How the Domain Ontology Readiness Survey gate works
How the Domain Ontology Readiness Survey grades each domain's data model and rolls the portfolio up to its weakest: an entity-scale gate forces UNMODELED on a large domain missing identity rules, so an 88%-mean portfolio still reads NO MODEL.
How the gate works
This tool grades every domain's model against the six things a machine needs to check it, then rolls the portfolio up to its weakest domain. It reads 6 domains and rolls them into one verdict — the worst, never the average — and then a gate that can only make it worse.
The 6 domains
| Domain | Verdict |
|---|---|
| D-01 Billing | UNMODELED28 entity types · both gate levers PARTIAL · gate fired · 83% coverage |
| D-02 Support desk | PARTIALsame marks as D-01 but 6 entity types — under the gate threshold · 83% |
| D-03 Billing (hardened) | MODELEDevery dimension declared · 100% |
| D-04 Inventoryfix first | UNMODELEDidentity rule undeclared · gate quiet · 67% coverage |
| D-05 Product catalog | MODELED41 entity types, fully declared · 100% |
| D-06 Fulfilment | UNMODELED22 entity types · overlap lever PARTIAL · gate fired · 92% coverage |
The verdict bands
A domain with 15 or more entity types whose closed-value-set or disjointness lever is not fully MODELED is forced to UNMODELED however high its coverage — at that size an undeclared value set or overlap is where the contradictions come from. One UNMODELED domain overrides the mean coverage, so the whole portfolio reads NO MODEL.
In the worked sample it reads NO MODEL — Mean coverage across the six domains is 88% and two are fully MODELED — on the average this portfolio looks close. But three domains read UNMODELED: Billing and Fulfilment cross the entity-scale gate with a modeling lever still PARTIAL (at 83% and 92% coverage), and Inventory has an undeclared identity rule with the gate quiet. One UNMODELED domain forces NO MODEL, so the mean decides nothing. The one thing to fix first: D-04 Inventory — 'What makes two records the same thing is defined' is UNMODELED and it is the lowest-coverage domain at 67%. Declare its identity rule first; Billing and Fulfilment then need their gate levers finished..
Common questions
Can every domain look survivable on the How the Domain Ontology Readiness Survey gate works and the company still read NO MODEL?
Yes. The roll-up takes the worst of 6 domains — never the average — then a worsen-only gate, the Entity-scale gate, escalates when trouble clusters. In the worked sample it reads NO MODEL because mean coverage across the six domains is 88% and two are fully MODELED — on the average this portfolio looks close. But three domains read UNMODELED: Billing and Fulfilment cross the entity-scale gate with a modeling lever still PARTIAL (at 83% and 92% coverage), and Inventory has an undeclared identity rule with the gate quiet. One UNMODELED domain forces NO MODEL, so the mean decides nothing.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-set of survivable lines, because a single disqualifying gap shouldn't hide behind an average of the healthy ones. The tool also names the one thing to fix first — here, "D-04 Inventory — 'What makes two records the same thing is defined' is UNMODELED and it is the lowest-coverage domain at 67%. Declare its identity rule first; Billing and Fulfilment then need their gate levers finished.".
Grades a domain model you describe. A working aid, not legal, security, or compliance advice, and not an audit or a certification. It never scores or ranks people — MODEL HOLDS means these six things are written down, not that they are correct.
