Experts and technical support
Some institutions need an expert or a small team for a defined piece of work. Nexus Agency is the route of The Global Centre for Risk and Innovation (GCRI) for competence-based technical assistance, staffing and expert matching, under explicit terms and mandates. A match is an enquiry route, not an appointment or a contract. Scope, checks and boundaries are below. Part of GCRI programmes.

What expert support covers.
Technical assistance
Bounded capacity-building under a defined scope. See Technical assistance.
Independent review
Senior experts and reviewers for methods, findings and report editions, with declared interests.
Mission teams
Specialists for a mission in the annual programme, with stated prerequisites and supervision.
Scoping to review.
Fig.A programme from scoping to the owner's decision. Design, not a record.
Checks before any assignment.
- 01
Enquiry
The institution describes the work, the counterpart and the authority for the next step.
- 02
Competence
Experts are matched on competence and availability, not on payment or affiliation.
- 03
Conflicts
Interests are declared and checked; a reviewer with a declared conflict never signs the relevant acceptance.
- 04
Terms
A scoped assignment with review criteria, supervision and a contribution record, agreed with the correct parties.

What expert support is not.
- A match is not an appointment, an employment offer or a contract.
- Unqualified contributors never take safety-critical tasks.
- Experts act within the scope of the assignment and hold no authority over the institution's decisions.
- Paid work, internships and fellowships are separate arrangements with their own terms.
Model experts and technical support as a system. Run the cascade.
Assembled from the Nexus Standards area profile Global and systemic risk: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification.
Hazards
- Dam failure
- Financial contagion
- River flood (set off downstream)
- Flash flood (set off downstream)
- Mass displacement (set off downstream)
- Widespread power outage (set off downstream)
- Water supply shortfall (set off downstream)
- Sovereign debt crisis (set off downstream)
- Currency crisis (set off downstream)
Systems and couplings
- Global and systemic risk
- Compound and cascading hazard standards Mechanism
- Financial stability and prudential risk Mechanism
- Supply chain and trade risk Cascade
- Future generations and long-term risk Common driver

Institutions with a defined need, and experts with a defined competence.
Public institutions, national and regional consortiums, programme coordinators and project sponsors describe a need. Senior experts, reviewers, practitioners and technical contributors describe their competence and availability. The Agency is designed to connect the two within a written scope. Both sides then know the task, the supervision, the review criteria and how the assignment ends.
How to reach Nexus Agency.
The current service level is R0: information and enquiries. The Agency platform is at Nexus Agency. Experts write to experts@therisk.global. Institutions seeking support write to the Secretariat at contact@therisk.global. The Global Risk Alliance (GRA) runs separate Professional working groups for finance specialists.
