Activity Based Costing - Management Accounting | CMA Inter Syllabus - 4

1. Traditional Cost System

Under traditional cost system, overheads costs are first allocated and apportioned to various production and service departments and after that the overheads costs of service departments are re-apportioned to various production departments and once the same are done then finally overheads costs of production departments are absorbed to the cost objects (products, customer) on the basis of labour hours, machine hours, prime cost, direct materials costs and direct wages costs, etc. The principle involved is that the finished products consume the resources in proportion to production volume.

The traditional cost accumulation system of absorption costing was developed at a time when most organisations produced only a narrow range of products (so that products underwent similar operations and consumed similar proportions of overheads). The overhead costs were only a very small fraction of total costs.
The benefits of more accurate systems for overhead allocation would probably have been relatively small. In addition, information processing costs were high.
In recent years, however, there has been a dramatic fall in the costs of processing information, and with the advent of advanced manufacturing technology (AMT), overheads are likely to be far more important and in fact direct labour may account for as little as 5% of a product’s cost. Therefore, now it appears difficult to justify the use of direct labour or direct material as the basis for absorbing overheads or to believe that errors made in attributing overheads will not be significant.
Many resources are used in non-volume related support activities, (which have increased due to AMT) such as setting-up, production scheduling, inspection and data processing. These support activities assist the efficient manufacture of a wide range of products and are not, in general, affected by changes in production volume. They tend to vary in the long term according to the range and complexity of the products manufactured rather than the volume of output.
The wider the range and the more complex the products, the more support services will be required. Consider, for example, factory X which produces 10,000 units of one product, the Gama, and factory Y which produces 1,000 units each of 10 slightly different versions of the Gama. Support activity costs in the factory Y are likely to be a lot higher than in factory X, but the factories produce an identical number of units. For example, factory X will only need to set-up once, whereas Factory Y will have to set-up the production run at least ten times for the ten different products. Factory Y will therefore incur more set-up costs for the same volume of production.
Traditional costing systems, which assume that all products consume all resources in proportion to their production volumes, tend to allocate too great a proportion of overheads to high volume products (which cause relatively little diversity and hence use fewer support services) and too small a proportion of overheads to low volume products (which cause greater diversity and therefore use more support services).

  • Overhead rate based on volume and its limitations:

      Volume-Based Overhead Rate

The factory overhead rate in a volume-based costing system is either a single over-head rate for the entire operation (plant wide rate) or a set of overhead rates with various rates for different departments or divisions (department rates). These overhead rates use an output-volume-based activity or activities to assign (or to spread) factory overhead costs to products or services. An output-volume-based costing system spreads costs evenly so that each cost object (product or service) receives the same amount.

  • Illustration 1 (Applying the overhead absorption rate)

Let us now recap the various overheads rates that are used in the context of absorption of overheads costs to the products/ jobs/ customer/ work-order, etc.
There are several different methods which can be used to absorb overheads. The following data to determine the total production cost of job number M 626:

Total cost centre overhead  ₹62,100
Production output 13,800 units
Direct labour hours  27,000 hours
Machine hours 34,500 hours 
Direct wages cost ₹17,250
Direct materials cost ₹49,680
Prime Cost ₹66,930

  • Illustration 2

A Company is manufacturing two products, Product A and Product B and the annual outputs of the two products are 10,000 units and 20,000 units respectively. Total annual overheads of the company is ₹3,00,000. The machine hours required for Product A are 20,000 hours and that of Product B are 10,000 hours, respectively. Then the overhead absorption rates under traditional costing system, using machine hours as the basis can be computed, as under:

NO.. Particulars Product A Product B
1.  Annual Outputs (units) ₹10,000 ₹20,000
2. Total Machine Hours  ₹20,000 ₹10,000
3. Overhead Absorption Rate on the basis of Machine Hours (Total Overheads/ Total Machine Hours) = (₹3,00,000/30,000) = ₹10 per hour    
4. Total Overheads Costs on the basis of machine hours (No. of machine hours × Rate per machine hour)  ₹2,00,000 ₹1,00,000
5. Overheads Cost per unit (4 ÷ 1) ₹20 ₹5

 

From the above, the following inferences can be made for the Traditional Cost System:

     a. The finished products consume resources in proportion to the production volume.
     b. The proper identification of value added and non-value added activities cannot be made.
     c. It does not facilitate the control over those activities, which cause fixed overhead costs.
     d. A Single/ Blanket rate is used to absorbs the overheads costs to the cost objects, causing cost distortion.
     e. It is a subjective approach, since this system uses arbitrary bases for apportionment of overheads costs over the cost objects.

