PHY.5:4.6 - Use the account and reopen the affected physical choice

Return the answer with the conditions needed to use it. These may be expressed in a short derivation, an annotated model or an ordinary explanation.

Choose what the work now permits: use the simpler computation, interpret a measurement, change a drive, retain a fluctuation model, or restore an interaction. If several accounts provide complementary consequences, retain their respective uses. When a choice among available descriptions matters, C.11 supplies the comparison, including whether more inquiry is worth its cost. Use G.5 when the retained set itself must be stated: distinguish alternatives for later choice from descriptions used together for a named result. E.23 supports improvement when the chosen characteristics can judge a change.

For a new question or failed prediction, return to the influence whose omission is implicated. Change the physical variables, coupling, preparation or range, then redo the affected reduction and interpretation. B.5.MPC.R helps separate a physical-account failure from a mathematical or computational one.

The result can also change the method of work. A team may calculate a slow response with one model and delegate a short transient to another. ME.7 describes those contributions and their joins; ME.12 examines the claims needed for the combination. Each result retains the physical conditions that make it usable by the next participant.
