Leading with Strategy articulates a bold vision for how strategy must evolve in an era of accelerating uncertainty and complexity. At its core, the book introduces:

• FLUX as the successor to VUCA — moving from the language of volatility, uncertainty, complexity, and ambiguity to a more dynamic paradigm (Fast, Liquid, Uncharted, Experiential) that better captures the lived reality of the 21st-century leader.
• A Strategy Operating System — a practical, integrative framework combining North Star clarity, micro-strategy cycles, paradox mindset, systems thinking, and culture/behavior alignment so organizations can continuously adapt, learn, and execute.
• A holistic philosophy about how strategy is evolving — that strategy must become a living, conscious system, not a static plan; that leaders must see interconnections (between purpose, people, tech, and change); and that the future belongs to those who lead with both rigor and human wisdom.

The book bridges rigorous research, real-world case studies, and actionable tools, designed to help leaders navigate complexity while cultivating coherence, adaptability, and foresight.