2. Definition and Meaning of Activity Based Costing

Activity-based costing is an effective costing system that focuses on activities. ABC is a refined costing system, or a more specific way to assign costs to cost objects. The system avoids using big, generic categories, such as splitting a cost evenly between divisions. Instead, it allocates indirect costs to the activities that generate those costs. The result is likely to be more accurate costing and product pricing.

ABC Basic Premises: 

  • Cost objects consume activities.
  • Activities consume resources.
  • This consumption of resources is what derives costs.

ABC emphasizes the importance of linking indirect costs to activity in the cost allocation exercise. It argues that cost is derived from activities. When there are more activities, more costs will be incurred. Based on this logic, cost should be allocated according to the activities that drive costs to the cost object. Cost objects are the defined objects for allocation of indirect costs, e.g., product portfolio, customers, or business units. Cost pools are the costs gathered to serve similar functions, e.g., production, marketing units, and finance department. Cost drivers are the key attributes or proxies which are the causes of spending, e.g., no. of purchase orders for purchase department, service hours for engineering department, and no. of employees for human resource units. Cost drivers serve as allocation base for allocation of cost to cost objects, and the degree of costs allocated rests with the level of activity (in terms of the consumption base). Using this allocation method, cost can be more accurately allocated to the cost object.
Activity-based costing plays an important role in companies’ strategies and long-range plans to develop a competitive cost advantage. While activity - based costing focuses attention on activities in allocating overhead costs to products, activity-based management focuses on managing activities to reduce costs. Cost reduction generally requires a change in activities. Top management can send notices to company employees to reduce costs, but the implementation requires a change in activities. An entity cannot know the effect of a change in activities on costs without the type of cost information provided by activity-based costing.
Activity-Based Costing (ABC) is that costing in which costs begin with tracing of activities and then to producing the product. In other words, it is the process of costing system which focuses on activities performed to produce products. This system assumes that activities are responsible for the incurrence of costs and products creates the demand for activities. Costs are charged to products based on individual product’s use of each activity.
ABC aims at identifying as many costs as possible to be subsequently accounted as direct cost of production. Any cost that is traced to a particular product via its consumption of activity becomes direct of the product. For instance, in conventional costing system, cost of setup and adjustment time is considered as factory overhead and subsequently assigned to different products on the basis of direct labour hours, but in Activity-Based Costing, set-up and adjustment time is determined for 
each product and its costs are directly charged to each product. Thus, by emphasizing activities, ABC tries to ascertain the factors that cause each major activity, cost of such activities and the relationship between activities and products produced.
Activity-Based Costing had its genesis in the increasing importance of indirect costs in the manufacturing operations. The direct processing costs which are easier to handle are being relegated to the background with each passing day due to automation. In this changing scenario where indirect costs outweigh the direct processing costs in many a situation, one cannot be content with rough and ready methods of dealing with indirect costs.
The concept of ABC was first defined in the late 1980s by Robert Kaplan and William Burns. Initially ABC focused on manufacturing industry where technological developments and productivity improvements had reduced the proportion of direct labour and material costs, but increased the proportion of indirect or overhead costs. ABC is generally used as a tool for understanding cost and profitability of individual products.
ABC costing will enable management to better understand the cause of costs, and from here action can be taken to control and reduce costs through controlling and reducing the demand for cost causing activities.
According to CIMA Official Terminology, Activity Based Costing is ‘An approach to the costing and monitoring of activities which involves tracing resource consumption and costing final outputs. Resources are assigned to activities, and activities to cost objects based on consumption estimates. The latter utilize cost drivers to attach activity costs to outputs.’
An ABC system assigns overheads to each major activity (rather than departments). With ABC systems, many activity-based cost centres (alternatively known as activity cost pools) are established, whereas with traditional systems overheads tend to be pooled by departments, although they are normally described as cost centres.
Activities consist of the aggregation of many different tasks, events or units of work that cause the consumption of resources. Typical support activities include: schedule production, set-up machines, move materials, purchase materials, inspect items, process supplier records, expedite and process customer orders. Production process activities include machine products and assemble products. Within the production process, activity cost centres are sometimes identical to the cost centres used by traditional cost systems. Support activities are also sometimes identical to cost centres used by traditional systems, such as when the purchasing department and activity are both treated as cost centres. Overall, however, ABC systems will normally have a greater number of cost centres compared with traditional systems.
The second stage of the two-stage allocation process allocates costs from cost centres (pools) to products or other chosen cost objects. Traditional costing systems trace overheads to products using a small number of second stage allocation bases (normally described as overhead allocation rates), which vary directly with the volume produced. Instead of using the terms ‘allocation bases’ or ‘overhead allocation rates’ the term ‘cost driver’ is used by ABC systems. Direct labour and machine hours are the allocation bases that are normally used by traditional costing systems. In contrast, ABC systems use many different types of second-stage cost drivers, including non-volume-based drivers, such as the number of production runs for production scheduling and the number of purchase orders for the purchasing activity

