01In brief

The short answer.

Testing in Nexus Universe is how Health and Biosecurity Governance brings work to the annual programme governed by The Global Risks Forum, with its own site at universe.nexus. Its proposed mission theme is cross-border health coordination. Selected work is tested under controlled conditions, reviewed and published with its limits; a theme is a proposal, not a confirmed exercise.

Scoping to review.

Canvas · scoping to reviewDesign, not a record
Test in Nexus Universe: an exercise from design to lessonsObjectives and a scenario are designed with the owner; injects are scripted; players respond in cells while controllers and observers watch; a hot wash and an after-action report turn observations into owned improvements. Design of the process, not a record of a run.

03Geography

Environmental exposure in Southern Africa.

For test in nexus universe, in GRF's situational-awareness reading, the map opens on population density and flood water, framed on Southern Africa; 4 further NASA layers wait in the list.

The interactive map needs JavaScript; the layer list and sources are below.

04Themes

Mission themes from this field.

  1. 01

    Cross-border health coordination

    Proposed for controlled testing in the annual programme; a theme is not a confirmed exercise.

05Missions from this field

Exercising coordination, not pathogens.

Planned missions test notification, border measures and cross-ministry decisions in an outbreak scenario. Scenarios are built from public epidemiological parameters at a level that reveals nothing sensitive.

06How testing works

Controlled, reviewed and reversible.

Selected work is tested under controlled conditions, reviewed and then published with its limits. Results that pass go to Nexus Reports. The planned stand-down of each edition keeps review, reconciliation and corrections going after the event.

07Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Mission themeA subject a platform proposes for controlled testing in the annual Nexus Universe programme; a theme is a proposal until the programme confirms an exercise.
Simulation exerciseA practice, training or evaluation activity in which an emergency is described or simulated and participants respond as they would in reality, so that plans and capacities can be tested, as WHO's exercise manual describes.
Tabletop exerciseA discussion-based exercise in which participants talk through their response to a scenario.
After-action reviewA structured review of what was planned, what happened and what should change, held after an exercise or real event.
