"It's good to have domain experts test the usability. But, you don't want lots of bug reports which attempt to make that part of the product do what that particular tester happens to like best. They must ALWAYS take the customer's point of view in their testing.

Also, while the testers may indeed be expert in their area (we hope!), they may miss the big picture, too.

"I think that usability testing is a sub-specialty that often is not best left to the "average tester". Only some (well-trained) testers are capable of doing a really good job of this."

Got something to add?