  • Emergence of Activity-based Costing

The purpose of moving from a traditional costing system to an ABC system must be based on the premise that the new information provided will lead to action that will increase the overall profitability of the business. This is most likely to occur when the analysis provided under the ABC system differs significantly from that which was provided under the traditional system, which is most likely to occur under the following conditions:

        (i) When production overheads are high relative to direct costs, particularly direct labour.
        (ii) Where there is great diversity in the product range.
        (iii) Where there is considerable diversity of overhead resource input to products.
        (iv) When consumption of overhead resources is not driven primarily by volume.

Information from an ABC analysis may indicate opportunities to increase profitability in a variety of ways, many of which are long term. For example, an activity-based analysis often reveals that small-batch items are relatively expensive to produce, and are therefore unprofitable at current prices. A number of responses to this information could be adopted. The first response might be to consider stopping production of such items, and concentrate on the apparently more profitable high-volume lines. Another approach would be to investigate how the production process could be organized in such a way as to bring the cost of producing small-batch items closer to that of producing high-volume goods. By identifying the cost of carrying out particular activities, the new approach provides opportunities for directing attention to matters of cost control. It can therefore be viewed as a much longer-term technique then the word ‘costing’ in the title suggests. The establishment of an ABC product cost may thus be considered to be merely the beginning of a process, rather than an end in itself. The recent use of the term activity-based management suggests this forward-looking orientation, which is assuming increasing importance.
Traditional product costing systems were designed when most of the companies manufactured a narrow range of products. Direct materials and direct labour were the dominant factors of production then. Companies were in the sellers’ market. Overheads were relatively small and distortions due to inappropriate treatment were not significant. Cost of processing information was high.
Today, companies produce a wide range of products. Overheads are of considerable importance Simple methods of apportioning overheads based on direct labour are not justified. Intense global competition calls for correct costing of products to avoid errors in decision-making. Traditional systems can measure volume related costs. Non-volume related activities like material handling, set-up etc. are important and their costs cannot be apportioned on volume basis. Hence, the need for emergence of activity based costing arises.

3. Steps in ABC System

  • Steps in ABC System

1. To identify the different activities within the organisation. Usually the number of cost centres that a traditional overhead system uses is quite small, say up to 15. In ABC the number of activities will be much more, say 200; the number will depend on how the management subdivides the organisation’s activities. It is possible to break the organisation down into many very small activities, but if ABC is to be an acceptable and practical system it is necessary to use larger groupings, so that, say, 40 activities may be used in practice. The additional number of activities over cost centres means that ABC should be more accurate than the traditional method.
2. To determine what causes the cost of each activity – the cost driver (e.g. machine hours; number of dispatch orders).
3. To calculate the total cost for each activity – the cost pool (e.g. total machining costs; total costs of dispatch department).
4. To calculate an overhead absorption rate for each cost driver.
5. Activity Cost Driver Rate = Total Cost of an Activity / Cost Driver                                                             
6. To calculate the total overhead cost for each product manufactured.
7. To calculate the overhead cost per unit for each product.

