I am hiring three designers. Each will have the same obligations and produce the same work. should I hire one of them as Art Director to have some sort of hierarchy, or the three can be Art Directors because they will work in separate projects?
"Art Director" can me a number of different things:
- senior graphic designer
- graphic design manager
- artistic lead
- client liaison
And, often, some combination of the above.
As such, we simply can't answer this question for you without understanding the context of your company and your department's current needs.
