Lean Manufacturing: A Comprehensive Guide for Businesses

Managing production costs efficiently is critical for businesses, especially in industries like Fast-Moving Consumer Goods (FMCG), where margins are often tight, and competition is fierce. Traditional costing methods may fall short in providing the nuanced insights needed for accurate cost allocation, particularly when a factory produces multiple diverse products. This is where Activity-Based Costing (ABC) comes into play as a game-changer for overhead cost distribution.

 

What Is Activity-Based Costing (ABC)?

Activity-based costing is a costing methodology that assigns factory overhead costs to products or services based on the activities required to produce them. Unlike traditional methods, which often allocate costs based on a single metric like labor or machine hours, ABC uses activity drivers that reflect resource consumption more accurately.

In an FMCG factory, products like snacks, beverages, and personal care items have varying production requirements. ABC ensures that each product bears its fair share of costs, based on its unique resource usage.

 

Challenges in Overhead Cost Distribution in FMCG

In FMCG production, overhead costs include indirect expenses such as:

• Factory rent
• Utility bills
• Machinery maintenance
• Quality assurance processes
• Packaging and logistics

Given the diversity of products in an FMCG factory, traditional costing methods often fail to capture the specific demands each product places on these resources. This can lead to:

• Overcosting low-resource products, making them seem less profitable.
• Undercosting high-resource products, leading to hidden inefficiencies.

 

 

 

How ABC Works for FMCG Overhead Cost Distribution

1. Identify Activities
The first step in ABC is to break down the production process into distinct activities. In an FMCG factory, this might include:

• Procurement and handling of raw materials
• Machine setup for production runs
• Production line operations
• Quality checks and assurance
• Packaging and labeling

2. Assign Costs to Activities

Each activity is associated with a share of the total overhead costs. For example:

• Utility bills may be linked to machine hours.
• Maintenance costs could depend on the frequency of equipment usage.
• Quality checks might vary based on the complexity of the product.

3. Determine Cost Drivers

Cost drivers are the factors that influence the cost of each activity. Common examples include:

• Machine hours used for production.
• Number of setups for switching product lines.
• Volume of units packaged.
• Number of quality inspections conducted.

4. Allocate Costs to Products

Using the identified cost drivers, overhead costs are distributed to individual products. Products that require more machine time, frequent setups, or specialized quality checks will bear a higher share of the overhead.

 

Benefits of Using ABC in FMCG Production:

1. Accurate Cost Allocation

ABC ensures that products are charged only for the resources they actually consume. This precision helps avoid cross-subsidization, where one product unfairly bears the costs of another.

2. Informed Pricing Strategies

With a clearer understanding of product-specific costs, managers can set prices more strategically, ensuring competitiveness without sacrificing profitability.

3. Operational Efficiency

By revealing high-cost activities, ABC highlights opportunities for cost reduction and process improvement. For example, frequent setup costs may signal the need for batch production adjustments.

4. Improved Product Mix Decisions

ABC provides insights into which products are truly profitable and which might be draining resources. This enables better decisions about product portfolio optimization.

 

Example: ABC in an FMCG Factory:

Imagine a factory producing two products: bottled water and a carbonated drink. Using traditional costing, overheads might be allocated based on production volume, making both products seem equally expensive. However, with ABC:

• The carbonated drink requires more frequent machine setups, complex quality checks, and additional packaging steps.
• Bottled water, being simpler to produce, consumes fewer resources.

ABC would assign a higher share of overheads to the carbonated drink, reflecting its true cost. This helps the factory make informed pricing or process adjustments.

 

Challenges of Implementing ABC:

While ABC offers significant advantages, it does come with some challenges:

• Complexity: Identifying and measuring cost drivers can be time-intensive.
• Data Collection: Accurate data is critical, requiring robust systems and tools.
• Implementation Costs: Initial investment in ABC can be high, though the long-term benefits typically justify the expense.

