Relevance lost: the rise and fall of activity-based costing by: Nitza Geri & Boaz Ronen
A Critique After having been exposed on how activity-based costing works, I am wondering why it is not adopted by all of the companies. While it is true that the debate between the traditional cost system and the activity-based cost system seem to be endless, here is paper written by Nitza Geri and Boaz Ronen that introduces another concept and that is global decision-making methodology or GDM. Through their research and case study, they have seen that GDM is an effective alternative to costing methods, which improves the quality of decisions and enhances organization value.

They have laid down the stages, some diagrams and terms which give life to the entire concept. Although all these have helped me understand, they will just be a cause of headache. This is because the paper is becoming too technical. Articles are read to have a support to whatever there is in the books not additional eye stress. Good thing that the authors have given a case study to which GDM is being applied. It is
