Template
Allocate the shared costs described in {shared_costs} across the business units or products in {allocation_targets}. Follow this discipline: (1) Separate costs into directly traceable (assign immediately, no allocation needed) and genuinely shared. (2) For each shared pool, identify the cost driver that best reflects causation — headcount for HR, square footage for facilities, transaction volume for IT — and justify each choice over plausible alternatives. (3) Compute allocation rates: pool total divided by total driver units. (4) Apply rates and present the allocated result per target. (5) Sanity check: does any unit's allocated burden exceed what it would pay for the service externally? If so, flag it — allocations above market price distort decisions. (6) State which allocations are most arbitrary and how sensitive unit profitability rankings are to changing them. Never let allocation methodology masquerade as economic fact.
