It would not be worthwhile to further refine the cost system into an ABC system if (1) a single activity accounts for a sizable proportion of the department’s costs or (2) significant costs are incurred on different activities within a department, but each activity has the same cost driver or (3) there wasn’t much variation among contracts in the consumption of activities within a department. If, for example, most activities within the design department were, in fact, driven by design-hours, then the more refined system would be more costly and no more accurate than the department-based cost system.4. What value, if any, would CKM get by allocating costs of each department based on the activities done in that department?
