A question-driven executive leadership guide built around one hundred essential CEO questions. Vo Van Thanh Nghia examines four dimensions of enterprise leadership-character, capability, knowledge, and experience-and helps chief executives, founders, successors, directors, and senior leaders confront the decisions and behaviors that shape organizational performance. Each question includes why it matters, an executive standard, warning signs, a practical action, evidence to review, reflection prompts, and a self-assessment. The book also provides a CEO scorecard, decision brief, strategy template, leadership-team review, stakeholder and risk maps, succession tools, crisis planning, a CEO dashboard, and a complete 30-day action plan.
