Frameworks: TBM, FinOps, ITIL 4

TBM provides a standard taxonomy (cost pools, IT towers, applications, services) and traceability to business value. It underpins cost models that map GL and operational usage to services. (TBM Taxonomy v5.0.1). FinOps focuses on cloud financial operations (allocation, commitment management, forecasting, anomaly detection) and a common Inform → Optimize → Operate lifecycle. ITIL 4 "Service financial management" practice links cost, risk and value for digital services, complementing TBM/FinOps with service management governance.

ServiceNow's CSDM is a reference model for CMDB/service modeling; TBM ↔ CSDM alignment is a documented pattern for cost flow and service hierarchy consistency. Use the CSDM 5 guidance + TBM/CSDM integration whitepaper to map configuration items/services to TBM solutions and cost layers.