  • Meaning of Activities

Activities comprise of units of work or tasks. For example, purchase of materials is an activity consisting a series of tasks like purchase requisition, advertisement inviting quotations, identification of suppliers, placement of purchase order, follow - up, etc.

  • Value Added Activities
  • These are activities necessary for the performance of the process.
  • These represent work that is valued by the external or internal customer.
  • They improve the quality or function of a product. Hence, the customers are usually willing to pay for the service. VA activities result in ‘Cost’ and not in losses.
     Example: Making product more versatile for certain other uses.
  • Non-Value Added Activities
  • These are additional and extraneous activities, not fully necessary for the performance of the process.
  • These represent work that is not valued by the external or internal customer.
    NVA activities do not improve the quality or function of a product or service but they can adversely affect costs and prices. NVA activities create waste, result in delay of some sort, add cost to the products or services for which the customer is not willing to pay.
    Example: Moving materials and machine set up for a production run.

Manufacturing activities can be classified along a cost hierarchy dimension consisting of:

       a. Unit-level activities;
       b. Batch-level activities;
       c. Product-sustaining activities;
       d. Facility-sustaining activities.

In the following lines the above mentioned activities are discussed:

a. Unit-level activities (also known as volume-related activities) are performed each time a unit of the product or service is produced. Expenses in this category include direct labour, direct materials, energy costs and expenses that are consumed in proportion to machine processing time (such as maintenance). Unit-level activities consume resources in proportion to the number of units of production and sales volume. For example, if a firm produces 10 per cent more units it will consume 10 per cent more labour cost, 10 per cent more machine hours and 10 per cent more energy costs.
Typical cost drivers for unit level activities include labour hours, machine hours and the quantity of materials processed. These cost drivers are also used by traditional costing systems. Traditional systems are therefore also appropriate for assigning the costs of unit-level activities to cost objects.
b. Batch-related activities, such as setting up a machine or processing a purchase order, are performed each time a batch of goods is produced. The cost of batch-related activities varies with the number of batches made, but is common (or fixed) for all units within the batch. For example, set-up resources are consumed when a machine is changed from one product to another. As more batches are produced, more set-up resources are consumed. It costs the same to set-up a machine for 10 or 5000 items. Thus, the demands for the set-up resources are independent of the number of units produced after completing the set-up. Similarly, purchasing resources are consumed each time a purchasing order is processed, but the resources consumed are independent of the number of units included in the purchase order. Other examples of batch-related costs include resources devoted to production scheduling, first-item inspection and materials movement. Traditional costing systems treat batch-related expenses as fixed costs, whereas ABC systems assume that batch-related expenses vary with the number of batches processed.
c. Product-sustaining activities or service-sustaining activities are performed to enable the production and sale of individual products (or services). These activities are performed to support the production of each different type of product. Maintenance of equipment, engineering charges, testing routines, maintaining bills of materials etc. are the few examples of product level activities.
d. The final activity category is facility-sustaining (or business-sustaining) activities. They are performed to support the facility’s general manufacturing process and include general administrative staff, plant management and property costs. They are incurred to support the organisation as a whole and are common and joint to all products manufactured in the plant. There would have to be a dramatic change in activity, resulting in an expansion or contraction in the size of the plant, for facility-sustaining costs to change. Such events are most unlikely in most organisations. Therefore, these costs should not be assigned to products since they are unavoidable and irrelevant for most decisions. Instead, they are regarded as common costs to all products made in the plant and deducted as a lump sum from the total of the operating margins from all products.

  • Cost Object:

It is an item for which cost measurement is required e.g. a product or a customer.

4. Cost Pools and Cost Drivers

  • Cost Pool: 

The term cost pools are used to describe a location to which overhead costs are initially assigned. Normally cost centres consist of departments, but in some cases they consist of smaller segments such as separate work centres within a department. A cost pool is a grouping of individual costs, typically by department or service center. Cost allocations are then made from the cost pool. For example, the cost of the maintenance department is accumulated in a cost pool and then allocated to those departments using its services.
Cost pools are commonly used for the allocation of factory overhead to units of production, as required by several accounting frameworks. They are also used in activity-based costing to allocate costs to activities. A business that wants to allocate costs at a highly-refined level may choose to do so using a number of cost pools.

