Tester's Musings

 I find this quite true, from personal experience: I find it more productive when testing with an independent mindset, even when part of a dev team. And actually, everyone appreciates the resulting product evaluation-- positives and negatives included. A strategy where a coder tests his own work plus a test specialist evaluating the end prototype -- doesn't seem superfluous. Each brings a unique contribution to the quality of the end product as a whole.
