In this book, strategy expert and Columbia Business School professor Rita McGrath takes on one of most fundamental and recognized notions in strategy: that of sustainable competitive advantage. She argues this can no longer be the Holy Grail for companies because in a constantly changing environment, deeply ingrained structures and systems designed to extract value actually become a liability. The new path to winning includes taking advantage of shorter term opportunities, as well as relying on new organizational talents like speed and decisiveness. McGrath defines the new transient lifecycle of competitive advantage and shows how successful firms manage through it by using an updated philosophy.
