Teams such as the Australian Cricket Team, FC Bayern Munich, the All Blacks and Williams Formula 1 have all experienced unparalleled success in their sports, maintained year after year even as individuals on the team come and go. In their search for the principles of excellence, the authors analysed the highly effective organizations which carry out the operations behind the scenes which enable the teams to achieve these astonishing levels of success, amassing hard evidence and interviewing key inspirational players, both on and off the field. Icons such as Michael Jordan, Frank Williams, Franz Beckenbauer, Sir Donald Bradman, Sir Peter Blake and Jonah Lomu are among the many figures who assisted them in their research. The result is the elite theory of Peak Performing Organizations (PPO). The authors have identified consistent practices for nurturing peak performance and key techniques which will unlock effectiveness - lessons which can be applied to all business to achieve sustainainable success.
