C.40.CD:4.3 - Construct the way for the changed problem

Try a sufficient existing operation first. Where the receiving problem breaks the old construction, locate the failed contribution: input meaning, intermediate result, operation, output condition or applicability premise.

Retain the usable contributions. Transform the input, replace a constituent or compose available operations so that each result supplies what the next step needs. C.39.RO develops that reusable operation and its support. A new physical or professional operation still needs the Method that constructs or performs it.

Trace the changed way on the target material. Distinguish a derived conditional result, an observation from a performed trial and a proposed operation whose effect remains to be obtained. The target question determines which of these can support the next use.
