Vernon Joyce I think when it comes UX<->dev communication it’s not about the coding knowledge either. I think UX people should be interested in how the technology works in general and why dev use one thing or another, what are APIs and how they are used, rather than actually learn to code (I say this from 10 years of experience as a programmer). And the other way around is what you said: devs should be at least generally interested in how UXers use the design workflow to propose things to be implemented in production.

Both camps should equally take interest in management tasks and goals and the overall business side of the company they work for, but that’s a topic for another story :)
