Connecting Enterprise Architecture and Project Portfolio Management: A Review and a Model for IT Project Alignment

Abstract

Enterprise architecture (EA) and project portfolio management (PPM) are key areas when it comes to connecting enterprise strategy and information technology (IT) projects. Both management disciplines enhance business capabilities, integrate skilled resources, and govern affiliated processes and functions. A skillful comprehension of the links between these managerial areas is essential for effective IT planning. This article elaborates on the common grounds and structural attachment of EA and PPM, showing the substantiated relations between them and demonstrating their cohesiveness. From strategic planning to solution delivery, a conceptual model for IT project alignment integrates these IT management disciplines over two levels. EA ascertains the technical goals and constraints, whereas PPM determines the organizational goals and constraints. The results from both sides are combined to jointly propose, select, prioritize, and schedule IT projects. Roadmapping is a suitable approach to bring EA and PPM together.
