Given that CoPS development projects are costly, failing to conduct them will ruin the organization. Therefore, the decision to out/in source them, is important. In this paper, the factors influencing this decision are discussed. Employing the Fuzzy Delphi method, the indices are utilized to develop the SEM model. The results s how three dimensions of t he “projects characteristics”, “requirements” and “competency”. Hypothese surge that projects characteristics have a significant effect on the requirements, which in turn have a similar effect on the competency. To compare, the ISM method was used. The results are quite similar to those of the SEM model. No sooner could organizations outsource such projects than they gain the technological, contractual, project control, integration, soft technologies, financial and communications strategies capability. The managers of organizations and companies developing CoPS such as airplanes power plants, express trains and ships can use the results and implications of this model.
