'It is not so very difficult to predict the future. It is only pointless...what is always far more important are fundamental changes that happened though no one predicted them or could possible have predicted them.' (quote taken from this book) It is these unpredictable and irreversible changes from the past, and their effect on the role of the executive which Peter Drucker examines in his latest book. The management of change is a subject which has been, undoubtedly, the principal preoccupation of management thinkers in the 1990s. Peter Drucker, the guru's guru, brings together a group of his own original essays and interviews on this vitally important topic. As ever, he provides invaluable food for thought for all executives and students of business and management.
