Project-based organizations (PBOs) are loosely coupled, with significant decentralization of power that makes complex the alignment of projects, governance system and functional units. Moreover, projects are constantly changing in a PBO. Therefore, a solution for PBO design and analysis is needed to provide cohesion of a single design in constant remapping. Designing a PBO involves aligning strategy, structure, processes, organizational behaviour and people, as well as the project management (PM) practices and artefacts. However, the available tools to achieve this goal do not have an integrated overview between the organization and PM. Also, they are mainly in the form of a text guideline that makes its application difficult. In order to fill this gap, this research seeks to develop an integration between project management and enterprise architecture domains. The above is performed through a conceptual integration of the ArchiMate language for modelling the organizational architecture and the PMBOK PMs' body of knowledge, providing an alternative tool for covering the PBO design, analysis and modelling concerns. This integrated model has been developed through the semantic web that enhances computer querying and reasoning for its analysis. An evaluation has been performed through automatic ontology debugger tools.
