I appreciate what the authors of this book seem to be attempting to do with trying to simplifying approaches and tools for enterprise development when you can. I look forward to reading it. However, my management has bought tools that buy into the heavyweight approach and dont seem to trust the open source and lighter approaches basically because the tools they bought dont support them well out of the box. They dont want to spend money on tools that end up not being used as advetised and (in their minds) waste time and money while I learn the open source or how to integrate them into their tools. Any comments from the authors?
