Yes ABC be better suited for Wilkerson than Costing system
because :
- Activity-based costing allows tracing indirect costs to product
with a high degree of accuracy. While volume-based costing is
implicitly based on an assumption that there’s a direct
relationship between volume of production of individual products
and level of overhead, activity-based costing allows finding
individual relationships between volume of production and different
overheads
- It becomes possible due to combining overheads into cost pools
and allocating these cost pools to products in proportion to
selected cost drivers that reflect these individual relationships
between volume of production and level of overheads.
- Wilkerson should pool overheads into five groups (cost pools):
machine-related expenses, setup labor cost, receiving and
production control, engineering, packaging and shipment. The next
step is choosing most appropriate cost drivers that reflect the
relationship between volume of production of individual products
and level of overheads.
- Machine hours are the most natural cost driver for
machine-related expenses. Both setup and receiving, and production
control activities are changed in proportion to number of
production runs.
- Engineering cost can be allocated in proportion to hours of
engineering work, whereas packaging and shipment activity is driven
by the number of shipments.
- Activity-based costing provides more accurate information about
product cost and, therefore, their gross margins.
