I was recently a testimony of the clash existing between UX Designers and Frontend Developers within a same company. Each team, compromising about 10 to 20 employees each, mocked the other team's work. You know, in the line of "This UX people, spending hours to decide if a pixel goes here or here" or "Frontend guys don't know about creativity, we're always limited with their patterns."
In order to make more efficient design and development cycles those confronted feelings should be addressed. What are the common interests and bridges that can connect the gap between each other's conflicting needs?
