Spreadsheet Failure ModeManual Workflow
Root Operational Bottleneck
Shared IT, facilities, and corporate service costs are allocated to business units in a spreadsheet whose driver percentages are updated by hand and whose step-down formulas loop back on themselves with circular reference warnings.
Control Hazard & Audit Exposure
Allocation bases nobody can reproduce invite quarterly disputes from general managers, and the circular model means the same input can yield different unit burdens depending on calculation order.
Deterministic Software ReplacementClient-Owned Architecture
Deterministic Cost Allocation Pipeline & Rule-Based Driver Ledger
Deterministic cost allocation pipeline that pulls driver data (headcount, seats, square footage, tickets) from source systems and applies an ordered rule set to post allocations with driver lineage.
Continuous Assertion Rule
Allocation assertion: the sum of allocated amounts must equal the shared cost pool to the cent, and every allocated line must cite the driver record and rule version that produced its percentage.
