The blueprint highlights gaps in data foundations, integration patterns, and environment strategies, enabling proactive remediation and scalability planning.

3. TOGAF® Standard Overview

TOGAF (The Open Group Architecture Framework) provides a structured approach to enterprise architecture through the Architecture Development Method (ADM) and a comprehensive Content Framework. The ADM cycle includes phases from Preliminary through Architecture Change Management, ensuring iterative and governed architecture development.

Key components:

• ADM Phases: Preliminary, Vision, Business, Data, Application, Technology, Opportunities & Migration, Implementation Governance, Change Management.
• Content Metamodel: Defines catalogs, matrices, and diagrams for consistent artifact creation.

4. Mapping ServiceNow Blueprint to TOGAF ADM

4.1 Preliminary Phase

Establish architecture principles and governance. The blueprint incorporates ServiceNow-specific principles and decision forums.

4.2 Phase A: Architecture Vision

The blueprint provides a baseline view that supports the Statement of Architecture Work and clarifies scope and objectives.

4.3 Phases B–D: Domain Architectures

• Business Architecture: Captured via Value Blueprint.
• Data Architecture: CMDB and CSDM foundations.
• Application Architecture: ServiceNow applications and external systems.
• Technology Architecture: Hosting, instance strategy, and infrastructure.

4.4 Phase E/F: Opportunities & Migration Planning

Blueprint outputs feed into gap analysis and roadmap development.

4.5 Phase G/H: Governance & Change Management

TOGAF recommends continuous compliance checks; ServiceNow Impact accelerators suggest quarterly blueprint refreshes.

5. TOGAF Content Framework Alignment

The blueprint aligns with TOGAF artifact types:

• Catalogs: Application inventory, integration lists.
• Matrices: Application-to-data relationships, RACI charts.
• Diagrams: Integration context, instance topology.

Deliverables include:

• Architecture Definition Document (blueprint pack).
• Architecture Roadmap (actionable next steps).
• Transition Architecture (future-state diagrams).

6. Execution Approach

Phase A ,  Kickoff & Intake

• Align on goals, scope, and stakeholders.
• Collect baseline data using structured questionnaires.

Phase B ,  Working Sessions

• Document data, applications, integrations, and infrastructure.
• Define governance and architecture principles.

Phase C ,  Synthesis & Playback

• Compile blueprint pack using standardized templates.
• Validate with stakeholders and agree on remediation actions.

Phase D ,  Operationalization

• Store artifacts in a central repository.
• Schedule quarterly refresh cycles.

7. Benefits of TOGAF Alignment

• Audit Readiness
  TOGAF artifacts—such as Architecture Definition Documents, catalogs, and matrices—are globally recognized and often referenced in compliance frameworks. Aligning your ServiceNow blueprint with TOGAF ensures that customers can demonstrate structured architecture governance during audits, regulatory reviews, and security assessments.
• Traceability
  TOGAF emphasizes linking business drivers and objectives to architecture components through its Content Metamodel. By adopting this approach, the ServiceNow blueprint provides clear traceability from strategic goals (e.g., improving IT service delivery) down to technical elements like integrations and hosting models. This linkage supports impact analysis and prioritization of changes.
• Integration with EA Practice
  Many organizations already maintain enterprise architecture repositories based on TOGAF or similar frameworks. A TOGAF-aligned ServiceNow blueprint fits seamlessly into these repositories, reducing duplication and enabling cross-domain visibility. This integration ensures ServiceNow is not treated as a silo but as part of the broader enterprise architecture landscape.
• Consistency and Standardization
  Using TOGAF principles and artifact types (catalogs, matrices, diagrams) brings consistency across architecture documentation. This standardization improves communication between ServiceNow teams and enterprise architects, reducing misunderstandings and accelerating decision-making.
• Future-State Planning
  TOGAF’s ADM cycle supports iterative development and transition architectures. Aligning the blueprint with these phases enables customers to move from current-state baselines to target-state designs in a structured, governed manner.

8. Recommendations for Customers

• Engage ServiceNow Platform Architects and EA Teams Early
  Collaboration between ServiceNow specialists and enterprise architects ensures that the blueprint reflects both platform-specific details and enterprise-wide principles. Early engagement avoids rework and accelerates alignment with governance standards.
• Use TOGAF Terminology in Deliverables for Consistency
  Incorporate TOGAF terms such as “Architecture Vision,” “Baseline Architecture,” and “Transition Architecture” in your blueprint documentation. This makes it easier for EA stakeholders to interpret and integrate ServiceNow artifacts into their existing frameworks.
• Leverage ServiceNow Impact Accelerators and Templates for Faster Execution
  ServiceNow provides pre-built templates and accelerators for architecture blueprinting. Combining these with TOGAF guidelines allows customers to produce high-quality, compliant artifacts quickly. This approach reduces time-to-value and ensures governance from the outset.
• Establish a Refresh Cadence
  Architecture is not static. Schedule quarterly or semi-annual reviews of the blueprint to maintain relevance and compliance. TOGAF’s Change Management phase supports this continuous improvement model.
• Integrate with Governance Forums
  Embed blueprint reviews into Architecture Review Boards or similar governance structures. This ensures decisions about ServiceNow align with enterprise standards and strategic priorities.
