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.

01In brief

The short answer.

Testing in Nexus Universe is how Oceans and Coasts brings work to the annual programme governed by The Global Risks Forum, with its own site at universe.nexus. Its proposed mission theme is coastal flood and port continuity. Selected work is tested under controlled conditions, reviewed and published with its limits; a theme is a proposal, not a confirmed exercise.

03Themes

Mission themes from this field.

  1. 01

    Coastal flood and port continuity

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

04Exercises

Compound-stress exercises designed for ocean and coastal.

Exercise themeWhat it tests
Coastal flood and port continuityWhether a port and its city can keep critical flows running through a surge event on a higher sea level
05How 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.

06Key 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 decisions in response to a scenario.
After-action reviewA structured discussion after an activity of what was planned, what happened, why, and what to change.
