Linked.Archi EA on a Page Viewpoints
Viewpoints for the EA on a Page framework. Each viewpoint specifies the artifact types it includes, the stakeholders it targets, and the purpose it serves. Derived from the CSVLOD artifact taxonomy and the three core EA processes described by Kotusev. EA on a Page does not formally define viewpoints, but its artifact types and processes imply a natural set of viewpoints that practitioners use in practice. These viewpoints formalize those implicit conventions.

EA on a Page Viewpoint Catalog
Classification of EA on a Page viewpoints by the EA process they primarily support: Strategic Planning, Technology Optimization, or Initiative Delivery.
Strategic Viewpoints
Viewpoints supporting the Strategic Planning process.
Optimization Viewpoints
Viewpoints supporting the Technology Optimization process.
Delivery Viewpoints
Viewpoints supporting the Initiative Delivery process.
Governance Viewpoints
Viewpoints supporting EA governance and function.
Deciding
Evaluating options, prioritizing investments, selecting approaches.
Designing
Creating or refining architecture artifacts — solutions, standards, landscapes.
Informing
Communicating architecture to stakeholders — overviews, landscapes, roadmaps.
Governing
Compliance checking, standards enforcement, maturity assessment, governance oversight.
Business Capability Viewpoint
Shows the organization's business capabilities and how they relate to IT investments, target state architectures, and strategic roadmaps. Used in Strategic Planning to translate business strategy into IT investment direction. Primary artifacts: Business Capability Models, Target State Architectures, Value Chains.
Roadmap Viewpoint
Shows the sequenced transition from current state to target state over time. Combines Visions (target state) with Landscapes (current state) to produce time-sequenced investment plans. Used in Strategic Planning to communicate the transformation journey to business and IT leaders. Primary artifacts: Roadmaps, Target State Architectures, Landscape Diagrams.
Landscape Viewpoint
Shows the current state of the IT landscape — systems, integrations, portfolios, and inventories. Used in Technology Optimization to provide a shared factual baseline for rationalization decisions. Primary artifacts: Landscape Diagrams, Inventories, Enterprise System Portfolios, Integration Maps.
Standards Compliance Viewpoint
Shows approved technologies, patterns, and guidelines alongside the current landscape to identify compliance gaps and rationalization opportunities. Used in Technology Optimization to govern the technology stack. Primary artifacts: Technology Reference Models, Patterns, IT Principles, Technology Guidelines, Landscape Diagrams.
Solution Design Viewpoint
Shows the detailed architecture of a specific solution — components, interfaces, data models, deployment topology. Used in the Realization phase of Initiative Delivery to guide implementation teams. Primary artifacts: Solution Designs, Detailed Specifications, Interface Contracts, Deployment Architectures.
Options Assessment Viewpoint
Shows alternative solution approaches with their trade-offs, costs, risks, and alignment to standards and principles. Used in the Initiation phase of Initiative Delivery to support investment decisions. Primary artifacts: Solution Overviews, Options Assessments, Initiative Architectures, Architecture Briefs.
Governance Overview Viewpoint
Shows the EA governance arrangement — architecture tiers, governance bodies, their responsibilities, escalation paths, and the artifact types they govern. Used to communicate and assess the EA function structure. Primary concepts: Governance Bodies, Architecture Tiers, Governance Activities, EA Participants.
Maturity Assessment Viewpoint
Shows the current maturity stage of the EA practice and what processes, artifacts, governance arrangements, and benefits characterize each stage. Used to assess current state and plan EA practice improvement. Primary concepts: Maturity Stages, EA Processes, EA Artifact types, Governance Arrangements.
