Hi, I’m David S. Chang – an author, award‑winning entrepreneur, senior technology leader at a Fortune 200 company, and military intelligence Colonel with nearly 25 years of experience.
I’ve led in some of the world’s most complex environments — from combat zones and crisis operations to startups, corporate boardrooms, and the public arena. Over the years, I’ve commanded organizations of 1,600+ people, built companies from the ground up, and managed billions in deal flow. I also write for national publications and speak regularly on leadership, strategy, technology, and decision‑making.
Across all these experiences, I discovered that success or failure isn’t determined by intelligence, talent, luck, or creativity. The most important skill is decision‑making — the ability to think clearly and act decisively under pressure.
Drawing on U.S. Army battle‑tested processes, visual thinking, and cognitive science, I created Decision‑Makership™ — a practical system that helps people master the art and science of decision-making in half the time.
Decision‑Makership™ is built on four foundational laws — the essential principles that guide how we think, choose, and act.
The FOUR LAWS OF DECISION-MAKERSHIP™
LAW I — SMARTER MINDSET
See clearly. Think clearly. Choose clearly.
LAW II — SMARTER APPROACH
Structure the problem. Shape the path. Set the conditions.
LAW III — SMARTER TOOLS
Equip yourself with the right systems, methods, and aids.
LAW IV — SMARTER EXECUTION
Act decisively. Adjust quickly. Finish cleanly.
