Use of Time-driven Activity-based Costing (TD-ABC) in Allocating Joint Costs

This study aims to present the time-driven activity-based costing (TDABC) method as a modern method. It also aims to identify how to apply the time-driven activity-based costing (TDABC) method in allocating joint costs compared to other traditional costing systems through an analytical study of the problems of implementing traditional cost accounting systems. The study is based on a main hypothesis stating that "the use of a time-driven activity-based costing (TD-ABC) system improves the accuracy of allocating joint costs between products, which contributes to achieving greater fairness in cost distribution and increasing the efficiency of resource management compared to traditional methods." The descriptive approach was adopted in the theoretical aspect, while the analytical approach was adopted in the practical aspect. The researcher relied on data from the Zakho Dairy Factory for the year (2023) through interviews and field visits to the factory, the study sample. The study reached a number of conclusions, the most important of which is that the use of the time-driven activity-based costing (TDABC) method has a significant impact on the accurate allocation of joint costs.
