Mahler and Casamayou make new and creative use of the well-studied NASA case; surface novel insights about NASA as a public organization that enhances our understanding of the subtle and complex organizational and managerial circumstances surrounding these accidents; and extend our conceptual understanding of organizational performance, reform, and change... This is a rich re-analysis of the organizational and managerial context of the Challenger and Columbia accidents... Offers a very worthwhile set of theoretical improvements and practical lessons. Journal of Public Administration Research and Theory [Offers] a well-organized, lucid and informative discussion both of organizational learning theory, and of relevant case details. It provides a well-balanced and evidence-based assessment of factors facilitating or inhibiting organizational learning processes. Moreover, this book is relatively unique in its case-based effort to refine and offer hypotheses relative to existing theory, while simultaneously providing practical insights for managers. The focus on underlying processes related to organizational learning is especially helpful because it renders the framework transferable across various public sector settings or events. Given the range of ongoing public sector concerns in complex and high risk areas such as health pandemics, nuclear proliferation and testing and international relations, this book will have broad relevance and appeal. Management Learning This book deepens our understanding of the complexities of learning processes in the public service context, but it should also be useful to all scholars of organizations and organizational learning for its detailed analysis of the non-learning and unlearning that occurred between the two disasters.
