The first lecture on where CR came from , the business case, and the course outline with links to readable articles is here.
For readers who like this, Mallen Baker and I have put together a complete online training course on all this, with short, interesting videos covering all this and more.
Take a look at it at: http://g2g-training.com
You even get a certificate afterwards. It’s packed with up to date practical business case studies, not theory.
