Where a country programme can help.
- Agenda: a cross-ministry risk register that shows which risks have a policy owner.
- Formulation: options dialogues with evidence briefs.
- Adoption: none; decisions are national.
- Implementation: clinics with delivery agencies.
- Evaluation: independent review against stated objectives.

Process
National applications: Policy question to decision
A priority becomes a question, evidence, a decision case and a limited publication; the competent authority decides, never the programme.
01 Question
- 01A priority becomes a questionStep · Universe; national counterpartsA priority becomes a researchable question with stated criteria. National counterparts own the agenda, data and decisions.
- 03Scientific and stakeholder challengeStep · the Global Centre for Risk and Innovation (GCRI); the Global Risks Forum (GRF)Scientific and affected-stakeholder challenge informs mission selection and methods.
02 Evidence and options
- 04Assemble the evidenceStep · GCRIMethods, labelled data and uncertainty are assembled. Every finding carries one of nine evidence labels.
- 06Decision case with optionsRecord · The decision owner named in the caseA decision case binds owner, alternatives, evidence and deadline. It needs sensitivity and robustness.
03 Review and publication
- 07G6 · Publication authorisedGate · The Global Risks ForumGRF authorises publication of results that have passed scientific and editorial review. It cannot publish personal data.
- 08Publish with method, uncertainty and limitsRecord · ReportsFindings are published with their method, uncertainty and limits. An edition is published after review, not to a calendar.
04 Outside the programme
- 02Competent authority decidesDecision · The competent authorityThe authority or institution decides under its own rules. The authority decides; the programme informs.
- 05Action and implementation stay with the ownersActor · The relevant government, operator or licensed institutionDecisions and execution stay with the relevant government, operator or licensed institution. The programme records one only if shared.
05 Learning
- 09Corrections and lessons feed the next agendaStep · UniverseCorrections and lessons feed the next annual agenda. The findings of one year set the mandate of the next.
The Nexus cycle · Decision rights · The programme yearDesigned programme process, not a record of operation. No cycle has run and every programme is at service level R0. A gate is a programme decision, never a public-authority approval, certification or deployment authorisation.
Work is shown as its record stands.
Programmes are listed as exploring, forming, constituted, active, paused or archived. Country and regional entries appear when a programme record supports them.
