3.2. Internal and External Factors

💡 First Principle: The four dimensions don't operate in a vacuum — external forces the organization can't control press on all of them — so ITIL names those forces (PESTLE) to make sure they're considered rather than ignored.

Why care: an organization that perfects its four dimensions while ignoring a looming regulation or market shift is optimizing inside a box that's about to change shape. External factors are the box. The mental model: the four dimensions are inside the organization's influence; PESTLE factors are outside it but constantly shaping what's possible.

⚠️ Common Misconception: That PESTLE factors are internal concerns to be managed directly. They're external — the organization adapts to them but cannot control them.
