Inc. allocates substantial resources to quality control activities. They identify
inspection, testing, and compliance checks as activities that contribute
significantly to their overall production costs. Ensuring that every component
meets stringent safety and quality requirements is a priority.
Step #2. Assigning overhead costs to the activities identified in step 1,
In the case of Precision Parts Inc., after identifying the critical activities, the
next step in implementing activity-based costing (ABC) is allocating overhead
costs to each of these activities.
Overhead Costs Breakdown
Precision Parts Inc. conducts a detailed review of their annual expenses. They
determine that machine maintenance costs amount to $300,000, while
quality control expenses total $200,000 for the year. These costs are
categorized as overhead expenses.
Assigning Costs to Activities
Precision Parts Inc. proceeds to allocate these overhead costs to the specific
activities identified in step 1, which, in this case, are machine maintenance
and quality control.
Activity Estimated annual Overhead Cost
Machine Maintenance $300,000
Quality Control $200,000
Total $500,000
Step #3. Identifying the cost driver for each activity
Another crucial phase involves the identification of cost drivers specific to
each activity. To illustrate this, let's focus on our two activities, machine
maintenance and quality control, For machine maintenance, a pertinent cost
driver could be the number of machine hours utilized throughout the year,
which, in this instance, amounts to 2,000 hours. In contrast, quality inspection
costs may be closely correlated with the number of inspection checkpoints
conducted during production, resulting in a cost driver represented by the
count of these inspections (Heisinger & Hoyle, 2012)
Step #4. Identifying the cost driver for each activity
Another significant stride in the process entails identifying the specific cost
drivers for each activity. To illustrate this, let's delve into our two activities:
machine maintenance and quality control. For machine maintenance, a
pertinent cost driver can be discerned in the form of the number of machine
