3.1.2. Why Each Dimension Matters
💡 First Principle: Each dimension matters because it owns a category of risk no other dimension covers — so understanding what each protects against is more useful than memorizing labels.
What each dimension safeguards: organizations and people ensures the right roles, skills, and culture exist — without it, even good technology is misused or resisted. Information and technology ensures the data and tools are fit and secure — without it, decisions are made blind. Partners and suppliers ensures external dependencies are managed — without it, a supplier's failure becomes your outage. Value streams and processes ensures work is organized to actually produce value — without it, effort is busy but unproductive.
⚠️ Exam Trap: Don't reduce "organizations and people" to just "the org chart." It includes culture, skills, competencies, and ways people communicate — the human system, not just the structure.
Reflection Question: A service has great technology and skilled people but a supplier that misses deadlines. Which dimension is failing, and why can't the others compensate?
