Shirley keeps finding problems everywhere, she's not a team player.

Can you explain how finding problems is the opposite of being a team player? How is a team supposed to get things done if there isn't someone to recognize problems?

No I can't. It's just an attitude that I often see from management.

Management is almost never incented to understand defects.

Not only not a team player but Shirley is also a hypocrite. I guarantee there are non-standards based code touching the refractors she demanded at some level.
