Costing Business Services for TBM

Global Mining Organisation – Foundation for IT Cost Transparency & TBM Adoption

TBM Financial View
Conversations That Kill Trust (and How TBM Fixes Them)
TBM Financial Planning

Executive Summary

Led the foundational phase of Technology Business Management (TBM) adoption by defining and costing technical services across the infrastructure landscape. This initiative created a robust financial model linking technology cost pools to technology resource towers (e.g., data center, servers, storage, networks), delivering clear unit costs and consumption transparency for these services.  This project established the essential groundwork for subsequent TBM phases, preparing the technical resource towers ready for next layer alignment to Business Services. We delivered accurate technical tower costing, improved financial visibility, and stronger IT, Finance and Business collaboration.

The Challenge

  • No standardised technical services or infrastructure relationships
  • Inability to trace spend to service outcomes
  • Fragmented service consumption and accountability
  • Difficulty aligning IT costs with business expectations
  • TBM blocked by missing foundational structure

The Solution

Introduced a structured costing model and TBM readiness framework.

  • Develop a Structured Technical Service Costing Model. Defined/costed services, mapped infrastructure relationships, created master catalogue
  • Financial Alignment & TBM Readiness. Connected consumption to costs, developed unit models, visual reporting, standardised for new services
  • Collaboration Framework. Facilitated workshops with IT, Finance, and Business stakeholders to align on service definitions and cost drivers
  • Built a reusable TBM Playbook . Established a repeatable framework adopted as the organisation-wide standard for introducing and costing new services

Results at a Glance

  • First formal taxonomy model linking infrastructure to costs to technology towers
  • Provided a reusable framework for ongoing TBM
  • Enabled transparency across core technical services
  • Enabled greater IT/Finance/Business collaboration
  • Delivered a solid foundation for future state Business Service costing

My Role & Insights

My Role:

I was responsible for leading this foundational costing initiative. I authored the service definition framework, facilitated cross-functional workshops with service owners, business partners, and senior leadership, and helped developed the financial mapping model. I also managed vendor input and internal reporting, ensuring deliverables aligned with the broader TBM goals. My leadership ensured this framework was embedded in the organisation as the first phase in achieving full TBM maturity.

  • A clear agreement around service definitions are essential before attempting alignment.
  • Collaborating the IT, Finance and Business views across the teams, builds trust and accountability.
  • Starting with cost pools to technology resource towers builds for understanding & realistic transparency.
  • Developing a repeatable frameworks accelerates your TBM adoption.
  • Building across phased rollouts delivers incremental value and sustainability.
