7  Why This Framework Exists

This cluster addresses a foundational question: why do conventional analytical approaches fail for long-horizon infrastructure decisions, and what conditions make a different framework necessary?

The sections here establish the intellectual terrain — the philosophical roots of decision analysis under deep uncertainty, the seven requirements that any defensible decision support environment must satisfy, and the formal mathematical foundations that underpin the evaluative standards of regret, robustness, and satisficing used throughout the framework.

Readers already fluent in DMDU methodology can read the seven requirements and mathematical notation and proceed directly to Part II.
