"Organizational change and innovation are central and enduring issues in management theory and practice. The need to understand processes of organization change and innovation has never been greater in order to respond to dramatic changes in population demographics, technology, stakeholder needs, competitive survival, and social, economic, and environmental, health and sustainability concerns. These concerns call for a better understanding of managing organization change and innovation. Why and what organizations change is generally well known; how organizations change is therefore the central focus of this Handbook. It focuses on processes of change, or the sequence of events in which organizational characteristics and activities change and develop over time, and the factors that influence these processes, with the organization as the central unit of analysis. Across the diverse and wide-ranging contributions, three central questions evolve: what is the nature of change and process?; what are the key concepts and models for understanding organization change and innovation?; and how should we study change and innovation? This Handbook presents critical evolving scholarship and explores its implications for future research and practice on organizational change and innovation"--
