Based on EA information, projects develop their results, called solutions, which possibly affect the EA model. As the interaction between projects and EA is not always coordinated, wrong decisions can be taken and, consequently, solutions can be developed that do not conform to the EA. Therefore, we propose an enterprise architecture roundtrip process that guides the coordinated and project-driven distributed evolution of an EA model.enEnterprise Architecture ManagementModel MergingEnterprise ArchitectureRoundtripEAMProject AlignmentDistributed EvolutionTowards an Enterprise Architecture Model EvolutionText/Conference Paper1617-5468
