Change is inherently dangerous. Moreover, change becomes even more dangerous when we don"t know what we"re doing. Attempts to change software organizations commonly fail because of inadequate understanding of change dynamics -- the same reason the organizations got into crisis in the first place. Jerry Weinberg concludes his series of four stand-alone volumes with this pragmatic, comprehensive testament on the fundamentals of change management. From systems thinking to project management to technology transfer to the interaction of culture and process, this volume analyzes change from a broad range of perspectives, spanning the spectrum of sources of organizational change. Such breadth of awareness is essential for successful management of system evolution.
