ECO.1:4.1 - Recover the decision and the consequential numbers
Name the actor’s choice, the useful result sought and the period in which resources must be available. Separate alternatives that produce different results or leave different obligations. Reuse the resource and cash-flow account already prepared by MA or FIN.
Follow only numbers whose interpretation can change that choice. For each, ask what it denotes: an offered exchange, a past transaction, a budget allocation, an anticipated future exchange, a forgone alternative or a weight in a model. Recover the quantity, quality, location, time and access conditions that matter. “Steel at 500” is not yet a price for a specified supply.
