Enterprise-Architecture Baseline and Transformation Roadmap

Context

A growing subsidiary was multiplying systems, integrations, and data centres faster than it could document them, with unclear interdependencies and no systematic architecture view. Without a shared baseline and target direction, initiatives compete, dependencies stay hidden, and change becomes expensive and risky to coordinate.

Approach

Structured the enterprise into a baseline view and a target direction with explicit dependencies and phased steps, balancing completeness against usefulness so the roadmap stayed trustworthy and actionable. Made trade-offs — sequencing, ownership, cross-domain implications — visible so leadership could make informed commitments.

Outcome

Gave Large national company’s leadership a shared enterprise-architecture baseline and a sequenced transformation roadmap, turning a broad growth ambition into managed, decision-ready change rather than accidental expansion.

• Documented baseline architecture across 39+ components (network topology, integrations, infrastructure) in standardised notation.
• TOGAF-based transformation roadmap with phases, dependencies, and risks gave management a foundation for growth decisions.
• Aligned stakeholders across executive, technical, and operations levels on a common target-state vision.

Key result

Established an EA baseline (39+ documented components) and a TOGAF-based roadmap that converted a broad growth ambition into a sequenced, dependency-aware set of decisions leadership could commit to.
