You make great points. Most of which you enumerate, if not all, can be traced back to two fundamental concepts; communication and understanding. Communication because this is how understanding can be propagated and the lack thereof remedied. Understanding because this is fundamental to the success of any endeavour. Without it one or more of the symptoms above will manifest. With it, they may still, but at least there can exist a pathway to success. In my experience, the majority of problems in the software engineering industry are people problems. Not technical, nor technology, nor process problems. This is why communication and understanding are vital to success.
