PSD.12:3 - Forces
| Force | Tension |
|---|
| Coverage and effort | Joint or structural changes can matter, while unrestricted scenario expansion consumes the available time. |
| Stability and truth | Repeated agreement supports only the tested model and region, not the omitted world. |
| Values and evidence | Better information can resolve a fact, while a disputed trade-off needs a value judgement or legitimate collective decision. |
| Flexibility and commitment | Staging can preserve options, while monitoring, lead time, reversibility, and later authority may be unavailable. |
| Information and action | A probe can change a decision, but it also costs time, resources, exposure, and foregone opportunity. |
