چکیده:
It is obvious that the success of a project-based organization is dependent on its projects. A variety of tools such as the project excellence model, project management maturity models, the earned value method, have been developed in this regard, but there are still delays in projects because the projects have dynamic nature with non-linear relationships and feedback processes during the project life cycle. In this paper, we study the factors affecting the project management system in a project-based organization through system dynamics methodology and investigate the causal relations between them as well as the average cost and time variation of organizational projects during the time period. According to the analyses, the increase in each of the project quality or human resource efficiency is insufficient by raising the level of project management maturity or leadership maturity, but their concurrent increase and created synergy have a significant impact on the cost and time variation control. Furthermore, this research is contrary to the public perceptions under which the progress of projects depends on their funding. It is probably due to the maturity level of project management and the maturity of its leadership who takes measures for better management of costs and delays

In this paper, we study the factors affecting the project management system in a project-based organization through system dynamics methodology and investigate the causal relations between them as well as the average cost and time variation of organizational projects during the time period.
According to the analyses, the increase in each of the project quality or human resource efficiency is insufficient by raising the level of project management maturity or leadership maturity, but their concurrent increase and created synergy have a significant impact on the cost and time variation control.
(Shakibayifar, Hassannayebi, & Mirzahossein, 2018) It has become a widely recognized and flexible cause and effect methodology for modeling and simulating the dynamic environment of projects via the 13 analysis of delay and disruption in the system [ (Gholizad, Ahmadi, & Hassannayebi, 2017).
Definition of different scenarios; evaluation, selection, and implementation of appropriate solution Model Dynamic Hypothesis and Causal Model In project-based specialized parent organizations, the levels of relationship between parent organization as the employer with executives, and the amount of delegated authority for them in performing the projects, and the internal structures of work, and financial and strategic controls play significant roles in efficiency of executive organizations and timely implementation of projects within the framework of target objectives.
In this case, the time andA Systems Dynamics Model for Project Management systems of Project-Based Organization Abdolmehdi Salehizadeh, Jaffar Mahmudicost variations are above the acceptable levels, and thus the cost and time of projects will be dramatically increased.