The various Cost Pools may be as under in a manufacturing company:

a. Purchasing Department
b. Receiving Department
c. Material Handling
d. Set-up of Machines
e. Inspection and Quality Control
f. Research and Developments
g. Customer Service
h. Production Control

  • Cost Driver:

It is a factor that causes a change in the cost of an activity.

  • Categories of cost driver:
  • Resource Cost Driver
    It is a measure of the quantity of resources consumed by an activity. It is used to assign the cost of a resource to an activity or cost pool. For example, number of purchase orders placed will influence the cost of materials to be purchased.
  • Activity Cost Driver:
    It is a measure of the frequency and intensity of demand, placed on activities by cost objects. It is used to assign activity costs to cost objects. Activity cost drivers can be transaction drivers (e.g. No. of purchase orders processed, no. of customer orders processed, etc.) as well as duration drivers (it represent amount of time required to perform an activity e.g. Setup hours, inspection hours, etc.)
  • Volume Based Cost Drivers
    They assume that a product’s consumption of overhead is directly related to units produced i.e. in case of Machine hours, if volume is increased by 10%, machine hours will increase by 10% hence energy cost will increase by 10%.
  • Non-Volume Based Cost Drivers
    They are in contrast of volume based cost drivers. Non-volume based activities are not performed each time a unit of the product or service is produced e.g. number of production runs for production scheduling & the number of purchase orders for the purchasing activity.

Some Cost Drivers that are used in the context of Activity Based Costing:

  • Number of requisitions rose
  • Number of machine set-up
  • Number of machine hours
  • Number of production runs
  • Number of processed orders
  • Number of purchase orders
  • Number of orders completed
  • Number of labour hours
  • Number of orders packed and delivered
  • Number of inspections
  • Number of customers visit, etc.
  • Cost object:

It is an item for which cost ascertainment is required. For example, a product, a service, a job, a work order no, or a customer, etc.

  • Applications of ABC:

The numbers of uses to which an ABC system can be put are only limited by the imagination of the user. Here are some of its more common applications:

  • When an ABC analysis is combined with a review of investment costs for various tactical or strategic options, one can determine the return on investment to be expected for each of the investment options.
  • An ABC system can accumulate all of the costs associated with a particular distribution method, which allows managers to compare this cost to the profit margins earned on sales of products that are sold through it. One can then determine if the distribution channel should be reconfigured or eliminated in order to improve overall levels of profitability.
  • An ABC analysis will itemize the costs of each plant, and correctly allocate these costs to the activities conducted within them, which allows a company to determine which plants are more efficient than others.
  • An ABC analysis includes all activity costs associated with a manufactured item, which yields a comprehensive view of all costs associated with it, and which can then be more easily compared with the cost of a similar item that is purchased.
  • By using internal ABC analyses to determine the cost of various activities, a company can create a benchmark for what these costs should be in potential acquisition targets. If the targets have higher costs than the benchmark levels, then the acquiring company knows that it can strip out costs from the acquisition candidate by improving its processes, which may justify the cost of the acquisition.
  • An ABC analysis can reveal the cost of each activity within an organisation. The system is really designed to trace the costs of only the most significant activities, but its design can be altered to itemize the costs of many more activities. This information can then be used to determine which activities are so expensive that they will be the main focus of management attention, or which can be profitably combined with other activities through process centering. This is a primary cost-reduction activity.
  • An ABC analysis reveals all of the costs associated with a product, and so is useful for determining the minimum price that should be charged. However, the actual price charged may be much higher, since this may be driven by the ability of the market to absorb a higher price, rather than the underlying cost of a product.
  • An ABC analysis can be combined with product prices to yield a list of margins for each product sold. When sorted by market, product line, or customer, it is easy to see which products have low or negative returns, or which yield such low margin volume that they are not worth keeping.
  • An ABC analysis can reveal which activities contribute to the completion of products, and which do not. Then, by focusing on non-value-added activities, a company can create significant improvements in its profitability.
  • An ABC analysis reveals the cost of anything that a management team needs to know about—activities, products, or customers—which can then be sorted to see where the highest-cost items are located. When combined with a value analysis, one can determine what costs return the lowest values, and structure a cost-reduction effort accordingly.
  • An ABC analysis can itemize the costs that are specific to each customer, such as special customer service or packaging issues, as well as increased levels of warranty claims or product returns. When added to the margins on products sold to customers, this reveals which customers are the most profitable after all costs are considered.

