A.3.3.PI:4.1 - Specify the future question and the available account
Name the quantity, event or choice being predicted, the horizon and the inputs over that horizon. Specify the accuracy or decision boundary when it changes what information is needed. Predicting a total after one treatment cycle, determining whether it will be below a limit, and estimating a long-run average can require different information.
Recover the rule of change, observation meanings, sampling times and available initial information. Separate uncertainty about the state from uncertainty about the rule or future input. A longer observation history cannot replace an unspecified intervention.
State what the proposed description retains: present readings, model coordinates, past inputs and outputs, derived features or weights over possible states. Where future actions are chosen by a controller, retain the action assumptions needed by the comparison.
