OPS.15.1:4.6 - Return the quantity to the operating decision

Explain the result in terms the recipient uses: for example, “the machine was occupied for forty of the sixty available minutes” or “the shorter internal time excludes four hours of waiting before admission”.

Retain the definition and observations needed to reproduce a consequential quantity, using the existing account when it suffices. Distinguish a direct calculation from a model-based estimate or forecast. MMP.13 supplies inference when the result must generalize beyond the observed population.

When a check fails, localize the repair: a subject was counted twice, a boundary event was misidentified, a clock was shifted, an unfinished interval was excluded, or the aggregation rule answered another question. Correct that construction and the decisions that used it. A changed route, acceptance event or recording procedure reopens the affected quantity.
