Key Challenges of System Dynamics Implementation in Project Management

System dynamics can fail to make an impact in projects, particularly due to challenges in the implementation phase. Ensuring successful implementation is therefore essential. This can be done by first identifying the implementation challenges. By conducting expert validation sessions, this paper suggests that the challenges are due to lack of understanding and trust in the model itself. Eleven root causes of these challenges are identified by applying Ishikawa's fishbone method. They can be categorized into three main categories: mental model shifting, engaging stakeholders and leading changes, and explaining and credibly implementing the model. These are all related with managing people.
