- XYZ Company produces and sells 2 products, Lambda and Gamma, and the production process goes through two departments. Traditionally Manufacturing Overhead (M/O) cost is applied on the basis of direct labor hours (DLH); estimated M/O cost is $ 5,757,500 and the estimated DLH is $12,250 for the most recent period.The team decided to replace traditional plantwide costing system to activity-based costing system.

This worked well until there was a problem which resulted in dangerous gases being released. The team of operators had great difficulty in finding the source of the problem and deciding what to do. Because they no longer have access to all the information, they have to spend time explicitly co-ordinating their understanding of the situation by talking to each other. Under the old system, the knowledge would be shared – one operator would know what was happening with another’s area of the plant without explicit communication. Although the team’s individual responsibilities would still have been clearly divided, the knowledge of the system would be shared. How could the new system of individual workstations be modified to make better use of distributed cognition?arrow_forward