5. Merits and Demerits of ABC System

  • Merits of ABC:

   a. ABC recognizes the increased complexity of modern businesses with its multiple cost drivers, many of which are transaction based rather than volume based.
   b. ABC is concerned with all overhead costs, including such ‘non-factory floor’ costs as quality control and customer service, and so it takes cost accounting beyond its ‘traditional’ factory floor boundaries.
   c. ABC gives a meaningful analysis of costs which should provide a suitable basis for decisions about pricing, product mix, design and production.
   d. ABC helps with cost reduction because it provides an insight into causal activities and allows organisations to consider the possibility of outsourcing particular activities, or even of moving to different areas in the industry value chain.
   e. ABC can be used in conjunction with customer profitability analysis (CPA) to determine more accurately the profit earned by serving particular customers.
   f. ABC can be used by service and retail organisations. Many service and retail businesses have characteristics very similar to those required for the successful application of ABC in modern manufacturing industry.

The main advantages of ABC can further be summarized under the following points:

a. To link the cost to its causal factor – i.e. the Cost Driver
b. To identify costs of activities rather than cost centres
c. To ascertain product costs with greater accuracy by relating overheads to activities
d. To overcome the inherent limitations of traditional absorption costing and use of blanket overhead rates
e. To assist managers in budgeting and performance measurement
f. To provide the links between the activities, the organizational acts and the resources consumed, and illustrate the differences between resource consumption and resource provision
g. To help in cost control and cost reduction, as well as improved profitability.
h. To provide valuable economic information to support a company’s operational improvement and customer satisfaction programs.
i. To furnish many significant benefits over traditional costing techniques:
    (i) most accurate data about product cost;
    (ii) more comprehensive cost information for performance measurement;
    (iii) relevant data for management’s decision-making;
    (iv) more potential for sensitivity analysis;
    (v) providing a model prospect on value-adding organizational transactions and activities.

ABC can be applied most effectively in the following situations:

    (i) A highly competitive market
    (ii) Diversity of products, processes and customers
    (iii) Significant overhead costs which are not easily assigned to individual products
    (iv) Demands placed on overhead resources by individual products and customers, which are not proportional to volume.

  • Demerits of ABC:

The demerits of ABC are as follows:

  a. The cost of obtaining and interpreting the new information may be considerable. ABC should not be introduced unless it can provide additional information for management to use in planning or control decisions.
  b. Some arbitrary cost apportionment may still be required at the cost pooling stage for items like rent, rates and building depreciation. If an ABC system has many cost pools, the amount of apportionment needed may be greater than ever.
  c. Many overheads relate neither to volume nor to complexity. The ability of a single cost driver to fully explain the cost behaviour of all items in its associated pool is questionable.
  d. There will have to be a trade-off between accuracy, the number of cost drivers and complexity.
  e. ABC tends to burden low-volume (new) products with a punitive level of overhead costs and hence threatens opportunities for successful innovation if it is used without due care.
  f. Some people have questioned the fundamental assumption that activities cause cost; they suggest that decisions cause cost or the passage of time causes cost or that there may be no clear cause of cost.

The main drawbacks of ABC can also be summarized under the following points:

  a. Implementing an ABC system requires substantial resources, which is costly to maintain.
  b. Activity Based Costing is a complex system which needs lot of record for calculations.
  c. In small organisation mangers are accustomed to use traditional costing systems to run their operations and traditional costing systems are often used in performance evaluations.
  d. Activity based costing data can be easily misinterpreted and must be used with care when used in decision making. Managers must identify which costs are really relevant for the decisions at hand.
  e. Reports generated by these systems do not conform to generally accepted accounting principles (GAAP). Consequently, an organisation involved in activity based costing should have two cost systems - one for internal use and one for preparing          external reports.

