Ch. 19: Activity-Based Costing and Cost Management in Production and Operations

Production Departments

• Fabrication: This department is responsible for manufacturing individual parts or components of a product from raw materials. It involves processes like cutting, shaping, and forming materials. The output of this department serves as input for the assembly process.

• Assembly: This department combines the fabricated components and other purchased parts to create the final product. It involves various stages of putting parts together, often in a sequential manner, to ensure a functional and complete item.

Activities Required

• Activity Types:

  • Machine Hours: Represents the total time machines are actively used for production. This is a critical cost driver in highly automated fabrication departments, as machine operation incurs costs like electricity, maintenance, and depreciation.

  • Setups: Refers to the activities required to prepare machines or production lines for a new batch or product run. This includes changing tools, adjusting settings, and loading new programs. Each setup consumes time and resources, adding to the activity cost.

  • Inspections: Involves checking the quality of raw materials, in-process components, and finished products to ensure they meet specified standards. Inspections are essential for quality control and can be a significant cost driver if done frequently or if products require complex checks.

Cost Analysis

• The primary goal of this analysis is to accurately determine the total cost per unit for each product. This is crucial for pricing decisions, profitability analysis, and cost control. Using activity rates helps allocate indirect costs more precisely to products.

• All numerical calculations, especially those related to monetary values, must be rounded to the nearest cent ($0.01$) to maintain financial accuracy and consistency in reporting.

Spreadsheet Reference

• Title: Chapter 19, Class Examples

• Users should input relevant data specifically into the yellow-highlighted cells in the spreadsheet. These cells are designated for variable inputs to ensure the model’s flexibility and ease of use for different scenarios.

• It is imperative to ensure that all information, including activity levels, rates, and production volumes, is updated regularly to reflect current operational realities and provide accurate cost estimations.

Cost Calculation Process

• The process involves determining the activity cost per unit for each product by allocating indirect costs based on their respective activity drivers.

• Example of Elliptical: This demonstrates how indirect costs from the fabrication department are assigned.

  • Fabrication Rate: The rate for fabrication activities is $21$ per machine hour. This rate is derived by dividing the total budgeted fabrication cost by the total budgeted machine hours.

  • Total Fabrication Cost (Allocated) Calculation: The total cost allocated to the product for fabrication is determined by multiplying the machine hours consumed by that product by the established rate.

  • Total Fabrication Cost $=$ Machine Hours $\times$ Rate

  • Example: If the elliptical product consumed $1734$ machine hours, then:
    $Cost = 21 \times 1734 = 36,414$
    Correction based on previous output $21 \times 1734 = 36,414$ not $61,996$. The example should lead to the correct calculation consistently.

  • Cost per unit:

  • If $298$ units of the elliptical were produced, the fabrication cost is distributed among these units.

  • Divide the total allocated fabrication cost by the number of units produced to find the per-unit cost for that activity.
    $Cost \text{ per unit} = \frac{\text{Total Fabrication Cost}}{\text{Units produced}} = \frac{36,414}{298} \approx 122.19 \text{ per unit}$
    Corrected calculation with the updated total cost.

  • Treadmill Example: A similar calculation process is applied to treadmills, using their specific machine hours and the same fabrication rate to determine their allocated fabrication cost per unit. For instance, if the treadmill's calculation results in $174.11$ per unit, it follows the same methodology.

New Company Example: Light Fixture Manufacturer

• Activities Involved: This example highlights a broader range of activities typical in manufacturing beyond basic production.

  • Casting the metal lamp: Involves molding molten metal into the desired shape for the lamp components.

  • Assembly: The process of putting together the cast metal parts, electrical components, and other decorative elements to form the complete light fixture.

  • Quality Inspection: Comprehensive checks to ensure the structural integrity, electrical safety, and aesthetic quality of the light fixtures.

  • Number of Setups: Tracks the frequency of machine and line reconfigurations needed for different light fixture designs or production batches.

  • Materials Handling: Activities related to moving raw materials, work-in-process, and finished goods throughout the factory, which includes receiving, storing, issuing, and transporting.

Budget Activity Costs

• Example Costs: These represent the total estimated costs for specific activity pools over a budget period.

  • Total budgeted cost for the Casting activity pool: $343,000$.

  • The Casting activity base (cost driver) is Machine hours, with a total budgeted $5,100$ machine hours for a specific product line, such as 'Entry Lights'.