 

Real-Life Example of Activity-Based Costing: Bottled Water vs. Carbonated Drink:

To illustrate how Activity-Based Costing (ABC) works in practice, let’s consider a factory that produces two products: bottled water and a carbonated drink. Both products share the same production facility, but their production processes differ in complexity and resource consumption.

 

 

Factory Overview

• Bottled Water: A straightforward product requiring basic filtration, bottling, and labeling.
• Carbonated Drink: A more complex product involving flavor mixing, carbonation, bottling, and advanced packaging.

The factory incurs the following annual overhead costs:

Particulars	Amount
Quality Control	100,000
Machinery setup	80,000
Packaging & labelling	120,000
Utility costs	60,000
Total Overhead Costs	360,000

 

The factory uses ABC to distribute these overhead costs between bottled water and carbonated drink production.

Step 1: Identify Activities and Cost Drivers

 

Activity	Cost Driver	Overhead Costs (AMT)
Quality Control	Number of Inspection	100,000
Machinery Setup	Number of Setup	80,000
Packaging and Labelling	Number of bottles packed	120,000
Utility usage	Machine hours used	60,000

 

Step 2: Data Collection

    Annually production Details:

Products	Number of bottles produced
Bottled Water	200,000
Carbonated Drink	150,000

 

    Cost Driver Usage:

   

Activity	Bottled Water	Carbonated Drink
Quality Control	100 inspections	200 inspections
Machinery Setup	20 setups	60 setups
Packaging	200,000 bottles	150,000 bottles
Machine hours	1,500 hours	2,500 hours

           

Step 3: Calculate Activity Rates

The activity rate is calculated by dividing the total cost of each activity by the total usage of its cost driver.

Activity	Total Cost	Total Cost Driver unit	Activity Rate
Quality Control	100,000	300 Inspections	333.33	Per inspection
Machinery setup	80,000	80 setups	1,000.00	Per setup
Packaging	120,000	350,000 bottles	0.34	Per bottle
Utility usage	60,000	4,000 machine hours	15.00	Per machine hour

 

Step 4: Assign Costs to Products

Bottled Water Overhead Costs:

Activity	Cost Driver	Activity Rate	Cost of Activity
Quality Control	100 inspections	333.00	33,333
Machinery setup	20 setups	1,000.00	20,000
Packaging	200,000 bottles	0.34	68,000
Utility usage	1,500 hours	15.00	22,500
Total Overhead for bottled water			143,833

 

Carbonated Drink Overhead Costs:

Activity	Cost Driver	Activity Rate	Cost of Activity
Quality Control	200 inspections	333.00	66,667
Machinery setup	60 setups	1,000.00	60,000
Packaging	150,000 bottles	0.34	51,000
Utility usage	2,500 hours	15.00	37,000
Total Overhead for Carbonated Drink			215,167

 

Step 5: Analyze Results:

Product	Overhead Costs	Production Volume	Overhead Cost per Unit
Bottled Water	$143,833	200,000 bottles	$0.72 per bottle
Carbonated Drink	$215,167	150,000 bottles	$1.43 per bottle

 

Insights from ABC:

1. Carbonated Drink Is Costlier:

The carbonated drink has a higher overhead cost per unit because it consumes more resources—frequent quality checks, more machinery setups, and higher utility usage for complex production processes.

2. Strategic Pricing:

With precise cost data, the factory can set a higher price for carbonated drinks to reflect their true production costs while keeping bottled water competitively priced.

3. Operational Efficiency:

Identifying costly activities like frequent setups and quality checks provides opportunities to streamline processes, such as optimizing batch sizes or improving quality standards.

 

Conclusion

This example highlights how Activity-Based Costing (ABC) enables more accurate overhead cost allocation, especially in a multi-product factory like FMCG. By understanding the true cost of each product, managers can make data-driven decisions about pricing, product mix, and process improvements, ultimately enhancing profitability and operational efficiency.
