Cross-disciplinary teams are becoming more common. Nowadays having exclusive teams with only designers, strategists, coders, researchers, etc working together is very unusual. Nevertheless, in the origin of the identified problem, is that people from different backgrounds and with skill sets have a narrow focus of their roles and tasks, having trouble to communicate and collaborate with people from different silos.
Understanding this is essential for modern organisations if they want to grow and adjust to the current dynamic and fast changing markets.
