When you hire a Product Owner, you likely do so because this person is well-versed in a wide range of disciplines; they understand some front- and backend coding, timing, budget, business value, analytics, management, etc. In many ways, this is how you should be thinking about hiring Product Designers. Sure, they might have a beautiful portfolio, but can they be a key player throughout the entire product development process? A good Product Designer knows a bit of animation, prototyping, coding, research, visual and interaction design. They know when to deliver wireframes, and when to deliver pixel perfect mockups. They know when to use animation, and when to prototype. They know how to convincingly communicate their solutions.
