Does Information Technology matter? This book argues that even as Information Technology hardware, software, data and associated processes are becoming more of a commodity, it has never been more important to manage Information Technology as a strategic asset. However, managing Information Technology as a strategic asset is notoriously difficult, as is studying the impact of Information Technology on firm performance. This book sets out to identify, explain and critically evaluate current research in this area.A unique feature of this book is the use of economic theory to explain management theory and its consequences in professional practice. Beginning with a thorough introduction to Schumpeterian economic theory, the authors re-cast the pre-eminent theory in strategic management research (the Resource Based View) in the light of a Schumpeterian analysis and identify Dynamic Capabilities as an extension of, but also a radical departure from, RBV. The role of Information Technology as an endogenous technology is discussed and it is argued that how we define Information Technology determines not only how we study it but also how we use it and benefit from it.The book is aimed primarily at the academic research market, but should also be of some interest to managers. It is useful more specifically for all those studying business, Information Technology, strategy, management and innovation.
