Круто сказано про Портера
“Porters Five Forces model is simple. It is nothing but microeconomics. This man had locked himself in a library for a few years, had analyzed some companies and than he managed to summarize nearly the whole science of microeconomics in one single simple model. – That is the reason why all other economists hate him: they are envious because they did not see something so obvious themselves.”
