Energy projects shape the modern world. They power economies. They influence global human development. Yet behind every project is a single force: the quality of its decisions. Good decisions-not simply good resources or even good forecasts-drive long?term value creation. This applies to all projects, and especially to the uncertain and complex world of energy.

This book introduces a decision analytic and market?based approach to project assessment. It blends the craft of assessment with economic logic and strategic insight. It explains how to frame decisions, evaluate alternatives, and model uncertainty, to reveal the hidden value of flexibility and information. Above all, it shows how clear thinking can create positive impact in an uncertain world. Good decisions build better projects-and ultimately, better futures.
