ECO.2:4.2 - Construct feasible responses

Use knowledge of the actual work to consider the responses that could matter: use less per result, substitute another input, change timing or output, increase supply, or keep the present use.

Carry each response through its material complements. A replacement input can require another tool, skill, inspection or delivery arrangement. Price alone cannot establish that the substitute performs the needed function. If the substitute’s function is unresolved, use SYSE.9 to obtain and apply the needed specialist result—for the packaging case below, whether the insert protects the product under its handling conditions. OPS.14 compares the operating alternatives and their transition costs; MA.1 constructs a missing resource-use account; FIN.6 supplies an investment comparison when the response entails a longer commitment. Use only the contribution the present decision lacks.

Compare the attainable net effects over the relevant period, including transition and forgone uses. Retain differences in performance and affected interests alongside the monetary comparison.
