What are the secrets to making a company enduringly valuable? 7 Powers breaks fresh ground by constructing a comprehensive strategy toolset that is easy for you to learn, communicate and quickly apply. Drawing on his decades of experience as a business strategy advisor, active equity investor and Stanford University teacher, Hamilton Helmer develops from first principles a practical theory of Strategy rooted in the notion of Power, those conditions which create the potential for persistent differential returns. Using rich real-world examples, Helmer rigorously characterizes exactly what your business must achieve to create Power. And create Power it must, for without it your business is at risk. He explains why invention always comes first and then develops the Power Progression to enable you to target when your Power must be established: in the Origination, Take-Off or Stability phases of your business. Every business faces a do-or-die strategy moment: a crux directional choice made amidst swirling uncertainty. To get this right you need at your fingertips a real-time strategy compass to discern your true north. 7 Powers is that compass.

The fiftieth anniversary edition of the National Book Award–winning bestseller that is the definitive study of Adolf Hitler, the rise of Nazi Germany, the Holocaust, and World War II. This special edition now features a new introduction by Ron Rosenbaum, author of Explaining Hitler and How the End Begins. No other powerful empire ever bequeathed such mountains of evidence about its birth and destruction as the Third Reich. When the bitter war was over, and before the Nazis could destroy their files, the Allied demand for unconditional surrender produced an almost hour-by-hour record of the nightmare empire built by Adolph Hitler. This record included the testimony of Nazi leaders and of concentration camp inmates, the diaries of officials, transcripts of secret conferences, army orders, private letters—all the vast paperwork behind Hitler's drive to conquer the world. The famed foreign correspondent and historian William L. Shirer, who had watched and reported on the Nazis since 1925, spent five and a half years sifting through this massive documentation. The result is a monumental study that has been widely acclaimed as the definitive record of one of the most frightening chapters in the history of mankind. Here is the complete story of Hitler's empire, one of the most important stories ever told, written by one of the men best equipped to write it. This worldwide bestseller has been acclaimed as the definitive book on Nazi Germany; it is a classic work.
