Architecture Compliance Review Checklists Knowledge-Based Study

Study notes

1. Purpose of Architecture Compliance Checklists

   In the TOGAF Standard, an Architecture Compliance Review is a formal evaluation conducted at key milestones to ensure that an implementation project conforms to defined enterprise architecture specifications, standards, and governing principles.

   Checklists serve as structured inspection aids for reviewers and project teams. They provide a repeatable, rigorous baseline of questions covering technical domains, architectural design choices, and operational requirements. Key objectives of using compliance checklists include:

   • Consistency: Establishing uniform criteria across disparate projects and diverse project teams.
   • Gap Identification: Promptly revealing variance, non-compliance, or required dispensations before deployment.
   • Risk Mitigation: Preventing unapproved architectural divergence, security vulnerabilities, and vendor lock-in.
   • Governance Evidence: Documenting due diligence and adherence to architecture governance frameworks.

   Platform and Infrastructure Layers

   Infrastructure compliance reviews ensure baseline compute environments align with operational support standards and strategic technology platforms.

   Hardware and Operating System Checklist

   Focuses on physical and virtual compute resources, ensuring standard deployment practices and lifecycle viability:

   • Compatibility with standard enterprise hardware platforms and virtualization profiles.
   • Operating system distribution, release level, patch management, and vendor support lifecycle.
   • Clustering, load balancing, multi-zone availability, and physical redundancy capabilities.
   • Hardware-level monitoring hooks and power/cooling/data center constraints.

   Software Services and Middleware Checklist

   Evaluates common enabling software that bridges applications and base operating platforms:

   • Conformance to enterprise messaging protocols, service buses, and API gateways.
   • Standardized runtime environments, web servers, and container orchestration platforms.
   • Interoperability mechanisms, transaction managers, and cross-platform communication patterns.

   Functional Software and Enterprise Data Assets

   These checklists assess business software designs and data management practices against architecture governance principles.

   Applications Checklists

   Examines application structure, modularity, and integration characteristics:

   • Modularity and Cohesion: Clear boundaries, separation of concerns, and minimal tight coupling between components.
   • Interface Design: Adherence to enterprise API guidelines, RESTful conventions, or standard data exchange formats.
   • Reusability: Leveraging shared enterprise services rather than implementing duplicate functionality.
   • User Experience and Accessibility: Alignment with corporate UI/UX guidelines and accessibility mandates.

   Information Management Checklists

   Governs enterprise data architecture, storage, and information lifecycle management:

   • Logical and physical data modeling compliance with enterprise canonical models.
   • Data ownership, stewardship, data dictionary definitions, and authoritative system of record designations.
   • Data retention, archiving, disposal schedules, and backup/restore requirements.
   • Database engine standards, data replication, and transaction isolation integrity.

   Security Assurance and Operational Governance

   Projects must undergo thorough cross-domain reviews to guarantee defensibility and long-term operational maintainability.

   Security Checklist

   Evaluates whether the solution satisfies corporate risk appetite and security architecture baselines:

   • Identity and Access Management: Integration with centralized directory services, role-based access control (RBAC), and multi-factor authentication (MFA).
   • Data Protection: Cryptographic standards for data at rest and data in transit (e.g., TLS configurations, key management).
   • Vulnerability and Threat Management: Compliance with secure coding standards, automated code scanning, and penetration testing protocols.
   • Audit Logging: Non-repudiation, tamper-evident security logging, and SIEM integration.

   System Management Checklist

   Assesses day-to-day operational manageability and supportability in production:

   • Instrumentation for health checks, performance metrics, and telemetry aggregation.
   • Integration with centralized enterprise monitoring, alerting, and incident management tooling.
   • Automated deployment routines, backup/restore procedures, and automated configuration management.

   Holistic Design Integrity and Engineering Rigor

   System-wide engineering checklists ensure that individual components combine into a coherent, high-quality, and maintainable enterprise ecosystem.

   System Engineering / Overall Architecture Checklists

   Assesses macro-level system attributes across non-functional quality dimensions:

   • Scalability and Capacity: Ability to handle anticipated transaction volume growth, horizontal vs. vertical scaling limits.
   • Resilience and Disaster Recovery: Achievement of specified Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO).
   • Architectural Coherence: Alignment with enterprise architectural principles, reference architectures, and target state visions.
   • Total Cost of Ownership (TCO): Identification of hidden operational licensing costs and long-term maintenance overhead.

   System Engineering / Methods & Tools Checklist

   Ensures software delivery processes comply with enterprise engineering standards:

   • Standardization of build pipelines, CI/CD automation, and test environments.
   • Adherence to approved architectural modeling tools, notations (e.g., ArchiMate), and repository documentation practices.
   • Quality assurance methodology, automated unit/integration testing coverage, and release management discipline.
