5. Domain Architect

Role and Responsibilities: The Domain Architect specializes in specific areas or domains within the enterprise, such as data, infrastructure, applications, or security. Their job is to ensure that architecture within their domain aligns with the overall enterprise architecture, while also addressing specific domain needs.

Key Responsibilities:

• Develop architecture within their domain, such as Data Architecture, Application Architecture, Security Architecture, or Technology Architecture.
• Ensure domain-specific architecture is aligned with the enterprise-level architecture.
• Collaborate with solution architects to ensure domain consistency in the implementation of solutions.
• Provide expertise in their specific area, ensuring architecture decisions support the organization’s broader goals.

Skills and Qualifications:

• Specialized knowledge in areas such as data management, cloud infrastructure, cybersecurity, or application development.
• Ability to balance domain-specific needs with enterprise-wide architecture requirements.
• Strong collaboration skills to work with other architects and ensure consistency across the enterprise.
• Proficiency in domain-specific tools (e.g., for data modeling or infrastructure automation).

6. Enterprise Architecture Governance Lead

Role and Responsibilities: The Governance Lead ensures that architecture decisions comply with established policies, guidelines, and standards. This role is vital in enforcing discipline in how architecture is developed and managed, preventing scope creep, and ensuring architectural integrity.

Key Responsibilities:

• Define and implement governance structures to ensure architecture compliance across all projects.
• Monitor architecture projects to ensure they follow enterprise-wide standards and guidelines.
• Report to the C-suite on architecture governance, highlighting compliance and identifying areas for improvement.
• Manage an architecture review board to ensure all architecture decisions align with business goals and policies.

Skills and Qualifications:

• Strong understanding of architecture frameworks and governance models.
• Experience in managing compliance and risk within architecture initiatives.
• Ability to enforce standards while fostering innovation within the architectural framework.
• Excellent communication skills to engage with both technical and business stakeholders.

Collaboration with C-Suite and Product Management Teams

For an EA CoE to be truly effective, it must maintain strong communication and collaboration with the C-suite and Product Management Teams. This alignment ensures that architecture decisions are always in service of the broader business strategy.

Connection to the C-Suite

The EA CoE must regularly engage with the C-suite (CEO, CIO, CTO, CFO, etc.) to ensure that the architecture reflects the company’s strategic vision and long-term objectives. This can include:

• Enterprise Architect providing regular updates on the progress of architectural initiatives and how they support business goals.
• Business Architect working with the C-suite to refine business models and ensure the architecture supports scalability and market responsiveness.

Collaboration with Product Management Teams

The Product Management Team plays a crucial role in the successful implementation of EA CoE initiatives. As product leaders define and prioritize new product features and innovations, the CoE must ensure these align with enterprise-wide architecture standards.

• Business Analysts and Solution Architects collaborate with product managers to balance innovation with architectural consistency.
• Domain Architects ensure that product developments adhere to domain-specific requirements and do not create fragmentation within the architecture.

Conclusion

Building a successful Enterprise Architecture Centre of Excellence (EA CoE) requires the right mix of roles and responsibilities, each with specialized skills and expertise.

From Enterprise Architects who oversee the entire architectural vision to Domain Architects who ensure consistency within specific technical areas, the team must work collaboratively to align technology with business strategy.

With strong links to the C-suite and active engagement with Product Management Teams, an EA CoE can ensure that technology investments drive business growth, improve efficiency, and foster innovation across the organization.
