EA Charter-Digitsl Transformation Program-ABC Bank

Enterprise Architecture Charter (Digital Transformation Program)

1. EA Program Overview

Program Name: ABC Bank Digital Transformation – Multi-Cloud & Hybrid Modernization

Duration: 4 Years (FY 2025–2029)

Scope:

• 200+ applications across Retail, Corporate, Treasury domains

• Multi-cloud deployment: Azure & GCP

• On-Prem: CBS, LMS, LOS

• Hybrid connectivity between Cloud & On-Prem

• Business, technology, data, security, compliance, and governance alignment

Purpose:To enable a secure, scalable, and compliant modernization of ABC Bank’s enterprise systems, improving operational efficiency, accelerating product launches, and ensuring regulatory compliance.

2. Vision & Mission

Vision:To build a resilient, agile, and cloud-native enterprise architecture that supports ABC Bank’s business goals and regulatory requirements.

Mission:

• Define target architecture and standards for hybrid multi-cloud adoption.

• Govern solution designs to ensure compliance, security, and scalability.

• Enable rapid modernization of 200+ applications through phased waves.

• Institutionalize EA governance, principles, and metrics.

3. EA Principles

1. Cloud-Smart: Leverage Azure/GCP efficiently; use on-prem for core systems where required.

2. API-First: All integrations and services exposed via APIs.

3. Security by Design: Zero Trust, PII protection, access certification.

4. Data Residency & Compliance: PII remains in India; follow RBI & SEBI regulations.

5. Automation & Observability: DevSecOps, CI/CD, telemetry dashboards, automated monitoring.

6. Reuse & Standardization: Reusable microservices, container images, and architecture patterns.

7. Vendor Neutrality & Cost Optimization: Avoid lock-in; monitor TCO.

4. Governance & Engagement

Reporting Structure:

• EA Team reports to CTO Steering Committee

• Architecture Review Board (ARB) approves standards and exceptions

• Monthly EA Clinics for tactical alignment

Stakeholders:

• CTO / CIO: Strategic guidance

• CISO: Security & compliance

• Business Heads: Validate capability alignment

• Domain Architects / SMEs: Technical expertise

• PMO: Program management & milestone tracking

RACI Example:

Activity	Responsible	Accountable	Consulted	Informed
EA Principles Definition	EA Lead	CTO	Domain Architects, CISO	PMO, Business Heads
Target Architecture Approval	EA Lead	CTO	Cloud CoE, Security	PMO, Business
Migration Wave Planning	EA Team	CTO	Business, SMEs	PMO, Stakeholders
Governance Reviews	ARB	CTO	Security, EA Team	Project Teams

5. Scope & Boundaries

In Scope:

• EA for 200+ applications

• Cloud migration strategy & reference architecture

• Security, compliance, and regulatory alignment

• Governance, principles, and standards enforcement

• KPI tracking & reporting

Out of Scope:

• Day-to-day operations of individual applications

• End-user support for non-modernized apps

• Vendor-specific infrastructure management outside defined standards

6. Key Artifacts

• EA Charter & Mandate

• Business Capability Map & Application-to-Capability Mapping

• 6R Assessment & Migration Wave Plan

• Target Architecture & Reference Architecture Documents

• EA Governance Model & ARB Decision Logs

• KPI Dashboard & Metrics Tracking

• Lessons Learned & Continuous Improvement Reports

7. Phased Engagement Approach

Phase	Duration	Key Activities	Output / KPI
Phase 1 – EA Foundation	Weeks 1–8	Charter creation, capability mapping, principles, RACI	EA Charter approved, Governance cadence defined
Phase 2 – Assessment & Target Architecture	Weeks 9–24	Portfolio assessment, 6R strategy, workload placement, gap analysis, TSA	Target Architecture approved, Wave Plan baselined, KPI alignment
Phase 3 – Execution Oversight	Weeks 25–104	Migration oversight, DevSecOps integration, ARB reviews, incident handling	Deployment frequency ↑, MTTR ↓, EA compliance ↑95%
Phase 4 – Continuous Optimization	Year 2–4	Cost & performance optimization, continuous EA governance, lessons learned	Loan approval ↓60%, cloud cost ↓25%, NPS +25

8. KPI & Metrics

• Business: Loan approval turnaround, product launch velocity, NPS

• Technology: Deployment frequency, MTTR, cloud cost efficiency, uptime

• Governance: EA compliance, architecture deviation, incident resolution

• Security & Compliance: PII breaches = 0, audit pass rate ≥95%

9. Risk & Mitigation

• Top Risks: Application migration failures, PII exposure, cloud cost overrun, regulatory non-compliance, SLA breaches, DevSecOps adoption challenges.

• Mitigation: Phased waves, automated testing, access certification, cost monitoring, ARB approvals, KPI dashboards.

• (Full top 50 risk register maintained separately.)

10. Approval & Review

Approved By: CTO, CISO, CIO, EA Lead

Review Cadence: Annual review & updates based on technology trends, regulatory changes, and business priorities.

✅ Talking Points for Interview:

• Emphasize your role in creating, enforcing, and evolving this EA Charter.

• Highlight principles, governance model, KPIs, artifacts.
