“General Managers disputing IT and shared service burden allocations every quarter”
Manual Data Flow Trap
1
Stale Drivers
Driver Guess
Headcount and usage percentages typed from memory or last quarter's tab.
2
Order-Dependent
Step-Down Loops
Shared pools allocate to each other in circular formulas with iteration warnings.
3
Quarterly Fight
GM Dispute
Business units challenge burdens the model cannot explain or reproduce.
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.
Manifests in: Cost accounting allocation spreadsheet with circular reference warnings
Deterministic Replacement (After)Golden Door Standard
Headcount, seat counts, square footage, and tickets pulled from HRIS, IdP, and service systems.
2
Deterministic Order
Ordered Allocation Rules
Pools allocate in a fixed sequence with published bases; no circular references.
3
Auditable Burden
Posted With Lineage
Each allocated line posts with its driver record, percentage, and rule version.
Deterministic Software Pattern
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.
Headcount and usage percentages typed from memory or last quarter's tab.
