Obtain the operating construction and translate its drivers

MA.5 develops the demand–work–resource–money forecast, including capacity blocks, payment timing and action-changing uncertainty. MA.4 reconciles operating, reporting and cash accounts. MA.6 distinguishes forecasts, targets, requests and authorized allocations. Use their adequate contributions; use MA.1–3 or MA.7–8 only for unresolved resource, attribution or cohort work. FDM supplies disputed positions and conditional instruments. Actual operating feasibility remains an input from the responsible practice.

Translate that operating account into the financial view. Quantity, mix, acceptance and price produce sales; collection terms and customer behavior produce receipts. Resource use, supply commitments and purchasing terms produce expenses, purchases and payments, which need not coincide. Investment and disposal change capacity, cash and carrying amounts through different events. Recover those events before using a historical percentage.

A ratio can be a useful forecast approximation when its driver and range remain applicable. Explain why a receivable balance scales with sales, for example, and whether the assumption concerns credit sales, collection delay or losses. A stable average collection period can fail after a change in customer mix or contractual terms. A fixed lease does not fall proportionally with volume; a capacity block can produce a step increase. A total-cost percentage that fitted the old range may conceal both.

For a monthly or seasonal account, connect each sale or purchase cohort to the period in which it is expected to settle. A broad ratio may suffice for a distant valuation year but conceal a payment gap next month. Use enough detail for the decision, and aggregate afterward where aggregation preserves that answer. The mere availability of many spreadsheet periods does not make the underlying timing estimate more reliable.
