(Berlin, Memorial to the Murdered Jews of Europe) – Some weeks ago, when I visited the Memorial, the feeling of loneliness and lack of direction invaded me. I think this is the main achievement of the architect (Peter Eisenman)… bring this feeling to the visitors. And from the position in the picture I asked to myself “What have we learned from this horror?”. Inspired by a continuous learning for a continuous improvement, I would like to make the question applied to bugs and change requirements (CR), but particularly in this post: what can we learn from bugs? We should take them all as improvement opportunities.
