Explains ownership of a critical data element
A role with authority over the element's definition, quality and use answers for it; a team name or a mailbox is not an owner (BCBS 239 Principle 1; DMBOK2 ch. 13, 2.3).
Can AI do this?
AI does this well Most of the tested AI models master this. 4 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 91% | Mastered |
| gemini-3.5-flash-lite | Low cost | 91% | Mastered |
| gpt-6-luna | Low cost | 91% | Mastered |
| claude-haiku-5-5 | Low cost | 91% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: A role with authority over the element's definition, quality and use answers for it; a team name or a mailbox is not an owner (BCBS 239 Principle 1; DMBOK2 ch. 13, 2.3).
