Exploratory scenario development
Drivers are mapped, critical uncertainties chosen and combined into a small set of divergent, internally consistent narratives, then challenged by participants from outside the commissioning institution.
GRF · Foresight Nexus
Scenario design and stress testing are the core methods of this platform: building plausible, divergent futures and using them to test whether strategies, plans and institutions hold. In foresight the weight falls on design choices, on who takes part, and on how results reach a decision-holder with a mandate to act.
Scenario design and stress testing construct plausible, severe future conditions to examine how システム and institutions would perform. They complement probabilistic analysis where data are scarce or futures are deeply uncertain. In foresight and risk management and システミック・リスク, stress tests reveal vulnerabilities that arise when several risks materialise together. They inform capital, contingency and coordination plans across sectors. The canonical description is on STEM コモンズ.
Drivers are mapped, critical uncertainties chosen and combined into a small set of divergent, internally consistent narratives, then challenged by participants from outside the commissioning institution.
A strategy or proposed regulation is tested against each scenario in a structured workshop, recording where it fails, what would need to change and which signposts would show that future arriving.
Severe but plausible scenarios are drafted for supervisory exercises or national risk assessments, with the severity reasoning, the assumptions and the institutional responses they test documented.

6 本の柱を通じて、Nexus Consortium が主導
Scenarios are reviewed for plausibility, internal consistency and severity relative to history. Exercise outcomes are compared with actual events when they occur.
| 確認 | 実施方法 |
|---|---|
| Internal consistency | A cross-impact or consistency matrix confirms that the elements of each scenario can coexist |
| Divergence and coverage | The set is checked to span futures that would call for different responses, not variants of one future |
| Challenge by outsiders | Participants from outside the commissioning institution review the assumptions before the set is used |
| 遡及的レビュー | As events unfold, the set is compared with what happened to learn what it missed |
Scenario choice can reflect prevailing assumptions and miss novel combinations. Results depend on how participants and models represent responses.
