We partnered with a major NSW transport agency to rebuild and modernise its Enterprise Architecture (EA) practice after several failed attempts. The agency faced widespread dissatisfaction with its EA function, which was seen as outdated, slow, and disconnected from business priorities.
The CIO engaged us to resurrect EA as a credible, forward-looking discipline, capable of shaping IT strategy and guiding investments in line with the agency’s transformation agenda.
By introducing contemporary architecture methods, establishing a strong governance authority, and aligning IT strategy with the agency’s future vision, we uplifted EA maturity, restored executive confidence, and enabled smarter, ROI-driven technology investments.
The Enterprise Architecture practice, Design Authority established and fully operationalised. A future-ready IT strategy and roadmap were developed in alignment with the agency vision, while cloud platform optimisation delivered greater agility and measurable ROI.
The Challenge
The organisation operates under a highly autonomous, federated model with six diverse business units—ranging from engineer-to-order and process manufacturing to services and maintenance.
Strategic Challenges
- Lack of Trust in EA: Executives viewed EA as outdated and unable to meet business needs.
- Failed EA Attempts: Multiple prior efforts to establish an effective EA practice had not delivered results.
- Soaring IT Costs: Escalating operational expenses and wasteful technology spending with little to no measurable ROI.
- Weak Business Alignment: Technology investments lacked clear linkage to strategic outcomes.
- Slow Responsiveness: EA was perceived as a bottleneck rather than an enabler of transformation.
IT Challenges
- Fragmented Governance: No effective architecture authority to guide standards and decisions.
- Technology Debt: Legacy systems and siloed solutions constrained agility and innovation.
- Cloud Optimisation Needs: Inefficient use of cloud platforms limited scalability and cost effectiveness.
- Inconsistent Standards: Lack of clear principles, guidelines, and reference architectures across projects.
Our Approach
- Strategy & Alignment
- Developed an IT strategy and roadmap tightly aligned to the agency’s future business strategy.
- Pivoted EA from a compliance-driven function to a strategic enabler of transformation.
- Operating Model & Governance
- Designed and operationalised the Design Authority, chairing the forum and setting its terms of reference.
- Represented IT in cluster-wide governance forums to ensure consistency and alignment.
- Technology Enablement
- Created target state and transition architectures, providing clarity for future investments.
- Optimised cloud platforms to improve scalability, cost efficiency, and service delivery.
- Ensured all technology proposals delivered ROI and complied with agreed standards.
- Advisory & Assurance
- Acted as internal management consultants, providing architectural guidance and assurance across inflight and proposed projects.
- Delivered ongoing support to uplift EA practices while addressing legacy technology debt.
Outcomes
The key business and technology items:
