Design and management of software development projects under rework uncertainty: a study using system dynamics

Despite proper planning and scheduling, project execution is challenging, and one critical factor is uncertainty during the project implementation process. This study presents a system dynamics (SD) model as a decision-support system for model-based decision-making that considers the uncertainty of rework generation by predicting dynamic and complex project behaviour. The SD model was developed along with a rework cycle that principally contributes to rework generation. The uncertainty of rework generation and project performance were visualized and integrated into decision-making components. Six different scenarios involving hiring and overtime usage were explored to ensure project performance when designing a feasible project plan.The novelty of this study lies in the decision-making process for obtaining the best planning alternatives under uncertainty and project conditions. Actions should be implemented that predict and analyse improvised project planning processes and control model-based decision-making under uncertainty.
