Chapter 5 Activity-Based Management and
Activity-Based Costing
2
Learning Objectives (1 of 2)

• Identify the focus of activity-based management
• Explain why non-value-added activities cause
  costs to increase unnecessarily
• Explain why cost drivers are designated in
  activity-based costing

3
Learning Objectives (2 of 2)

• Contrast activity-based costing to the
  traditional cost accounting system
• Describe the types of information provided by an
  activity-based costing/management system
• Explain when it is appropriate to use
  activity-based costing

4
Activity-Based Management

• Focuses on activities during production and
  performance process
• Improves the value received by customers
• Enhances profitability

5
Activity

• An activity is a repetitive action performed in
  fulfillment of a business function

7
Activity Based Management

• External Benefits
• Increased customer value
• Enhanced profitability
• Internal Benefits
• More efficient production
• More accurate cost determination
• More effective performance evaluation

8
Activity Analysis

• Non-value-added activity
• Increases time spent on product or service but
  does not increase worth
• Unnecessary from customer perspective
• Can be reduced, redesigned or eliminated without
  affecting market value or quality
• Business-value-added activities are essential

• Value-added activity
• Increases worth of product or service to a
  customer
• Customer is willing to pay for it

9
Cost Driver Analysis

• Cost drivers are factors that have a direct
  cause-effect relationship to a cost
• Limit the number of cost drivers
• Cost of measurement should not exceed benefit of
  using the cost driver
• Easy to understand
• Directly related to activity being performed
• Appropriate for measurement

10
Cost Driver Analysis

• Unit-level costs
• direct material, direct labor
• Batch-level costs
• setup, inspection
• Product/process-level costs
• engineering changes, product development
• Organizational or facility costs
• building depreciation, plant managers salary

11
Activity-Based Costing

• Recognizes several levels of costs
• Accumulates costs into related cost pools
• Uses multiple cost drivers to assign costs to
  products and services

12
Two-Step Allocation

• Collect costs in general ledger and subsidiary
  accounts
• Identify activity centers
• Accumulate costs into activity center cost pools
  cost drivers
• Allocate costs to products and services
• activity driver measures demands placed on
  activities, thus, the resources consumed by
  products/services

13
Traditional vs. ABC Costing

• When ABC implemented
• Cost reduced for high volume, standard products
• Cost increased for low-volume, complex specialty
  products

14
Use ABC Costing when.

• Product Variety and Process Complexity
• Caused by mass customization
• Too many choices, opportunity for errors
• Pareto Principle
• Commonality of parts
• Reduced by
• Simultaneous (or Concurrent) Engineering
• Design for Manufacturability

15
Use ABC Costing when.

• Lack of Commonality in Overhead Costs
• - Some products/services use substantially
  more overhead than others
• Problems with Current Cost Allocations
• - Significant changes in process with no
  change in cost allocations
• - Expense majority of period costs when
  incurred

16
Use ABC Costing when.

• Changes in Business Environment
• Increase in competition
• Change in management strategy

17
Continuous Improvement

• Eliminates non-value-added activities to reduce
  cycle time
• Makes products/performs services with zero
  defects
• Reduces product costs on an ongoing basis
• Simplifies products and processes

ABC Costing Supports Continuous Improvement
18
Criticisms of ABC

• Significant amount of time and cost to implement
• Must overcome barriers to change
• Does not conform to GAAP
• May not promote total quality management

19
Advantages of ABC and ABM

• Identify and monitor significant technology costs
• Trace technology costs directly to products
• Identify the cost drivers that create or
  influence cost
• Identify activities that do not contribute to
  perceived customer value

20
Advantages of ABC and ABM

• Illustrate the impact of new technologies on all
  elements of performance
• Translate company goals into activity goals
• Analyze the performance of activities across
  business functions
• Analyze performance problems
• Promote standards of excellence

Questions

• What are the differences between activity-based
  costing and traditional cost accounting?
• What are cost drivers and activity drivers?
• What are two advantages and two criticisms of
  activity-based costing?
