Make a deliberate effort to cultivate empathy for other team functions and be able to explain your designs to whoever it is you’re talking to, in their terms. It’s ok to use design jargon as long as you’re able to educate others on what the impressive-sounding words you use actually mean. Break down how your designs fit into the context of what they do and/or company goals. This requires you to get inside the mind of people in a variety of functions and gain a basic understanding and appreciation of what they do and can manifest itself in many ways.
The original (excellent) article talks about lessons for designers. But this part about communication applies everywhere.
