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

Abstract

Despite proper planning and scheduling, project execution is challenging, and one critical factor is uncertainty duringthe 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 developedalong with a rework cycle that principally contributes to rework generation. The uncertainty ofrework generation and project performance werevisualized and integrated into decision-making components.Six different scenarios involving hiring and overtime usage were explored to ensure project performance whendesigning a feasible project plan.The novelty of this study lies inthe decision-making process for obtaining the best planning alternatives under uncertainty and project conditions. Actions should be implemented thatpredict and analyse improvised project planningprocesses and control model-based decision-making under uncertainty.
