Shaping India’s BFSI Architecture Future: TOGAF®, EACoE and 12-Factor Practices

1. Executive Summary

Indian banks, insurers, NBFCs and regulators are at an inflection point. Rapid digitalisation through UPI 2.0, Account Aggregator, ONDC and embedded finance, combined with stringent new regulatory frameworks such as the RBI IT Governance Directions (2023), SEBI Cybersecurity Guidelines (2023), IRDAI Cloud Circular (2024) and the DPDP Act (2023), demand a unified, agile and secure approach to enterprise architecture. This playbook sets out a gold-standard roadmap for adopting TOGAF® within the Indian BFSI sector. It integrates:

- The Open Group’s globally proven TOGAF framework

- A centralised Enterprise Architecture Centre of Excellence (EA CoE) for governance, skills and artefacts

- Cloud-native “12-Factor App” practices to ensure new applications are scalable, portable and regulatory-ready

By aligning business capability maps, application portfolios, data flows and technology platforms with TOGAF, BFSI organisations can dramatically improve compliance readiness, cost efficiency and innovation capacity. Quantified Benefits: - 15–30 % faster time-to-market for new digital products and services - 20–40 % lower compliance and audit preparation costs through reusable artefacts - 10–25 % annual OPEX savings from application rationalisation and shared services - 80 % of new apps 12-Factor compliant by Year 2, reducing technical debt and improving portability Strategic Outcomes:

- A single, regulator-aligned view of the enterprise across business, data, application and technology layers - A reusable, auditable repository of architecture artefacts mapped to IndEA 2.0 and BIAN standards - A skilled internal architecture community supported by Open Group India and NASSCOM BFSI councils Executive Takeaway:

This is not just an IT exercise but a business transformation enabler. It positions Indian BFSI organisations to deliver secure, innovative and cost-efficient services at scale, while satisfying regulators and customers alike. A one-page infographic summarising TOGAF layers, the EA CoE at the centre, the 12-Factor overlay and the ROI numbers is recommended for board-level presentations.

Regulators should treat TOGAF as a shared vocabulary and evidence framework to raise architecture maturity, lower systemic risk and reduce compliance friction across the BFSI sector, rather than as a prescriptive, one-size-fits-all requirement.

2. Strategic Context – Why Now

Indian BFSI institutions face a perfect storm of disruptive forces:

• Regulatory intensity is rising with RBI’s IT Governance Directions, DPDP Act 2023 and SEBI’s Cybersecurity guidelines.

• Customer expectations are shaped by UPI, Paytm, PhonePe and super-app ecosystems — instant, seamless and personalised.

• Technological change with cloud, AI/ML, Open Finance and CBDC pilots is accelerating.

• Competitive pressure from fintechs, BigTech and embedded finance models demands faster innovation and lower cost-to-serve.

Without a unified architecture framework, banks and insurers risk duplication, security exposures, regulatory penalties and spiralling costs. TOGAF adoption provides a proven, vendor-neutral framework to rationalise portfolios, govern technology change and link business strategy to execution.

3. Vision

y 2028, leading Indian BFSI organisations will operate with:

• A living enterprise architecture repository aligned to IndEA 2.0, BIAN and ISO/IEC 42010.

• A central EA CoE driving governance, reuse and talent development.

• Cloud-native, 12-Factor compliant applications with low technical debt.

• Business–IT alignment dashboards showing regulatory, cost, risk and innovation metrics to CXO and board level.

• Interoperability with Open Finance, Account Aggregator and CBDC platforms.

This vision enables secure, innovative, customer-centric financial services at lower cost and risk.

4. Drivers and Challenges

Key Drivers:

• Compliance with RBI, SEBI, IRDAI, PFRDA digital governance requirements.

• Cost pressure and need for application portfolio rationalisation.

• Digital transformation initiatives (super-apps, instant lending, AI-driven underwriting).

• Talent shortages in architecture and DevOps requiring a common language and method.

Challenges:

• Fragmented architecture practices across business units.

• Legacy monolithic systems that hinder 12-Factor adoption.

• Limited executive awareness of architecture’s business value.

• Coordination with multiple regulators and global parent banks.

TOGAF, when adapted to Indian BFSI context, provides a structured way to address these.

5. Global & Indian Adoption Snapshot

• Global: 80%+ of Fortune 500 financial institutions (e.g. JPMorgan, Barclays, HSBC) report using TOGAF or variants for EA governance. Many combine it with BIAN and Agile Architecture to manage large-scale digital platforms.

• India: Public and private banks (SBI, ICICI, HDFC) have EA initiatives inspired by IndEA and TOGAF. Regulators like NPCI and GSTN use architecture frameworks for scalability. NASSCOM’s BFSI Council has launched EA skill programmes with The Open Group India.

• Trend: Moving from “paper frameworks” to living, model-based architecture repositories integrated with DevSecOps pipelines.

This shows that TOGAF is no longer theoretical — it’s a mainstream toolset adapted to local needs.

6. EACoE – The Institutional Anchor

Core Functions:

• Maintain a single EA repository of business, data, application and technology artefacts.

• Provide architecture review boards and decision rights aligned to RBI/SEBI guidelines.

• Drive capability maturity assessments and portfolio rationalisation.

• Curate patterns and blueprints for cloud, security, 12-Factor apps and regulatory compliance.

• Lead training and certification of architects and stakeholders (TOGAF, BIAN, IndEA).

Benefits:

• CXOs/Boards get clear dashboards of risk, cost and innovation metrics.

