Internal team challenges are the concerns of most engineering project managers who struggle during the project’s progress. Most managers agreed that System Dynamics (SD) modeling could help with internal team problems; however, most project managers detest SD modeling because of its complexity, particularly when they don’t have the necessary computation, software development, IT, or engineering skills. The study analyzed internal team concerns using experimental and literature review approaches. Literature review results from studies show that 78.3333% to 95% of project managers find it difficult to deal with internal team issues. Managers may utilize SD to apply mathematical skills to internal team difficulties, as evidenced by a range of 78.3333% to 95.3%; however, developing an SD model lacking programming and mathematical analytics knowledge is challenging. In response to these difficulties, the authors developed a model SD model that may assist managers in resolving issues on internal team obstacles.
