• Ensure architectural decisions are documented, communicated, and aligned with agreed transformation objectives.

D. ODA Alignment and Architecture Governance

• Ensure solution designs align with TM Forum ODA principles, architecture standards, and target-state design guidelines.
• Assess the applicability of ODA components and their interactions across the OSS/BSS landscape.
• Support architecture governance, design reviews, and architecture decision-making.
• Identify deviations from approved architecture and recommend appropriate corrective actions.
• Maintain traceability between business capabilities, functional requirements, solution designs, and implementation components.

E. Transformation and Implementation Support

• Provide architectural guidance throughout solution design, development, integration, migration, and testing.
