Đông Rùa Theory.

Classical financial analysis treats a company as a closed system: the numbers tell you how the machine inside is running. But your company doesn't live in a closed system. Đông Rùa Theory widens that classical frame with two governance-layer factors: pressure from the outside, and the resilience of the organization itself. Two companies with identical numbers can hold up very differently.

I built this framework over twenty years of building, investing and diagnosing companies in Vietnam's digital economy. It's the backbone of every engagement: separating symptoms from root causes, locating which layer the real problem lives in, and measuring whether today's results will last.