6. Activity Based Information and Decision Making

  • Use of ABC in Decision Making
  1. For decisions like relocation or opening of a new distribution center, reduction in freight or other logistics costs can offset the expense of a new facility, staff or equipment. ABC system can identify the specific cost elements being targeted, providing a much clearer picture according to which management can decide and act accordingly.
  2. ABC is a complement to Total Quality Management (TQM) and it provides quantitative data that can track the financial impact of improvements implemented as part of the TQM initiative.
  3. Using traditional absorption system, overheads may get distributed equally across all product lines. ABC system traces the costs back to the activity and the consumption of resources by each product. This helps in analyzing the costs and profits of existing and new products in a more realistic manner.
  4.  ABC can augment decision support for human resources. ABC can present a number of options, including outsourcing, productivity improvements through automation and determination of employee/revenue ratios.

Further the areas in which Activity based information is used for decision making are as under:

  • Product line profitability
  • Capital Investment decisions
  • Transfer Pricing
  • Pricing of products
  • Market Segmentation and Distribution Channels
  • Make-or-Buy decisions and outsourcing
  • Plant shut-down decisions
  • Evaluation of off-shore production, etc.

ABC supports corporate strategy in the following manner: 

  • Accurate information on product costs enables better decisions to be made on pricing, marketing, product design, product mix etc.
  • Performance based accurate feedback can be provided to cost center managers.
  • ABC system can effectively support the management by furnishing data, at the operational and as well as strategic level.
  • ABC system can change the method of evaluation of new process technologies, to reduce setup times, proved plant layout and thereby lowering material handling costs, quality improvement.

ABC supports corporate strategy in many ways such as:

  • ABC system can effectively help the management by furnishing data at the operational level and strategic level.Accurate product costing will help the management to compare the profits that various customers, product lines, brands or regions generate and to decide on pricing strategy, dropping unprofitable products, lines etc.
  • Information generated by ABC system can also encourage management to re-design the products for improving their quality.
  • ABC systems can change the system of evaluation of new process technologies, to reduce setup times, rationalization of plant layout in order to reduce or lower material handling cost, improve quality etc.
  • ABC analysis helps managers focus their attention and energy on improving activities.
  • The cost driver rates established by ABC system can be used to measure activity performance and efficiency and provide a more suitable basis for budgeting.
  • The accurate feedback can be provided to cost center managers on their performance based on their consumption of resources during a period rather than the allocations of cost over which they have no control.
  • ABC system provide accurate information on product costs which enables better decisions to be made on pricing, marketing, product design and product mix.
  • When to use ABC?

In discussing the question ‘Does your company need a new cost system?’ Cooper suggested that the managers should ask themselves ‘Do I really know what my products cost?’ If the answer to this question is ‘no’, he urged that managers should consider whether it is necessary to undertake a detailed analysis of their cost accounting system, but rather than undertaking a major and costly analysis in every case, he suggested that managers look for the following symptoms which are indicative of a need for ABC:

  • Products that are very difficult to produce are reported to be very profitable, even though they are not premiumpriced. Cooper argues that products are difficult to produce should be expected to cost more and, therefore, to be profitable only if they are priced at a premium.
  • Profit margins cannot be easily explained. If managers believe certain products to be more profitable than the accounting system suggest, it may be necessary to analyze costs using ABC.
  • Some products, not sold by competitors, have high reported margins. Competitors would normally be expected to produce products, which are more profitable. Why are they not producing these products? They may consider the cost to be too high. It calls for examining of the costing system.
  • Competitors’ high volume products are priced at apparently unrealistically low levels. If competitors are able to price their products at levels, which appear unrealistically low, it may be that the firm’s costing system needs examining.
  • Suppliers offer to produce parts at prices considerably lower than expected.
  • Managers considering buying in parts currently produced internally who find that suppliers offer them at unexpectedly low prices should examine their costing systems.
  • Cost pools are too large and contain machines that have very difficult overhead structures. This creates considerable complexity and could mean that the procedures for allocating the overheads will be too simplistic.
  • The cost of marketing and delivering the products varies dramatically by distribution channel, and yet the cost accounting system effectively ignores marketing costs.

