Garrison and Noreen identify six core steps to ABC costing implementation.*

Step #1: Activity Identification

Step #2: Activity Analysis

Step #3: Assignment of Costs

Step #4: Calculate Activity Rates

Step #5: Assign Costs to Cost Objects

Step #6: Prepare and Distribute Management Reports

ABC costing does nothing for the organization if the information is collected but no action follows. The key to the value of this form of costing is that it is actionable. This analysis allows companies to make decisions about product lines, where to direct sales efforts, and to validate the true value provided by capital equipment.
