The Intent
What is Enterprise Architecture?
Enterprise Architecture is a comprehensive framework used to manage and align an organization’s technology assets, people, operations, and projects with its overall business goals. It encompasses the strategies, principles, and models that guide an organization’s selection, creation, and implementation of technology solutions.
What’s Important?
Strageticly Aligned EA ensures that investments are aligned with business goals, facilitating better decision-making and strategic planning. Improved agility through a clear roadmap and structured approach, EA enables organizations to respond quickly to changes in the business environment.
Cost-Efficient EA helps identify redundant processes and systems, optimize resource utilization, and reduce costs.
Risk Managed EA provides a framework for managing unforeseen risks, complying with regulations, bolstering security, and safeguarding data integrity.
Innovative EA fosters a culture of innovation by integrating emerging technologies and practices into the organizational fabric.

The Work
What’s involved?
Business Architecture focuses on the business strategy, governance, organization, and key business processes.
Information Architecture deals with the structure of an organization’s logical and physical data assets and data management resources.
Application Architecture describes the applications needed to manage data and support business functions.
Infrastructure Architecture encompasses the software and hardware infrastructure that supports applications and business processes.
What are the established Frameworks?
TOGAF (The Open Group Architecture Framework): A comprehensive approach for designing, planning, implementing, and governing an enterprise information architecture.
Zachman Framework: Focuses on defining and standardizing the components and processes of enterprise architecture.
FEAF (Federal Enterprise Architecture Framework): Developed by the US government to align business and IT strategies across federal agencies.
The Department
What makes up EA?
The Chief Architect leads the EA practice and ensures alignment with business goals.
Solution Architects design specific solutions that fit within the broader enterprise architecture.
Domain Architects specialize in particular areas such as data, application, or technology architecture.
Analysts support the architects by conducting research, analysis, and documentation.
How does EA integrate organizationally?
EA collaborates with other departments, including operations, development teams, and business units, to ensure cohesive and aligned strategies.
The Role
What are the responsibilities?
Enterprise Architects (EAs) are responsible for creating the enterprise architecture and ensuring it aligns with the business’s strategic goals.
Developing an EA Strategy involves crafting the vision and roadmap for the organization’s technology landscape.
Stakeholder Engagement collaborating with business leaders, technology managers, and other stakeholders to understand their needs and challenges.
Modeling and Documentation involves creating models and documentation that describe the current and future state of the enterprise architecture.
Governance and Compliance ensures that policies, standards, and architectures are adhered to across the organization.
What are the required skills?
Deep Technical Expertise with an understanding of all infrastructure, software development, and emerging technologies.
Business Acumen Knowledge of business processes, strategic planning, and financial management.
Strong Analytical Skills with an ability to analyze complex systems and processes to identify areas for improvement.
Communication and Leadership skills with a focus on articulating the value of EA while leading cross-functional teams.
Business Readiness
What must happen before EA?
For EA to be successful, it must be closely aligned with business needs.
Stakeholder Analysis identifies vital stakeholders to understand their expectations and requirements.
Business Process Mapping aims to document all existing processes to identify gaps and areas for improvement.
Strategic Planning initiatives focus on the organization’s strategic objectives and priorities.
How do you build a case for EA?
Cost Benefit Analysis demonstrates an EA framework’s potential savings and benefits.
Risk Assessments identify gaps associated with current practices and how EA can mitigate them.
Value Proposition clearly articulates how EA brings value to the organization in terms of efficiency, agility, and innovation.
Organizational Readiness
What are the essential cultural aspects?
For EA to thrive, the organization must foster a culture that supports collaboration, innovation, and continuous improvement.
Leadership Support with commitment from top management to drive EA initiatives.
Change Management creates processes to manage the cultural shift towards an EA-driven approach.
Are there technical considerations?
Technical readiness ensures that the organization’s infrastructure supports the EA framework.
Current State Assessment helps evaluate the existing environment to identify gaps and areas for improvement.
Capability Development highlights investments in tools, technologies, and training to support EA activities.
Is process improvement necessary?
Effective EA requires well-defined processes for governance, decision-making, and implementation.
Governance Frameworks establish clear policies and standards for EA practice.
Lifecycle Management processes are used to manage the entire lifecycle of IT assets, from planning to retirement.
