Executive failure rarely begins with a single catastrophic decision. More often, it begins with cognitive overload, reactive leadership, compressed timelines, and decision systems that quietly deteriorate under pressure. In Decision Fatigue, leaders will learn why executive decision-making is fundamentally different at the CXO level—and why traditional productivity advice fails in high-consequence environments. Blending behavioral science, governance insight, and enterprise leadership strategy, this book equips executives to reduce cognitive drag, regulate decision pressure, improve judgment quality, and build decision systems that withstand board scrutiny. Because at the highest levels of leadership, the real advantage is not making more decisions. It is designing more defensible ones.
