Porter was obviously discussed in Kiechell's book "The Lords of Strategy" and Porter's "What is Strategy" article was a key document in that book showing how Porter helped to guide the Strategy discussion later in his career. It is a short read but very dense in content on what strategy is and probably more importantly what it is not to defend off much of the Johnny come lately works out there on Strategy. Key concept in this work was that it isn't strategy unless it defines how you are going to break out of the pack doing some aspect differently then the rest in a defendable way that drives business value. Porter makes the argument that is is better to forge a new market niche even if in a new industry then trying to fight on the slippery slope of the also rans fighting in an un defendable cut throat market.
