What can responsibly be returned now without taking the choice? | PSDA.11 and the qualified contributing PSDA.5, PSDA.6, PSDA.7, PSDA.8, PSDA.9 results; FPF A.15.9, A.10 and C.11. |
| 14 | PSDA.15 - Arrange Decision Follow-up or Reassess Advice After a Change | Stable | follow-up, observation, interpretation, change. Which relied-on premise changed, and which advice must be reconsidered? | PSDA.14 when recommendation follow-up is live; FPF A.10 for one known reliance; A.10.1 when a changed source requires discovering and revalidating several uses; G.11 for currentness; direct subject or service guidance for its own question. |
