overhead to multiple activity cost pools,
Trang 12Activity : Any event, action, transaction, or work sequence that causes a cost to be incurred in
producing a product or providing a service.
Activity Cost Pool : The overhead cost attributed
to a distinct type of activity.
Examples:
Purchasing materials.
Setting up machines.
Cost Drivers : Any factors or activities that have

Stage 1 : Overhead costs are allocated to activity
cost pools.
Stage 2 : The overhead costs allocated to the cost pools is assigned to products using cost drivers.
The more complex a product’s manufacturing
operation, the more activities and cost drivers
likely to be present.

Analyze each operation or process, document and time every task, action, or transaction.
Know how companies identify and use cost drivers in ABC.
Cost drivers identified for assigning activity cost pools must:
Accurately measure the consumption of the activity.
Have related data easily available.

Enhanced control over overhead costs.
Better management decisions.
Trang 46Differentiate between value-added and non-value-added activities.
Value-added activities increase the worth of a product or service Non-value-added activities add cost to, or increase the time spent
on, a product or service without increasing its market value.
