The project triad is a concept model of coordination that consists of three (3) leading project team players, such as the project client, consultant, and contractor, agreeing and embracing the transparency transaction in a virtual environment, that's virtual project coordination (VPC). The main objective is to fill in the gap, issues, and problems in communication, specifically in coordination and cooperation. Moreover, to prevent the duplication of ideas, increase competitiveness, and seek improvement for operational effectiveness in virtual project management (VPM). This literature review will gather data from publications, studies, technical papers, etc., from 2013 to 2023 publications. The project coordination depends on how effective communication is used in the project. Therefore, the review analysis focuses on project communication, coordination, cooperation, delivery, uses, tools, and techniques. Mostly related to the latest coordination issue that leads to disputes and how cooperative the project team is, including the virtual environment. The research review will use statistical analysis under the guidelines with the processes of the C4 model (collect, check, calibrate, and complete), filter, process, and sort the gathered data. Then, take the objective (optimization), significance (importance), evaluation, and limitation (OSEL) of the research publication. As a result, a statistical analysis is most likely mentioned in the related publication with coordination issues; however, the effectiveness will depend on the software collaboration used in the 5D model for the project. Therefore, the project triad concept is necessary for the project, whether simple or complex, with the collaboration of related software. The relevant topic's idea may be improved, optimized, and innovated to pursue this concept to realization and better application.
