Planned spend vs actual cashflow over the project life. Planned is the contract SOV linearly smoothed across project months; revised folds in approved variations. Actuals come from AP invoices (spent) and issued POs (committed).
Planned baseline aggregates from subcontract values; planned revised folds in approved variations. Actual spent sums supplier bills by invoice date; actual committed sums purchase orders by issue date. Smoothing is linear across the project months; a future revision will use an S-curve once a baseline schedule is hooked up.
