NXS-DSS
NXS-DSS (decision cases and deliberation) supports decisions with evidence: scenarios, options, trade-offs and their uncertainty, prepared so that a competent authority can deliberate and decide.

03The problem it addresses
Options compared on one scenario look better than they are.
NXS-DSS is defined in system profile NRS-S3 of the Nexus Standards. Investment and policy choices about systemic risk are made under deep uncertainty. Decision support has to compare options across many plausible futures, show what each assumes, and leave the value judgements to the people accountable for them.
- Scenario sets with stated assumptions.
- Options assessed for robustness, not only expected value.
- Deliberation records and handoff to the deciding body.
04Reference practice
The standards a design like this is read against.
| Reference | Relevance |
|---|---|
| ISO 31000 risk treatment | Selecting and justifying treatment options |
| IEC 31010 | Techniques including decision-tree, multi-criteria and scenario analysis |
| IPCC AR6 Working Group II | Adaptation pathways and decision-making under uncertainty |
05Neighbouring systems
What it exchanges with the other systems.
- Reads indicators and risk products from NXS-GRX (canonical data, provenance and risk).
- Hands decisions to records in NXS-RLS (participants, agreements and handoffs).
06Rooms
The ten rooms of NXS-DSS.
NXS-DSS has the eight rooms every Foundry system shares, set to its own authority, and two specialist rooms, Scenarios and Decisions. Each is described by the work it is designed for; the public register records NXS-DSS as declared, not deployed.
| Room | Kind | Designed to |
|---|---|---|
| Station | Shared | Operate, inspect and correct authoritative domain posture for decision support, scenarios, options, trade-offs and uncertainty |
| Mission | Shared | Coordinate bounded objective-oriented intelligence and human handoff for decision support, scenarios, options, trade-offs and uncertainty |
| Builder | Shared | Design, engineer and prepare governed changes and artefacts for decision support, scenarios, options, trade-offs and uncertainty |
| Maps | Shared | Inspect and compose spatial, temporal and world-model intelligence for decision support, scenarios, options, trade-offs and uncertainty |
| Data | Shared | Work with data, ontology, Chronotopes, graphs, scientific methods and risk for decision support, scenarios, options, trade-offs and uncertainty |
| Commons | Shared | Work with policy, law, standards, clauses, obligations and assurance for decision support, scenarios, options, trade-offs and uncertainty |
| Reports | Shared | Compute, model, synthesise and visualise governed analytical products and reproducible reports for decision support, scenarios, options, trade-offs and uncertainty |
| Knowledge | Shared | Work with institutional memory, records, citations, runbooks and learning for decision support, scenarios, options, trade-offs and uncertainty |
| Scenarios | Specialist | Let analysts construct reproducible alternative futures and counterfactual cases |
| Decisions | Specialist | Support transparent option appraisal under multiple objectives, constraints, stakeholder preferences and uncertainty |
07Access
Authorised projects only.
Access requires an authorised project with an accountable owner, data terms and a review plan. Enquiries go to the contact form.
08Risk Academy
Where NXS-DSS subjects are taught.
Risk Academy, led by the Nexus Consortium, teaches the subjects practised in NXS-DSS in these disciplines; the Global Centre for Risk and Innovation (GCRI) links to the Academy as a partner and does not provide its courses.
