Why Devs Should Be Involved in Design Reviews

I like being involved in design reviews before a screen feels finished. There are useful questions a developer can bring while changing the design is still inexpensive.

What happens with no results? How does this work with a keyboard? Where does that information come from? Those questions aren't objections to the design. They help us make the version people will actually use, including the states that don't fit neatly in the presentation.
