MMP.9:4.5 - Return the result and revise the construction when needed
Return the reduced law, sufficient bound or located obstacle with the assumptions that affect its use. An existing derivation and calculation can carry this information. Explain which discarded contribution was replaced, how to initialize and run the replacement, and which question it answers.
If a bound settles the working question, use it. If the result is too weak, locate why: uncertain initial influence, unresolved higher moment, long memory, error amplification, or information unavailable to an action. Improve that contribution or retain more of the source model. A mathematical construction can also show that the proposed simplification offers no saving.
Reopen the affected construction when the source law, initial class, inputs, observation, horizon or required output changes. Keep conclusions whose conditions still hold. In a model of a working method, ME can use the comparison to design a different method or representation; the actual work must still provide the quantities and relations assumed in the model.
