Management accounting uses different costing and performance measurement methodologies to support planning, cost control, decision-making, and enterprise optimization. These methodologies help managers improve operational efficiency and allocate costs more accurately.

1. Activity-Based Costing (ABC)

Meaning

Activity-Based Costing (ABC) is a costing method that assigns costs to products or services based on the activities that consume resources.

ABC was first clearly defined in 1987 by Robert S. Kaplan and W. Bruns in their book Accounting and Management: A Field Study Perspective.

Need for ABC

ABC was developed because technological advancements and automation changed the cost structure of manufacturing industries.

Earlier, direct labour and direct material formed the major portion of production costs. However, increased automation reduced direct labour costs while increasing indirect costs, such as depreciation.

ABC helps allocate these indirect costs more accurately by identifying the activities responsible for incurring them.

Key Exam Points

ABC = Activity-Based Costing.
Introduced by Robert S. Kaplan and W. Bruns.
Clearly defined in 1987.
Assigns costs based on activities.
Suitable where indirect costs are significant.

2. Grenzplankostenrechnung (GPK)

Meaning

Grenzplankostenrechnung (GPK) is a German costing methodology developed between the late 1940s and the 1960s.

The objective of GPK is to provide a consistent and accurate method for calculating and assigning managerial costs to products and services.

The term Grenzplankostenrechnung is commonly translated as:

Marginal Planned Cost Accounting, or
Flexible Analytic Cost Planning and Accounting

Development of GPK

The development of GPK is credited to:

Hans Georg Plaut (Automotive Engineer)
Wolfgang Kilger (Academic)

Their objective was to improve the accuracy and usefulness of management cost accounting information.

GPK is widely taught in German-speaking universities.

Key Exam Points

GPK = German Costing Methodology.
Developed during the late 1940s–1960s.
Developers:
- Hans Georg Plaut
- Wolfgang Kilger
Focuses on accurate managerial cost allocation.

3. Lean Accounting

Meaning

Lean Accounting is an accounting approach designed for organizations implementing the principles of the Lean Enterprise or the Toyota Production System (TPS).

The concept of Lean Accounting emerged during the mid-to-late 1990s.

Traditional accounting methods were considered more suitable for mass production, whereas Lean Accounting supports Just-in-Time (JIT) manufacturing and lean business operations.

Development

The Lean Accounting movement gained significant attention during the Lean Accounting Summit (2005) held in Dearborn, Michigan, USA.

The summit discussed the advantages of adopting accounting practices that support lean manufacturing.

Key Exam Points

Developed during the mid-to-late 1990s.
Supports Lean Enterprise and Toyota Production System.
Suitable for Just-in-Time (JIT) manufacturing.
Lean Accounting Summit (2005) was held in Dearborn, Michigan, USA.

4. Resource Consumption Accounting (RCA)

Meaning

Resource Consumption Accounting (RCA) is a modern management accounting methodology that provides managers with information for enterprise optimization and decision-making.

RCA is defined as a dynamic, fully integrated, principle-based, and comprehensive management accounting approach.

Development

RCA emerged around 2000 and was further developed by CAM-I (Consortium for Advanced Manufacturing–International) through its Cost Management Section RCA Interest Group in December 2001.

Key Exam Points

RCA = Resource Consumption Accounting.
Emerged around 2000.
Developed by CAM-I.
Provides decision support information.
Focuses on enterprise optimization.

5. Throughput Accounting

Meaning

Throughput Accounting is a modern management accounting technique that focuses on improving the overall performance of the organization by recognizing the interdependence of production processes.

It measures the contribution earned per unit of constrained resource for a product, customer, or supplier.

The objective is to maximize the efficient use of the organization’s limiting resources.

Key Exam Points

Focuses on constrained resources (bottlenecks).
Measures contribution per unit of constrained resource.
Supports optimization of production performance.

6. Transfer Pricing

Meaning

Transfer Pricing is a management accounting technique used to assign value, costs, and revenue among different business units of the same organization.

Although commonly used in manufacturing, it is also widely applied in the banking industry.

Transfer Pricing in Banking

In banks, transfer pricing is mainly used to allocate the interest rate risk among different business units.

The Corporate Treasury Department performs this allocation.

Business units that use bank funds (such as lending departments) are charged funding costs.
Business units that generate funds (such as deposit departments) receive funding credits.

This process is known as Funds Transfer Pricing (FTP).

Transfer pricing helps business units prepare segment-wise financial results, which are useful for evaluating performance.

Key Points

Transfer Pricing allocates costs and revenues among business units.
Widely used in manufacturing and banking.
In banking, it allocates interest rate risk.
Managed by the Corporate Treasury Department.
Business units prepare segment financial results after transfer pricing adjustments.

Comparison of Major Methodologies

Methodology	Main Purpose	Key Focus
Activity-Based Costing (ABC)	Accurate cost allocation	Activities as cost drivers
GPK	Managerial cost allocation	Planned and flexible costing
Lean Accounting	Support lean manufacturing	Just-in-Time production
Resource Consumption Accounting (RCA)	Enterprise optimization	Resource consumption
Throughput Accounting	Improve production performance	Constrained resources
Transfer Pricing	Internal cost and revenue allocation	Business unit performance

Key Points

ABC was defined in 1987 by Robert S. Kaplan and W. Bruns.
ABC allocates costs based on activities rather than direct labour.
GPK is a German costing methodology developed between the late 1940s and the 1960s.
GPK was developed by Hans Georg Plaut and Wolfgang Kilger.
Lean Accounting supports the Toyota Production System and Just-in-Time manufacturing.
The Lean Accounting Summit (2005) was held in Dearborn, Michigan (USA).
RCA emerged around 2000 and was developed by CAM-I.
Throughput Accounting measures contribution per constrained resource.
Transfer Pricing allocates costs and revenues among business units.
In banking, Transfer Pricing is used to allocate interest rate risk and prepare segment financial results.
