That's exactly right. There were good and bad things. Some method was needed, but too much method is lethal to productivity. Agile was sold as less rigid method, but for many shops it's simply too much. You need first to make it work, later to make it perform, then to optimize it, finally to trash and replace it. Many go right away to optimize then stall.
