any feedback or insight you can share.
