In my last post I mentioned “Idea bug”, which I have got a number of questions about. I have taken the term from the GTAC 2011 Opening Keynote – Test is Dead (a good video, by the way). If you go approx 17:00 into the video, the presenter defines it as:

Code bug:
Wrong product behavior


Idea bug:
Wrong product!

Hope it is clear why we want to avoid idea bugs Smile
