This assignment delves into the realms of project management efficiency, focusing on enhancing cost-efficiency based on a study published in the Journal of Intelligent Manufacturing. The primary objective is to analyze and implement improvements to project supervision costs using time-driven activity-based costing (ABC), as proposed by Yang and Hao. By examining the learning curve approach outlined in their paper, students will gain insights into evaluating and enhancing cost-efficiency based on real-world data and methodologies.
