This book examines some of the themes that currently concern both organizations as a science as well as the firm as a dynamic behavioural entity. As we enter a new century, virtually all informed participants and observers of the contemporary organizational scene agree that big changes are underway. This book describes the many and varied changes including increasing inter-dependence, weakening of nation-state boundaries, the rate of technical change, increasing reliance on knowledge systems and workers, the emergence of new forms and changing ties between workers and firms.
