What Is TBM?

Technology Business Management - The Language of IT Finance

Technology Business Management (TBM) is a globally recognised framework that helps organisations understand the cost, quality, and value of the technology services they consume and deliver.

TBM bridges the gap between IT and Finance by providing a common vocabulary, standard cost taxonomy, and structured allocation model - so every stakeholder can have an informed, evidence-based conversation about IT spend.

The TBM Council Standard

TBM is governed by the TBM Council and codified in the Apptio Unified Taxonomy Model (ATUM) - the global standard for IT cost transparency adopted by thousands of enterprises worldwide.

  • Translates IT complexity into business language
  • Enables data-driven IT investment decisions
  • Aligns IT budgets to business outcomes
  • Supports FinOps & cloud cost governance
TBM Cost Model - Simplified

From Finance to Business Value

Finance Layer - General Ledger

Labor, Software, Hardware, Telecom, Facilities, and External Services.

IT Tower Layer - IT Resources

Compute, Storage, Network, End User, and IT Management.

Business Layer - Consumed By

Business units, departments, products, and projects.

The Problem

Why Most IT Cost Data Fails the Business

Without proper TBM data curation, even the best tools give you noisy, untrustworthy data. Here's what we see - and how we fix it.

Common Challenges

Unclear cost data creates uncertainty.

  • IT costs sitting in unallocated or other buckets
  • Inconsistent cost categorisation across departments
  • Finance and IT using different names for the same costs
  • Manual spreadsheet allocation models that break every quarter
  • No clear line of sight from GL entries to consumed IT services
  • Cloud costs growing with no governance or showback model
  • Executives making decisions based on bad data
The Appzster Solution

One trusted model for Finance and IT.

  • Full ATUM taxonomy mapping that eliminates unallocated buckets
  • Standardised cost categorisation aligned to TBM best practices
  • A single cost model Finance and IT both trust
  • Automated data pipelines replacing fragile spreadsheets
  • Clear GL-to-service mapping with drill-down capability
  • FinOps-ready governance with showback and chargeback models
  • Executive dashboards that turn data into decisions
Our TBM Services

Three Pillars of IT Cost Intelligence

Our TBM practice is built around three core service pillars - each designed to give your organisation a deeper level of financial control over your technology investment.

01

Data Curation & Taxonomy Mapping

We map raw General Ledger, CMDB, contract, and HR data precisely to the ATUM taxonomy. Every cost gets a home. Every IT tower gets fully populated.

  • GL account mapping to ATUM
  • IT tower & sub-tower classification
  • Vendor & contract cost alignment
  • FTE & labour cost allocation
02

Cost Allocation & Showback / Chargeback

We build the allocation rules, drivers, and models that flow IT costs all the way from infrastructure to the business units, departments, or products that consume them.

  • Multi-level allocation rule design
  • Business unit showback models
  • Department-level chargeback
  • Application portfolio cost mapping
03

FinOps & Cloud Cost Governance

We bring FinOps discipline to AWS, Azure, and GCP environments with TBM-aligned cost governance.

  • Cloud cost tagging strategy
  • AWS / Azure / GCP cost mapping
  • Apptio Cloudability integration
  • Cloud waste identification

Apptio Implementation & Optimisation

Certified Apptio expertise - from greenfield implementations to rescuing struggling existing deployments.

TBM Reporting & Dashboards

Executive-ready dashboards and operational reports from board-level summaries to drill-down operational views.

TBM Training & Enablement

Structured training programmes for IT Finance teams so they can own and operate the model confidently.

Our Approach

The Appzster TBM Data Pipeline

A structured, repeatable process that takes your organisation from data chaos to full cost transparency - in as little as 90 days.

01

Data Discovery & Source Mapping

We audit GL, CMDB, HR, contracts, cloud billing, and every relevant data source to identify what exists, what is missing, and what quality issues need resolving.

02

Data Cleansing & Normalisation

We cleanse duplicates, resolve inconsistencies, normalise naming conventions, and validate completeness before modelling begins.

03

ATUM Taxonomy Mapping

We map costs, resources, towers, applications, and services to a defensible model aligned to the ATUM taxonomy.

04

Allocation Model Design

We define and validate allocation rules and cost drivers that explain how technology is consumed throughout the business.

05

Reporting, Training & Optimisation

We deliver clear reporting, enable your team, and support continuous improvement as your estate evolves.

FAQ

TBM Questions Honestly Answered

What is TBM data curation?

TBM data curation is the process of cleansing, normalising, classifying, and mapping IT financial and operational data into a trusted model aligned to the ATUM taxonomy.

How long does a TBM implementation take?

For organisations with accessible source data, a first trusted TBM model can typically be delivered in about 90 days. The exact timeline depends on data quality and scope.

Do we need Apptio to get started?

No. We can build the taxonomy, source mappings, allocation logic, and reporting foundation whether you are implementing Apptio, improving an existing deployment, or starting with another reporting environment.

Can you help us reduce cloud spend?

Yes. Our FinOps service covers tagging strategy, cost allocation, waste identification, reserved-instance optimisation, and business-unit showback or chargeback.
