Revision with unchanged content. Strategy: arguably one of the most abstract elements that leaders have to deal with. But where did it come from and how will it develop in the future? That is the framework within which this book will take a closer look at the phenomenon "strategy". Development tendencies in the field of strategy are found and possible future trends are extrapolated. A historical overview is created to map out the roots of strategy, found in military thinking. The focus is then shifted to strategy in the business environment. An analysis is made identifying the general development trends in the field of strategy. This includes a closer look at two essential phenomena: globalization as well as alliances and networking. The analysis is used as a basis to extrapolate what business strategy will be about in the future. This general forecast includes basic implications and suggestions for companies on how to prepare for the future. The book offers basic research along with practically relevant insights, incorporating content for both, those interested in the historical evolution of strategy, military or business wise, as well as decision makers looking for a new perspective on the topic of strategy.
