"There are definitely times when the outside eye can shine a light on something you weren't aware of. They're usually exposing a flaw or a problem. Sometimes they're saying, "Hey, this doesn't really work. Have you seen this?" And then, you go, "Oh, I didn't really see that. You're right, that doesn't work." If they're good, they shine a light on issues that you're blind to because you're too close to it."
