Historical Context
Activity dictionaries emerged as a critical tool with the development of Activity-Based Costing (ABC) in the 1980s. ABC was pioneered by Robert Kaplan and Robin Cooper to provide more accurate cost information by identifying the true drivers of costs within organizations.
Types/Categories
An activity dictionary typically categorizes activities into several groups:
- Unit-Level Activities: Performed each time a unit is produced.
- Batch-Level Activities: Carried out whenever a batch of products is processed.
- Product-Level Activities: Related to specific products.
- Customer-Level Activities: Conducted to serve specific customers.
- Organizational-Level Activities: Sustains the organization as a whole.
Key Events
- 1987: Publication of Robert Kaplan and Robin Cooper’s works introducing ABC.
- 1990s: Widespread adoption of ABC in various industries.
- 2000s-Present: Continuous improvement and integration with Enterprise Resource Planning (ERP) systems.
Detailed Explanations
Defining Activities
An activity dictionary provides precise definitions of activities. For instance:
- Assembling: Joining various parts to form a product.
- Quality Testing: Evaluating the product’s compliance with quality standards.
- Customer Service: Handling customer inquiries and complaints.
Mathematical Models and Formulas
In ABC, the cost of each activity is allocated to products or services based on their consumption of these activities. The formula used is:
For example, if the total cost of the quality testing activity is $10,000 and the total number of quality tests conducted is 500, then:

Importance and Applicability
- Cost Management: Helps in identifying the true cost of products or services.
- Resource Allocation: Facilitates more effective allocation of resources.
- Decision Making: Provides accurate data for strategic decisions.
Examples
- A manufacturing company uses an activity dictionary to track the cost associated with machine setups, maintenance, and inspections.
- A service firm uses an activity dictionary to allocate costs related to client meetings, report generation, and consultation hours.
Considerations
- Complexity: Implementing and maintaining an activity dictionary can be complex and resource-intensive.
- Data Accuracy: Requires precise and up-to-date data for effectiveness.
Related Terms with Definitions
- Activity-Based Costing (ABC): A costing method that identifies activities and assigns costs to products/services based on their consumption.
- Cost Driver: Any factor that causes a change in the cost of an activity.
- Cost Object: Anything for which a separate measurement of costs is desired.
Comparisons
- Traditional Costing vs. ABC: Traditional costing assigns overhead costs based on a single cost driver, whereas ABC uses multiple cost drivers for more accuracy.
Interesting Facts
- ABC originated in manufacturing but has found applications in healthcare, telecommunications, and service industries.
- Many large companies, including General Electric and Procter & Gamble, have adopted ABC and activity dictionaries for cost management.
Inspirational Stories
- General Motors: Successfully implemented ABC to identify and eliminate inefficiencies, leading to substantial cost savings and improved profitability.
Famous Quotes
- “You can’t manage what you don’t measure.” - Peter Drucker
Proverbs and Clichés
- “The devil is in the details.” - Emphasizing the importance of detailed activity tracking.
Expressions, Jargon, and Slang
