1. Why EA Still Fails Traditional EA fixates on documentation, not delivery. Outcomes–speed, resilience, compliance–remain elusive. 2. VSI's Four-Layer Model Layer 1 –
- Strategy &
Capabilities: Cap
Map tool aligns business OKRs to tech capabilities. Layer 2 –
- Domain-Driven Design: Micro-front-doors expose cohesive APIs; Bounded Contexts prevent data coupling. Layer 3 –
- Shared Services Mesh: Identity, logging, observability, and event bus standardized across teams. Layer 4 –
- Governance-as-Code: Open-Policy-Agent (OPA) gating every build pipeline. 3. Security by Default * Zero-trust policy baked into reference architectures. * SBOM scanning integrated into CI/CD for supply-chain integrity. 4. Toolchain & Accelerators * EA Canvas (Saa
S dashboard) gives real-time heat-maps of tech debt. * Pattern Library of 120+ Terraform/Cloud
Formation modules. 5. Metrics that Matter
- Lead-time for change | 40 %
- Defect escape rate | 55 %
- Compliance audit prep time | 70 % 6. Case Study Snapshot A civilian agency re-platformed 27 legacy apps–saving $18 M TCO–while hitting FISMA High controls. 7. Operating-Model Shift Product-centric funding replaces annual cap-ex; EA guilds mentor squads weekly. 8. Road-map Toolkit 30-60-90-day playbook with OKR templates and backlog seeds. 9.
Conclusion EA succeeds when it is living, measurable, and inseparable from delivery. VSI turns architecture into an adaptive advantage.
