The Next Generation of ABCDevine et al., Management Accounting Quarterly Fall 2005 ACCT7320 Thanks to Ye Tian
Principles of ABC … • ABC arose in the 1980s. • In ABC costs are assigned according to 'cause and effect' relationship between activities (the actual process) and cost objects.
ABC Extension • The principles of activity-based costing can be extended to the allocation of assets to activities. • What’s the benefit? • Product ROI (PROI) • Customer ROI (CROI) measures • Necessary condition to use it: • An existing ABC system • Significant differences in asset utilization across • across customers • across product lines.
Case example:ABC at Parts For Carts • Company’s background: • Manufactures automobile parts • Two primary customers: • Automobile manufacturer (Customer 1) • After-market supplier of auto parts (Customer 2) • Two primary product lines: • “in house” (Product A) • “outside suppliers” (Product B)
Significant impact on PROI: • Product A places high demand on the capital-intensive fabrication activity and low demand on the packaging and warehousing/storage activities • Product B places low demand on the capital-intensive fabrication activity and high demand on the packaging and warehousing/storage activities
Significant impact on CROI: • Customer 1 places a high demand on both the highly capital-intensive fabrication and warehousing/storage activities. • Customer 2 places a low demand on these, and a high demand on the packaging activity (with just average capital intensity).
The impact of Product and Customer ROI on Decision Making • Outsourcing decision • Hmmm…..misleading?! • Better utilization of existing asset • Simplify existing product lines • Redesign the product and/or the manufacturing or distribution processes • Negotiate price with customers
Conclusions? • What do you think? • Useful? • Any flaws in the logic?
