Provenance
Every number here, and what re-derives it
This site is not allowed to state a figure it cannot re-derive from the codebase. The build fails if it tries.
That rule has teeth: an earlier draft claimed one product was the only one present in every lifecycle phase, and the check that enforces this refused it — a second product was too. The claim was corrected before anyone outside read it. There are currently 253 such checks across the estate.
| Figure | Derived from | By | Source last changed |
|---|---|---|---|
| 122ontology classes graded against ISBEGO Each grading also records the rule or model that produced it and a confidence level. where it appears | apps/data-domain/seed-data/ontology-class-dimensions.json | apps/site/scripts/gen-isbego.mjs | 2026-07-1824e03871f |

What is deliberately not here
- No outcome percentages. This site used to carry four — 85% less tracing time, 60% faster delivery, 95% better risk identification, 40% fewer overruns. Nothing measured any of them: no engagement, no method, no date. They were removed rather than sourced, because an unattributed percentage is what makes a reader stop believing the rest of the page.
- No uptime SLA and no price list. Neither exists. An availability figure is a contractual commitment, not an adjective.
- No comparison to other tools. We have not run one. The figures above are what this estate contains; what anyone else contains is not ours to state.
