C.16.MR:4.5 - Return the relation and its next useful use

Return the relation with the meanings of its inputs and sought value, the conditions that make it applicable, and the first result it supports. Preserve this information in the calculation, model or explanation being used; a new record is needed only when the receiving work requires one.

If the relation leaves a consequential ambiguity, name the indistinguishable values or the missing contribution. The next measurement should be selected for how it can resolve that distinction. C.11.DUA helps compare the value and cost of obtaining it.

When a discrepancy calls for repair, keep open the distinct possibilities of changing the subject model, the measurement model, the subject arrangement or the measuring arrangement. Additional mathematical detail is one option. Removing an unwanted interaction or restoring the specified procedure can be simpler.

Reopen the affected part when the target conditions, measuring procedure, calibration range or consequential influence changes. Use B.5.MPC.R when that change also affects connected physical, mathematical and computational work.
