Methods and critical debate
The methods Policy Nexus relies on to inform policy and governance decisions: comparative governance, policy analysis, foresight and exercises with institutions, with the mandates they serve and their limits.

|---|---|---|
| Cost-benefit and cost-effectiveness analysis | Comparing value of options | Decision analysis |
| Game-theoretic analysis | Strategic behaviour between jurisdictions | Game theory |
| Programme evaluation | Did the policy cause the change? | Causal inference |

Methods and critical debate: Asset register to adaptation
A generic method sketch using standard hazard, exposure and vulnerability vocabulary; no single body publishes this chain, so it is not a standard.
01 Inputs
- 01Asset registerDataset · Policy ownerA register lists the public assets in scope with their location and condition.
- 02Hazard layersDatasetHazard maps, for example flood or heat, come from a named source. The source is set by the page.
02 Analysis
- 03OverlayModelA spatial join places each asset in the hazard zones.
- 04ExposureDatasetExposure lists the assets and people served in the hazard zones.
- 05Vulnerability classesModelVulnerability classes by asset type, for example damage curves, relate hazard intensity to expected damage.
- 06Risk rankingStep · Policy ownerAssets are ranked by expected damage and criticality. The ranking criteria are chosen by the owner.
03 Plan
- 07Adaptation optionsStepOptions such as grey or green measures are listed with their co-benefits and costs.
- 08Capital planDecision · Policy ownerThe responsible body decides which options enter the capital plan.

How uncertainty is reported.
- 01
State assumptions
Each analysis lists its assumptions and the data it depends on.
- 02
Quantify where possible
Ranges and confidence are reported alongside central estimates.
- 03
Validate and compare
Models are checked against observations and, where possible, against other models.
- 04
Publish limits
What an analysis cannot show is stated beside what it can.
