Enterprise Portfolio Architecture

Connected by Design

Connecting the Continually Evolving Enterprise

Enterprise Evolution is continuous. As organisations progressively evolve, they can become more fragmented. Maintaining coherence, continuity and connected understanding becomes increasingly difficult. We believe continually evolving organisations deserve an enduring enterprise discipline dedicated to helping organisations continually understand, plan and evolve the enterprise. EPOSA Institute exists to establish, advance and steward Enterprise Portfolio Architecture as that discipline.

What Is Enterprise Portfolio Architecture?

Enterprise Portfolio Architecture (EPA) establishes the enduring enterprise structures and connections through which organisations maintain coherence, continuity and connected understanding as they continually evolve.

The Enterprise Portfolio Operating System (EPOS) operationalises these structures, enabling the Enterprise Portfolio to be continually planned, prepared, executed and interpreted.
