Enterprise Portfolio Architecture (EPA)

The Enduring Architectural Foundations

The Architectural Perspective

Enterprise Portfolio Architecture establishes the enduring architectural foundations through which organisations can be interpreted, understood and continually evolved. Beginning with Enterprise Definition, it progressively establishes enduring enterprise structures that remain comparatively stable as Enterprise Intent, Enterprise Context, Enterprise Evolution and Delivery Responses continually change, preserving continuity throughout Continual Enterprise Evolution.

Architectural Components

Enterprise Portfolio Architecture is established through six connected architectural components that collectively provide the structures, operational foundations, interaction, enablement, assurance and ecosystem required to sustain the discipline within continually evolving enterprises.

Enterprise Portfolio Structures

Enterprise Portfolio Structures establish the enduring architecture through which the enterprise is organised and understood.

Beginning with Enterprise Definition, Enterprise Core Capabilities provide the enduring capability foundations of the enterprise. Enterprise Core Capability-aligned Portfolios organise those capabilities into enduring planning and stewardship structures, while the Enterprise Portfolio provides the connected enterprise-wide perspective.

Enterprise Portfolio Operational Foundations

Enterprise Portfolio Operational Foundations establish the enduring objects, capabilities, artefacts and practices required to continually operate the architecture.

Enterprise Demand Objects represent the enduring need for Enterprise Evolution, while Enterprise Portfolio Capabilities, Core Artefacts and Practices provide the operational foundations through which demand and Enterprise Core Capability evolution remain continually connected.

Enterprise Portfolio Operational Interaction

Enterprise Portfolio Operational Interaction establishes how enterprise understanding and enterprise decisions continually interact with the operation of the portfolio.

Enterprise Interpretation and Decision Interaction, supported by the Operating Structure, connect the interpreted enterprise position with the decisions and responses required to continually guide Enterprise Evolution.

Enablement Structures

Enablement Structures provide the supporting capability required to establish, interpret and sustain Enterprise Portfolio Architecture within the organisation.

They comprise Application Enablement, Interpretation Enablement, Continuity Enablement, and Knowledge & Competency Enablement, providing the organisational foundations required for enduring operation.

Framework Assurance

Framework Assurance protects the integrity and consistent application of Enterprise Portfolio Architecture as the discipline develops and expands.

Certification, Licensing and Governance provide the mechanisms through which the canonical architecture, authorised use and continued stewardship of the discipline are maintained.

Ecosystem

The Ecosystem extends Enterprise Portfolio Architecture through the organisations and communities that support its application, capability and continued development.

It connects Advisory Support, Education & Learning Support, Technology Support and Ecosystem Participation around one canonical architectural foundation.

One Connected Architecture

Together, these components establish the enduring architecture through which Enterprise Portfolio Architecture can be interpreted, established and sustained across different enterprise environments
