This book is about the changes that elected and appointed leaders are making to the art and practice of governing, governance, and government. It is about how public managers are shaping and guiding governments’ responses to a fundamental movement for change that began in the last decades of the twentieth century. The changes taking place over the last two decades in all levels of government have been, in a word, transformational; the administrative model of governance that guided public administrators for more than a century has been turned on its head, to be replaced by a new type of governing by new kinds of public managers (Rhodes 1997)
