Mesa, Manila, Philippines Abstract This research study focuses on project organization structure, multi-tasking, issues, challenges, and limitations that occur during the project execution for a conventional and virtual team. This research aims to understand the im- portance of the technical labor force in the organization and fill the human resources gap in project engineering, construction, and management imple- mentation. The project is unique and must be dealt with highly technical by the project team. Projects might be the same structure and scale but in dif- ferent conditions, parameters, and requirements. In general, dealing with and executing other projects is challenging. The design guidelines are formatted, although not entirely the same. The process model uses model-based opti- mization to compare the conventional and virtual MSS organizational struc- tures to optimize, innovate, and multi-tasking project staff, personnel, and direct technical members. The study will include the importance of global virtual teams (GVT) and the contribution of software collaboration, includ- ing cloud-based software (CBS). Multi structures-scales (MSS) concept can be a diversified, optimized, and innovative way to increase team effectiveness, technical dependence, and utilize existing resources. It uses organizational productivity and the individual living of project team members. However, even though the MSS concept seeks to lower the labor cost and reduce indi- vidual participation, the labor issue, technical workforce, challenges, disputes, and other problems are not inevitable. As a result, in this implementation, the corporate organization will solidify the project team structure into mul- ti-project execution even to long-term employment and operation. The PE/S can perform simultaneously in different stages of the same type of project. In contrast, a PM can perform additional steps even on other kinds of projects. Furthermore, in the study, PS and PM can effectively function if not more than three (3) projects; otherwise, low-performance evaluation and low-quality product results occur.
