1. 1 Activity-Based Costing Better Costing for Better Decisions

2. 2 Indirect Costs Not easily and conveniently traceable to cost objects  Cost element is shared among cost objects  Physically impossible to trace  Not cost effective to trace

3. 3 Indirect Costs Need for allocation  Estimate product or activity cost What does it really cost?  Increase awareness of indirect costs Activities are not free  Plan more cost efficient operations Now that we know what it costs, what should we do?

4. 4 Allocation of Indirect Costs Typical allocation methods  Ability to bear  Fairness or equity  Benefits received  Cause and effect

5. 5 Traditional Allocation Method Indirect costs allocated to cost object based on the cost object’s consumption of some measure of activity, usually labor hours $10,000,000 total indirect cost 400,000 total labor hours = $25 per hour rate A product consuming 6 labor hours would be charged $150 of indirect costs

6. 6 Criticisms of Traditional Overhead Allocation Assumes all overhead is volume-related Factory-wide or departmental rates  All related to single activity measure Departmental focus, not process focus Focus on costs incurred, not cause of costs

7. 7 Activity-Based Costing Purpose  Allocation of indirect costs based on causal activities Attempts to identify “direct” link between cost and cost object  Results in better allocation  Does not provide “true” cost

8. 8 Activity-Based Costing Traditional allocation method Activity-based allocation method CostsProducts CostsProductsActivities First stageSecond stage

9. 9 Overview of ABC Identifies activities required to produce the product or service Determines the cost of the activities Allocates costs to the cost object based on the object’s consumption of activities

10. 10 Levels of Cost Incurrence Not all costs are volume-related  Unit level  Batch level  Product level  Facility level

11. 11 Operation of an ABC System Assign costs to activity pools  First stage allocation  Identify the costs incurred to perform various activities Determine the measure of activity best related to each cost pool  Cost drivers

12. 12 Operation of an ABC System Determine rate per unit of activity Assign costs to products/services based on consumption of activities  Second stage allocation Indirect costs are converted to direct costs

13. 13 Implementing ABC Step 1 – Plan the system  What are the goals? Inventory valuation Process improvement  Foster active involvement  Assemble cross-functional team Functional specialists

14. 14 Implementing ABC Step 2 – Define, analyze activities and resources  Decompose organization into elemental activities Who does what, and why?  Interview employees  Determine resources  Determine inputs and outputs

15. 15 Implementing ABC  Gather statistics on activities Inputs and outputs Transaction, duration, intensity For possible use as second-stage cost drivers

16. 16 Implementing ABC Step 3 – Establish activity cost pools and determine first stage allocation  First stage allocations assign costs to cost pools Requires costs to be re-categorized according to why they are incurred, not by type Drivers may be employee time, square footage, etc.

17. 17 Implementing ABC Step 4 – Determine second stage drivers and assign costs to cost objects  Outputs of activity analysis may be second stage drivers Distance moved, times handled, machine hours, units, etc.  Amount assigned to the cost object is the amount of activity consumed times the rate per unit of the activity

18. 18 When is ABC Most Useful? High amounts of overhead cost Multiple products Complex products Complex production system Significant variation in volume between high and low volume products

19. 19 When is ABC Most Useful? Different products place different demands on resources Problems with current cost allocations due to changes in products or processes Better cost information is needed

20. 20 Activity-Based Management Natural extension of ABC  Why are activities performed? Are they necessary? Are they consistent with organizational goals?  How are they performed? Are they performed efficiently? Can they be redesigned or eliminated?

21. 21 ABM for Process Improvement Focus on problems, opportunities Prioritize opportunities for improvement  Most critical  Greatest potential for cost savings

22. 22 ABM for Process Improvement Determine and explain causes for problems and opportunities  Cannot improve the system without first understanding it Select specific improvement projects

23. 23 ABM for Process Improvement Use ABC/ABM data to test potential impact of changes Make changes Iterate  Process of continual improvement

24. 24 Implications of ABC/ABM Shifts focus from managing costs to managing activities Aids in recognizing, measuring and controlling complexity Promotes understanding of why costs are incurred Provides better cost allocation information

25. 25 Implications of ABC/ABM Useful for planning future operations Fosters continuous improvement Likely to meet with substantial resistance  Analysis of why and how activities are performed
