This was a surprisingy accurate account of the histories of the terms and the philisophies they (originally) described. There is also excellent advice, implicit, if not explicit. Unfortunately, I'm not sure it's broadly meaningful in the current environment where those terms are attached to job titles and/or departments fairly indiscriminantly.
