Brimson, J. A. 1998. Feature costing: Beyond ABC. Journal of Cost Management (January/February): 6-12. Summary by Kellee Mundy |
This article discusses feature costing, which, according to Brimson, is becoming the
alternative to activity-based costing (ABC). Feature costing helps reduce
company cost and improve performance due to less data needed to create the
product cost.
Why
the Need for Feature Costing
Conventional overhead cost methods provided distorted cost because that data on
financial performance is received too late for errors to be corrected.
Also, the conventional method arbitrarily assigns managers with the responsibility of
accounting for cost that they have no control over. Activity-based
costing was developed to help improve the deficiencies of conventional overhead
costing. Unfortunately, activity-based costing can become so detailed and complex
that it is hard to create and maintain. Feature
costing provides the same great advantages of activity-based costing, yet it is
easier to use.
How
to Conduct Feature Costing
Step
1: Determine the Product Features
At this step, the features of each product are determined. A feature is a
major element of a product. The features of a product are then divided
into sub-features. This process continues until sub-features no longer vary.
In this article, a car was used as an example to show how to determine the features
of a car. The main feature of a car would be the engine. The engine
could then be classified into sub-features such as gas or diesel and number of cylinders.
Step
2: Determine the Activity Routing Associated with Each Product Feature
At this step, the working steps involved with the product features, established in step 1, are determined. The working steps are
the activities that are needed to make a feature of a product.
Step
3: Determine the Cost of Each Activity
At this step, the cost of each activity in step 2 is determined. The cost
of an activity can consist of "people, machines, travel, supplies, computer
systems…" that are involved with each activity (Brimson, 10). Also during this step, an
average activity cost is computed by doing an analysis of each activity.
This average activity cost will be used to compute the final product cost.
Step
4: Determine Product Characteristics that Will Cause the Process to Vary
At this step, product characteristics are determined. A product
characteristic gives the product its distinction. In the example of the car, some product
characteristics would be the number of doors and the color of the car. It
is then determined if these product characteristics will cause a variation
"such as additional work steps, longer processing time, and/or quality
problems"
(Brimson, 10).
Step
5: Determine How Much the Product Characteristics Cause the Process to Vary
At this step, the product characteristics determined in step 4 are considered to
see how much they will impact the product process. If the product characteristics will cause a loss, it needs to be determined how much of a
process loss will need to be added to the final product cost.
Step
6: Associate Features and Characteristics to Products
At this step, the features and characteristics that were determined in steps 1and 4 are associated back to their product.
Step
7: Adjust the Activity Cost Based on the Product’s Features and Characteristics
At this final step, the product cost is computed. All costs that were determined in the previous steps are added together to compute the final product
cost.
Advantages
of Feature Costing
This article lists several advantages of feature costing over the conventional overhead allocation method and activity based costing method. One
advantage is that feature costing uses the process management model. This model allows
for a better understanding of product costing. Another advantage of feature
costing is the ease of use over previous methods. This is due to the fact that
less data is needed to calculate the product cost. The last advantage is that
feature costing determines the factors that cause a variation to happen.
This allows for improvements to be made to the product process.
"Feature costing is a logical next step in the evolution".
