Designing Organizations: 21st Century Approaches is a benchmark publication in the field of organization design. The recent development in organization design has been sporadic; hence, this book will be an important step in creating more thoughtful research and stronger empirical analyses that take advantage of advances in estimation methods allowing for more complex causal modeling and stimulation technologies. Featured in the book are the more practical elements of implementing OD in organizations. The chapter material is organized into five sections: (1) Putting Contingency Theory in its Place, (2) Focus on Individuals who make up the Organization, (3) Innovation Processes and Organization Design, (4) Adaptation and Technology, and (5) Design for Performance. The book will be a broad discussion of topics in the field, but still each individual chapter will provide in-depth analysis of the topic.
