Designers are often hesitant to receive feedback on their designs from someone who is not close to the project.
“But they don’t have the context!”
This has always confused me. When I present a design flow, I find the people who are furthest away from the project gave really valuable feedback. They see things I don’t. And if I find myself having to explain things in order to figure out how to interact with my prototype, something is up.
After all, when this ships, the user won’t have been part of any of the project meetings, be aware of the research, any technical constraints, or otherwise. The design and implementation of it will need to stand on its own.
