TOGAF 10's Three EA Capability Organizational Models Explained
This article defines the EA capability organizational model, outlines its five key elements, presents evaluation questions for existing EA capabilities, and details TOGAF 10's three recommended models: function-centered, IT-centered, and strategy-centered.
EA Capability Organizational Model Definition
The EA capability organizational model refers to the organizational structure, roles, processes, and governance mechanisms that support the development of Enterprise Architecture (EA) capabilities. It ensures EA practices align with the organization's strategic goals and effectively support business operations.
Five Key Elements
Governance Structure: Establishes decision-making authority, responsibilities, and control mechanisms.
Role Definition: Clarifies responsibilities and scope of each role within the EA team.
Processes and Methods: Defines standard processes and methodologies for EA practice.
Communication Mechanisms: Sets up effective internal and external communication channels.
Performance Evaluation: Defines standards and metrics to assess EA practice effectiveness.
Evaluating Existing EA Capability
Most enterprises have some EA function. EA capability evolves purposefully or is restarted. When any of the following situations arise, the existing EA capability must be evaluated against intended purposes and goals:
Does the existing EA capability deliver recommendations before the required type of decision (budget, charter/business case)?
Does the existing EA capability provide support for governing follow-on activity against the decision?
Does the existing EA capability support all desired decisions and governance support?
The answers directly impact process alignment, governance framework, and architecture content. The gap between current and desired EA capability feeds the roadmap to evolve the EA capability into what the enterprise needs.
