Prescriptive cost models for shared services and business applications - Legacy
L1 Costing – Shared Services provides a complete visibility of fully loaded IT infrastructure cost, infrastructure shared services showback, and lays foundation for future growth. L2 Costing – Business Applications provides cost of applications and end user, aligns applications to business units, furnishes cost information to support each business unit in business terms.

This feature is available only when you own an ITBM Analyst license.
L1 Costing – Shared Services
The specifications of the L1 Costing – Shared Services are:
- The cost bucket layer is tied to the ITFM bucket table [itfm_bucket] and the cost buckets are specific to a model.
- IT shared service segment accounts (the middle layer in this model) are sourced from the IT shared service table [itfm_shared_service].
- The business unit layer is tied to the platform business unit table [business_unit].
L2 Costing – Business Applications
The specifications of the L2 Costing – Business Applications are almost the same as L1 Costing – Shared Services. However, there is an additional layer for applications. Enterprise Architecture (formerly APM) Business Application [cmdb_ci_business_app] table is the source of accounts to the applications segment. Or, it can be Application [cmdb_ci_appl] table or other custom tables.

ITFM prescribed metrics
- Allocate to Business Unit based on Change Request volume based on CIs
The metric allocates shared service cost to business unit based on the following weighting table:
그림 3. Allocate to Business Unit based on Change Request volume based on CIs - The Change Request [change_request] table provides a list of all change requests and their related configuration item.
- The CMDB [CMDB_ci] provides a list of all configuration items and their related department.
- The Department [cmn_department] table provides a list of all departments and their business unit.
