Enterprise Data & Decision Architecture — Regulated Environments
Professional Background
Mark Tovey is an Enterprise Architect with over 30 years of experience operating across infrastructure, enterprise systems, and regulated financial services environments.
His work spans mission-critical operational systems, large-scale ERP platforms, and APRA-regulated banking architecture. Across each stage, his focus has remained consistent: ensuring that complex systems remain coherent, accountable, and structurally sound as scale and automation increase.
This experience underpins his current focus on decision governance and coherence in AI-enabled environments.
ANZ Bank
Senior Data & Solution Architect (2018–2025)
Shaped enterprise data architecture within a large APRA-regulated bank across complex transformation programs.
Led the definition and assurance of secure, scalable, and regulatory-aligned data architectures supporting hybrid cloud modernisation and enterprise platform evolution.
Architectural focus included:
- Enterprise conceptual and canonical data modelling
- Regulatory-aligned governance (CPS 230 / CPS 234)
- End-to-end lineage and traceability frameworks
- Hybrid cloud data platform architecture
- Secure integration and event-driven design patterns
- Architecture assurance across risk, compliance, and security functions
Worked across enterprise architecture, risk, and delivery teams to stabilise decision-making boundaries prior to system implementation and optimisation.
Independent ERP & Enterprise Systems Architect
2003–2018
For over 15 years, Mark delivered enterprise systems architecture across complex ERP and business-critical platforms.
This period provided deep exposure to:
- Enterprise-scale system design and integration
- Financial and operational data structures
- Cross-functional transformation programs
- Governance and control alignment
- Business process architecture and optimisation
Working across multiple industries, he developed a structural understanding of how enterprise systems behave under scale, constraint, and organisational change.
Electricity Industry — Systems & Process Architecture
1993–2003
Mark spent a decade in the electricity sector operating across operational, systems, and process improvement roles.
This foundational experience included:
- Large-scale operational infrastructure systems
- End-to-end business process design
- Reliability-driven environments
- Cross-domain enterprise coordination
- Regulatory and compliance-driven operations
Operating in mission-critical infrastructure environments established an early discipline around system reliability, boundary definition, and accountability under constraint.
Architectural Focus
Across all engagements, Mark’s work consistently centres on:
- Clarifying decision surfaces before automation scales
- Stabilising meaning across systems and domains
- Defining architectural boundaries prior to build
- Preserving lineage, traceability, and explainability
- Aligning transformation initiatives with governance and risk frameworks
He operates upstream of delivery, defining structural invariants that allow systems to scale without silent drift.
