This project examines the benefits of implementing the Activity Based Costing (ABC) Model for Magellan Fin Group Limited, an investment firm focused on maximizing investor returns. The ABC Model provides a more accurate and detailed approach to cost allocation compared to traditional methods, enabling the firm to identify and manage costs effectively. The project explores the features of the ABC Model, its alignment with Magellan Fin Group Limited's strategies, and its potential to improve cost control, decision-making, and overall profitability. Additionally, the project recommends the implementation of a Management Information System (MIS) to further enhance the company's performance by providing comprehensive and timely information for strategic planning and control.