  • Activity Rate for Casting (Entry Lights): This rate is specific to the 'Entry Lights' product line, allocating the budgeted cost based on machine hours directly consumed by it.
    $Activity \text{ Rate} = \frac{\text{Total Cost}}{\text{Machine Hours}} = \frac{343,000}{5,100} \approx 67.25 \text{ per machine hour}$

  • Combined Rate for Both Lights (Entry and Dining): If the casting department serves multiple products, a consolidated rate might be used after combining total costs and total activity for all products. If the total machine hours for both light types is $9,790$, then:
    $\text{Combined Rate} = \frac{\text{Total cost for both activities}}{\text{Total Machine Hours}} = \frac{343,000}{9,790} \approx 35.04 \text{ per Machine Hour}$ (rounded to nearest cent, as in the original note's text).

Formatting in Excel

• Key points for working in Excel for financial reporting:

  • Merging Cells: This feature allows combining multiple cells into one larger cell, typically used to create clear, centered titles or labels that span across several columns, enhancing report readability.

  • Wrapping Text: This function automatically adjusts the row height to display all content within a cell, preventing text from being truncated or overflowing into adjacent cells, which is vital for displaying long descriptions or notes clearly.

Activity Rate Calculation

• The example for calculating activity rates applies to all activities required for both types of lights (Entry and Dining), ensuring a comprehensive cost allocation model.

  • Assembly: The same calculation technique (Total Budgeted Cost $\div$ Total Budgeted Activity Driver) is applied to determine the assembly activity rate, using an appropriate cost driver like direct labor hours or number of units assembled.

  • Quality Inspection: For instance, if the total budgeted cost for quality inspection is $26,000$ and the total number of inspections is $2,130$, the rate per inspection is:
    $\frac{26,000}{2130} \approx 12.21 \text{ per inspection}$

• There are ongoing discussions within the company regarding the strategic choice of outsourcing parts production versus in-house manufacturing, driven by potential cost savings and efficiency gains.

Real-World Application Discussion

• The discussion extends to real-world examples of companies strategically using outsourcing for various production components. For instance, Microsoft's decision to outsource the manufacturing of its Xbox consoles is a key example, illustrating how outsourcing can be essential to manage production costs, leverage specialized manufacturing capabilities, and scale production efficiently to meet global demand, ultimately impacting product pricing and market competitiveness.

Hypothetical Scenario Development

• Engaging students in thinking of global companies and their production strategies, such as unraveling the specific manufacturer processes behind complex technology products like Nintendo consoles or Microsoft devices. This exercise aims to foster critical thinking about global supply chains, manufacturing complexities, and the strategic decisions companies make in product development and production.

Costs and Operations in Production

• It is critically important to manage activity costs effectively in direct comparison to the profits generated from products. This involves continuously monitoring cost drivers and optimizing processes to maximize profit margins.

• There is a continuous need to evaluate the balance between producing commercial (e.g., large-scale, industrial) and residential (e.g., consumer-focused, household) products, as each category often has different cost structures, market demands, and profitability profiles. Strategic decisions are made based on this ongoing evaluation.

Discussion on Management Decisions

• This section emphasizes the crucial role of management in evaluating and making informed decisions based on the outcomes of cost analysis. Understanding cost drivers and allocated costs is foundational for strategic planning.

• There is an encouragement to critically analyze differing method options for cost allocation, such as using a single plant-wide overhead rate versus implementing multiple departmental rates or a more detailed activity-based costing (ABC) system. Each method has its advantages and disadvantages concerning accuracy, complexity, and decision-making utility.

Cost Control in Healthcare

• Activity-based costing (ABC) can be directly related to managing operational costs in hospitals and other healthcare facilities. It helps in detailing specific expenses associated with various services rendered to patients.

• This includes meticulously tracking costs associated with hospital admissions (e.g., administrative, room care), X-rays (e.g., equipment depreciation, technician time, consumables), surgeries (e.g., surgeon fees, anesthesiology, surgical supplies, operating room usage), and technical support (e.g., IT systems, biomedical equipment maintenance).

Impact of Selling and Administrative Expenses

• Identifying how to effectively allocate selling and administrative (S&A) expenses using activity-based costing is also crucial. S&A costs are often indirect but significant and can greatly impact product profitability.

• This includes noting specific challenges faced in product management (e.g., marketing campaigns, product development oversight) and customer service support post-sale (e.g., call center operations, warranty claims, technical assistance, returns processing), where ABC can help attribute these costs more accurately to specific products or customer segments.

Example Breakdown of Costs in Hospital Operations

• A detailed breakdown of hospital costs effectively shows how the efficiency and quality of service delivery directly impact the hospital's profitability. By understanding the true cost of each procedure or patient stay, hospitals can identify areas for cost reduction and process improvement.

• Real-world applications further demonstrate how refined pricing models, informed by accurate cost data from ABC, can be developed not only to cover costs but also to address and meet customer (patient) expectations regarding transparency, value, and quality of care, ultimately influencing patient satisfaction and competitive positioning.
