This case study examines the implementation of the Activity-Based Costing (ABC) model at Evolution Mining Ltd, a gold mining company in Australia and New Zealand. The ABC model is a cost accounting method that assigns costs to activities and then allocates those costs to products or services based on the activities consumed. The study explores the benefits of using the ABC model, including improved cost allocation, more accurate pricing, and better decision-making. It also discusses the challenges of implementing the ABC model and provides recommendations for successful implementation.
