' the book represents a compelling and important work. The theoretical perspective it offers to the academic field of information systems is a refreshing challenge in a literature that has been too heavily populated by unambitious analyses of small problems using narrow frameworks. While the text is aggressive in scope - as indeed it must be, considering the problems it entertains - it is not diffuse. The ideas in it are drawn tightly together by a strong and consistent logical thread .the book should certainly grace the shelves of all researchers with genuine interest in information technology innovation and organizational transformation.'
