The architecture questions — who owns the model, what breaks under failure, where data flows, who maintains the AI — don't fit in a slide deck. That's where purchases go wrong. DD makes those questions first-class.
Four qualitative dimensions capture an AI vendor's architectural posture. Each has a defined rubric with fixed values; each links back to public evidence. Shape at right: ServiceNow — an ai-augmented workflow platform with hybrid model ownership and medium dependency risk.
Beyond the categorical dimensions, every profiled vendor gets three 1–10 scores. The three together produce the radar — a shape, not a total. Anthropic at right: high Independence and Sovereignty, deliberately lower Learning Loop because they don't train on customer API calls. That differential is the DD story a single score would hide.
