# CSDM V3 Framework Mapping: TBM Council 3.02

- Title: CSDM V3 Framework Mapping: TBM Council 3.02
- Video URL: https://www.youtube.com/watch?v=I1zjjmh6xt8
- Playlist position: 68
- Frameworks discussed: CSDM, TBM Council, ATUM
- Evidence basis: YouTube MCP playlist metadata, `yt-dlp` chapter metadata, and a local `faster-whisper` transcription recovered from the video audio after MCP transcript calls failed on 2026-03-26.

## Short summary
This session is the clearest finance-oriented mapping in the set. It explains TBM / ATUM as a way to move from the general ledger through cost pools, IT towers, products and services, business units, and capabilities, then maps those finance-control concepts into the CSDM structural model.

## Key mapping concepts
- General ledger to cost pools to IT towers to products/services to business units/capabilities
- Business unit and business capability as strong top-down bridge points into CSDM
- Shared services and service delivery mapped into business-service and technical-service layers
- IT towers mapped into CI and infrastructure class structures
- Product models and contracts proposed as a pragmatic way to attach cost information inside a mature CSDM rollout

## Notable terminology used
- TBM Council
- ATUM
- Cost pools
- General ledger
- IT towers
- Business unit
- Shared services
- Service delivery

## What still seems valid
Very relevant for ontology work that needs cost semantics and governed roll-up paths. The enduring value is the attempt to trace financial allocation through services, capabilities, and infrastructure rather than treating finance as an external disconnected reporting layer.

## What appears outdated or version-specific
The session is tied to TBM / ATUM 3.02 and carries explicit Aptio-era heritage. It also acknowledges gaps, especially around projects, investments, and labor, where CSDM does not provide a direct mapping. Those limitations should be preserved when adapting the model.

## Transcript
Local transcript recovered on 2026-03-26 by downloading the audio and transcribing it after the YouTube MCP transcript path failed.

Cleaned transcript excerpt:
- `0:15-1:20`: TBM Council / ATUM is presented as a vendor-agnostic but Aptio-influenced framework for understanding IT financial management, while CSDM is framed as the structural model for digital products and services across the platform.
- `2:15-3:35`: The core TBM taxonomy is described as money flowing from the general ledger into cost pools, then upward through IT towers and into products, services, business units, and capabilities so executives can finally see where IT spend goes.
- `4:05-6:20`: The mapping into CSDM starts with business unit and business capability, then shared services into business service, service delivery into technical service, IT towers into CI classes, and product models/contracts as the pragmatic place to begin attaching cost data.

Chapter landmarks recovered from the YouTube page:
- `0:46` CSDM and TBM
- `2:17` TBM taxonomy
- `3:52` Mapping

## Relevance to current ontology work
Very high relevance where the ontology has to connect digital products and services to cost attribution, showback, or governance evidence. This is a strong historical source for attaching financial roll-up paths to service and infrastructure semantics without losing the bridge to business capability.
