Bar span = P25–P75 lead time uncertainty. Solid fill = procurement window. Solid right edge = RIS date; orange marker = construction start. Order-by dates use the earlier of the two milestones, since equipment must be on site before construction begins. Recommend issuing PO no later than the P50 (center) date. Calculation: Order By = governing milestone − (12-mo forecast lead time + internal review + shipping).

Slip = days already past the recommended order-by date + order delay scenario, assuming the item is on the critical path to its milestone. Project slip = worst item. Cost exposure = slip (months) × (monthly LD + monthly AFUDC). Planning estimate, not a contractual calculation.
