Books are just pieces of paper. They only add value when read by a person and add even more value discussed as by a group of people and add substantially more value when discussed by a group of highly competent people with experience.<p>Anyone gifted with vision and a brain can do the first option, it's even somewhat easy to do the second, but the third is really hard to pull off. HBS provides this at staggering cost (plus credentialing and a network) but surely someone can figure out how to replicate the case experience much more easily?
