In an era of AI, automation, cyber risk, and brittle infrastructure, technical excellence isn't enough. The real challenge is deciding what to build-and how to lead-when the stakes are human. The Integrity Compass: Leading with Ethics in a Changing World is a practical, readable guide to ethical decision-making for engineers, technologists, managers, policymakers, and students navigating complexity and pressure. Blending lived experience with clear frameworks, it shows how integrity becomes action-especially when deadlines, incentives, and power dynamics push the other way. Rather than treating ethics as abstract philosophy, this book gives you tools you can actually use: how to map risk, identify stakeholders, test assumptions, and spot the "quiet" choices that become tomorrow's headlines. Along the way, you'll learn from real-world case studies and deeply human dilemmas-moments in classrooms, boardrooms, and high-stakes settings where people must choose between convenience and courage. A standout section features letters to practitioners based on real situations in medicine, cybersecurity, innovation, and leadership-bringing you into the emotional reality of decisions that can affect safety, trust, and wellbeing. Inside you'll find: * Practical frameworks for ethical decision-making in fast-changing environments * Guidance for building an ethical culture inside teams and organizations * Case studies and lessons from technology, infrastructure, and public trust If you've ever wondered, "What's the right thing to do-when it's complicated?" this book is your compass.
