With contributions from some of the field’s most influential scholars, this Handbook provides a path forward for students and researchers interested in strategy process research from a middle management perspective. This groundbreaking Handbook both reviews existing theory and explores new ground concerning key issues surrounding middle management’s influence on strategy making.Split into five distinct sections, the book explicates the unit of analysis and presents foundational theories, emerging models, cutting-edge methods, and original empirical research in strategy process research. Contributors with diverse theoretical and methodological perspectives identify and address a wide range of research issues relevant to middle managers’ participation in strategy making, such as social network analysis and video methodology. Standout chapters include one on complex strategic integration by Robert A. Burgelman and one on development of theory by Henry Mintzberg. This Handbook is a must-read for academics interested in strategy process research as it suggests novel research approaches for addressing relevant phenomena and provides an up-to-date review of the extant literature in the area.
