PSD.14:3 - Forces
| Force | Tension |
| Timely warning and observation burden | Frequent data may detect changes sooner, but collection, interpretation and response have costs and can overwhelm the receiving work. |
| Focused learning and unexpected change | A targeted test can resolve a decisive question while overlooking a new concern outside the original model. |
| Continuity and justified revision | Stable advice avoids needless churn; preserving a conclusion after its premise fails creates false confidence. |
| Shared follow-up and differentiated authority | One arrangement connects observers, specialists, advisers and choosers without giving them each other’s powers. |
| Trigger clarity and uncertain evidence | An explicit condition helps action, but a noisy measure or an unqualified threshold cannot decide the response. |
| Service continuity and a bounded engagement | Follow-up may require real client contact or referral while the completed recommendation application remains complete. |
