This report provides an analysis of two articles focusing on the application and relevance of managerial accounting systems (MAS) in contemporary business environments. The first article examines a multinational manufacturing company's implementation of a modern MAS, evaluating the relevance and usefulness of techniques like Just-in-Time (JIT), Value Chain Analysis (VCA), and Total Quality Management (TQM). The report highlights the challenges faced and the limited practical application of these systems. The second article explores the implementation of Activity-Based Costing (ABC) in an Australian farm, discussing its effectiveness in overcoming traditional costing system barriers. The report compares and contrasts the findings, concluding that the relevance of MAS depends on factors such as communication, the presence of computerized accounting systems, and the consideration of implementation barriers. The report emphasizes the importance of aligning MAS with specific business needs for effective decision-making.
