Business Process Architecture (BPA) and Enterprise Architecture (EA) require integration to serve as effective management tools. Prior literature reviews have not focused on EA-BPA integration. This work aims to fill this gap by conducting a literature review analyzing and comparing how EA approaches include and consider BPAs. We found most related research that analyzed EA approaches recognize the need of integrating business processes with multiple organizational aspects but do not provide a standalone BPA viewpoint nor offer specific integration guidelines. The article concludes by identifying criteria for adopting an EA approach and highlighting research gaps that suggest the EA-BPA integration field remains largely unexplored and open to further inquiry.
