If we start looking at things broader we will see that there are many things that many need specific attention. Taking into account that Design and UX is more then just Web or mobile App UI. What I mean is for example industrial designers not only design visual aesthetics, also they calculate manufacturing cost, how easy it is to manufacture this product, they study market , how to present innovative product to the market .

Of course modern work trends are into multidisciplinary fields — Swiss nice workers. However as all markets and fields grew then specialisations emerges — UX researcher, UX designer, UI designer, UI developer, Digital Marketing etc.. It is almost impossible to become proficient in all of those fields at the same time. I would say that having general understanding of all process form UX research to sales can tremendously help for company operations. I see different problem here — not Designer but Mangment. There are a lot of medium rank managers in corps that see departments as isolated unites not meant to communicate with others, let alone be intereste fields outside of department “expertise”. Isolation can be real problem not Design.
