Decision-rights and interface mapping
Each decision is decomposed into the roles that decide, recommend, are consulted and are informed, and each interface between bodies is recorded with its information flow, so failure points become visible.
GRF · Governance Nexus
Systems engineering treats an institution as a system of roles, interfaces and controls. In governance work it traces how authority, information and assurance flow, where failures propagate between bodies, and whether controls are designed and verified to perform the function the governing body relies on.
Systems engineering is an interdisciplinary approach to designing and managing complex systems over their life cycle. It focuses on requirements, interfaces and interactions so that the whole performs as intended. In governance and institutions and risk management and systemic risk, systems engineering exposes interfaces where failures propagate between components and organisations. It supports designing interconnected infrastructure with explicit dependency management. The canonical description is on the STEM Commons.
Each decision is decomposed into the roles that decide, recommend, are consulted and are informed, and each interface between bodies is recorded with its information flow, so failure points become visible.
Controls are specified as requirements and mapped to the Three Lines Model, each traced to evidence from testing, inspection or audit rather than to policy statements.
Fault trees and dependency models trace how a failure in one institution, such as a missed escalation, propagates to others, and where a control would interrupt it.

Each requirement is traced to verification evidence from analysis, inspection, demonstration or test. Independent reviews check completeness at life cycle gates.
| Check | How it is done |
|---|---|
| Traceability | Each control is traced to the risk it addresses and to the evidence that it works |
| Interface review | Every interface between bodies is checked for an owner, a defined information flow and an escalation route |
| Incident reconstruction | Past failures are replayed through the model to test whether it would have shown the failure path |
| Independent review | Control designs are reviewed by someone outside the team that built them |
Emergent behaviour in open or socio-technical systems may not be captured by requirements. Rigid processes can slow adaptation to change.
Three families of instruments side by side against the baseline, each with its own lag and adoption speed, under the coverage and compliance you set; effect sizes are teaching values to replace with evidence. Scenario: named assumptions about the future, not a forecast. The map on this page shows Asia; the model itself is not tied to a place.

The model runs on the teaching values set by the controls. To calibrate it for a place, read it against these admitted layers and series, which this page's map can draw:
Across the six pillars, led by Nexus Consortium

Across the six pillars, led by Nexus Consortium
Systems Science and Modelling stewards systems engineering for the Consortium and reviews how it is applied across platforms.
Assembled from the Nexus Standards area profile Political and governance risk standards: the hazards it names, the systems and communities that carry the loss, the controls and institutions that dampen it and the data that observe it. Pick an initiating event and step through the cascade to see where mandates meet and which decisions fall to whom. The Map view places the run on an example geography with open data. Every weight is a stated assumption. An exercise for dialogue, not a forecast, an assessment or a position. To model a place of your own choosing, open the full System Builder.