• Regulators see consistent evidence of compliance architecture.

• Business units receive faster, cheaper and more predictable IT change.

• Technology teams benefit from reusable patterns, reducing defects and audit findings.

7. ROI Scenarios

TOGAF adoption delivers tangible and measurable returns for Indian BFSI organisations:

8. Capability Maturity Assessment

A maturity model helps track progress:

9. Value Stream Mapping

Value stream mapping within TOGAF ensures that architecture effort is tied to business outcomes. For Indian BFSI, examples include:

• Digital Onboarding: Map customer journey, underlying apps, APIs and data flows; identify bottlenecks.

• Lending & Credit Decisioning: Show how risk models, KYC, account aggregator feeds and credit bureaus integrate.

• Payments & UPI Integration: Map end-to-end flows from front-end apps to NPCI and settlement systems.

• Regulatory Reporting: Link data lineage from transaction systems to reporting dashboards to ensure compliance.

These mappings allow prioritisation of architecture work based on value rather than technology alone.

10. Skills & Certification Roadmap

A structured skills programme ensures sustainability:

• Architects: TOGAF 10 certification; BIAN & IndEA exposure; cloud and security certifications (AWS, Azure, PCI DSS).

• Business Analysts: Business capability modelling, value stream mapping.

• Developers: 12-Factor app practices, DevSecOps, microservices design.

• Executives/Boards: EA value awareness workshops, regulatory implications.

Partnerships with The Open Group India, NASSCOM BFSI Council and local universities can accelerate skill pipelines.

11. Tools & Technology Enablement

Tool support is essential to make TOGAF “live”:

• EA Repositories: LeanIX, Bizzdesign, Avolution ABACUS or open-source options integrated with CI/CD.

• Modelling Standards: ArchiMate® for visualising TOGAF artefacts.

• Integration with DevSecOps: Link architecture artefacts to Jira, GitLab, Jenkins for traceability.

• Automation: Use APIs and bots to populate asset inventories and compliance dashboards.

Indian BFSI firms should select tools that support local data residency and regulatory requirements.

12. Risk Appetite & Exception Handling

Enterprise architecture must respect each organisation’s risk appetite:

• Define risk thresholds for availability, security, regulatory non-compliance.

• Embed these thresholds in architecture decision templates and review boards.

• Create an “exception process” for urgent business needs with documented risk acceptance.

• Map architecture risks to enterprise risk frameworks already reported to regulators.

This approach ensures TOGAF adoption does not become bureaucratic but remains risk-aware and business-friendly.

13. Stakeholder Value Map

Mapping benefits for each key stakeholder creates buy-in:

14. Integration with 12-Factor Apps

The 12-Factor App methodology (portability, scalability, CI/CD readiness) complements TOGAF by providing standards at the application level:

• TOGAF addresses enterprise-wide architecture (business, data, application, technology layers).

• 12-Factor addresses micro-level practices for building cloud-native apps.

Indian BFSI organisations can integrate these by:

• Including 12-Factor checklists in EA review boards.

• Maintaining reference implementations (e.g., secure API gateways, config-as-code).

• Training developers alongside architects to ensure new apps are compliant.

• Tying KPIs (e.g., % of apps 12-Factor compliant) into EA CoE dashboards.

This reduces technical debt, improves portability across hybrid cloud, and satisfies future regulatory expectations on resilience.

15. Alignment with Indian Standards and Ecosystem

TOGAF adoption should not be “imported” wholesale but tailored to Indian realities:

• IndEA 2.0: Adopt its layered reference architecture and maturity models.

• BIAN: Use for core banking service definitions.

• RBI, SEBI, IRDAI Guidelines: Embed controls (data localisation, cyber resilience, cloud use) in architecture artefacts.

• Digital Public Infrastructure: UPI, Account Aggregator, ONDC – ensure interoperability patterns are documented.

• NASSCOM / MeitY Initiatives: Use their frameworks for skills and standards alignment.

This localisation ensures your EA CoE produces artefacts regulators understand and accept.

16. Change Management & Communication Plan

TOGAF adoption succeeds when stakeholders understand why and how:

• Stakeholder Mapping: Identify champions in business, technology and risk functions.

• Communication Toolkit: Executive briefings, infographics, townhalls, intranet pages explaining benefits.

• Quick Wins: Pilot projects (e.g., regulatory reporting, new API platform) to demonstrate value.

• Feedback Loops: Regular surveys and open channels to refine EA CoE processes.

• Cultural Sensitivity: Recognise Indian BFSI’s hierarchical structures; use top-down sponsorship with bottom-up inputs.

17. Collaboration Plan

A robust collaboration plan extends TOGAF’s reach beyond internal silos:

• Internal: Architecture communities of practice across business units.

• External: Partner with The Open Group India, NASSCOM BFSI Council, local universities for talent pipeline.

• Regulatory: Engage RBI, SEBI, IRDAI proactively to co-create reference patterns and demonstrate compliance.

• Vendor Ecosystem: Include major IT vendors and fintech partners in architecture reviews to ensure alignment.

• Knowledge Sharing: Publish anonymised case studies at industry forums to build credibility.

18. Visual Summary Slide

Although a Word document can describe the framework, a single infographic makes it board-friendly. Recommended elements for the slide:

• Center: EA CoE as the hub.

• Outer Ring: TOGAF layers – Business, Data, Application, Technology.

• Overlay: 12-Factor App practices (portability, scalability, CI/CD).

• Inputs: Regulatory drivers (RBI, SEBI, IRDAI, DPDP Act).
