Penny Cagan has written the operational risk book the industry has been waiting for: authoritative, experience-rich, and unflinchingly relevant. Drawing on nearly four decades in the field, she brings a rare combination of clarity, judgment and lived insight to a discipline that is evolving faster than ever. Whether she is unpacking the complexities of RCSA design and execution or setting today's challenges against the backdrop of pandemics, climate shocks and geopolitical instability, Penny shows practitioners not just what operational risk is, but how to manage it in the real world. --LEWIS O'SULLIVAN, Publishing Consultant; Former Publisher, Risk Books Practical frameworks for navigating operational risk from climate change to cyber threats Managing Operational Risk in a Changing World provides practical frameworks and methodologies for risk professionals facing an evolving discipline. As regulations change and new threats emerge from geopolitical risk, artificial intelligence, cyber attacks, and pandemic scenarios, practitioners need guidance organized around contemporary challenges rather than historical definitions. This book blends nearly 40 years of frontline experience with emerging themes that define today's operational risk landscape. Each chapter integrates the author's direct experience with interviews from industry veterans and case studies ranging from Barings to Silicon Valley Bank. The book demonstrates how risk frameworks can be applied in practice, covering resilience, climate considerations, staffing challenges, and the operational risk implications of AI adoption. Readers gain tools and techniques to implement risk methodologies successfully, supported by perspectives from multiple practitioners rather than a single voice. Written for operational risk professionals, academics, and students in enterprise risk management programs, this book serves as both a practitioner's manual and classroom text. A companion website offers supplementary materials for instructors, making it an essential resource for professional development and academic coursework alike.