Managers should look for these symptoms and ask themselves whether they have confidence in their product costinformation. As symptoms may have other explanations, it is important to consider: the range of possibilities and to evaluate which is more likely. However, even if it appears that, existing product costs are misleading it may not always be necessary to incorporate ABC into the accounting system. It must be remembered that the introduction of the ABC system involves major expense and thus managers must ask themselves whether the benefits to be derived from the superior information exceed the cost of the new accounting system.
In the present industrial scenario, it becomes difficult in the industry to survive unless the overhear costs are correctly accounted for, controlled and reduced so as to sustain, remain and grow in the industry. We cannot reduce the direct cost of the product, (unless materials of cheaper value are used) but we can control very much the overheads. This can be done only when one has the information of the cost centers with respect to function or activity. The overhead costs involved, for a product do not usually give a clear picture so as to control and reduce these costs. Therefore, it becomes necessary to have a costing system based on activity done, because of this need for ABC arises. Thus ABC has a wide scope in the context of cost reduction and cost control.
It may be made clear that ABC cannot be applied where a distinction cannot be made for the costs attached to various activities or functions. Implementation of ABC should be made from shop floor to managerial level. If ABC is applied correctly at the correct place and time, the company can attain more profits than before.
Although the activity based approach looks attractive, it is unlikely to be practical to relate all overheads to specific activities. Moreover, the approach implicitly assumes a sense co-operative behaviour among operating units and between operating units and service functions. It does not acknowledge the possibility of conflict over the allocation process of overheads. Apart from their narrow concern over efficiency and optimal profitability, the advocates of activity based approach have not attempted to explain why firms insist on using simple methods of allocation of overheads.
However, ABC system has been widely implemented in large organisations in US and Europe. ABC system can be successfully used in other segments of the organisation i.e., administration, selling, distribution etc. It can equally be applied in service sectors like banks, insurance, hospitals and other institutions providing services.
ABC has the same objectives in service firms as in manufacturing organisations. ABC can prove very useful to many service organizations such as airlines, insurance companies, banks, hospitals, hotels, railways, financial service firms. In these service organisations, managers need accurate information about the cost of services being provided by them. Further, such service firms require using this information to improve their operations and to fulfill the needs of their customers in a more cost effective manner.

Large-scale service organizations have a number of features that have been identified as being necessary to derive significant benefits from the introduction of ABC:

     (i) They operate in a highly competitive environment;
     (ii) They incur a large proportion of indirect costs that cannot be directly assigned to specific cost objects;
     (iii) Products and customers differ significantly in terms of consuming overhead resources;
     (iv) They market many different products and services.

The uses for ABC information for service industries are similar to those for manufacturing organisations:

     (i) It leads to more accurate product costs as a basis for pricing decisions when cost-plus pricing methods are used;
     (ii) It results in more accurate product and customer profitability analysis statements that provide a more appropriate basis for decision-making;
     (iii) ABC attaches costs to activities and identifies the cost drivers that cause the costs. Thus, ABC provides a better understanding of what causes costs and highlights ways of performing activities more effectively by reducing cost driver                            transactions. Costs can therefore be managed more effectively in the long term. Activities can also be analyzed into value added and non-value added activities and by highlighting the costs of non-value added activities attention is drawn to                  areas where there is a potential for cost reduction without reducing the products’ service potentials to customers.

Large service organisations, such as Insurance, Banks and Hospitals, used to be noted for their lack of standard costing systems, and their relatively unsophisticated budgeting and control systems compared with large manufacturing organisations. But this is changing and many large service organisations are now revising their use of management accounting techniques.

  • Requirements:

a. Explain which features of large-scale service organisations encourage the application of activity-based approaches to the analysis of cost information.
b. Explain which features of service organisations may create problems for the application of activity-based costing.
c. Explain the uses for activity-based cost information in service industries.
d. Many large service organisations were at one time state-owned, but have been privatized. Examples in some countries include electricity supply and telecommunications. They are often regulated. Similar systems of regulation of prices by an independent authority exist in many countries, and are designed to act as a surrogate for market competition in industries where it is difficult to ensure a genuinely competitive market.

Explain which aspects of cost information and systems in service organisations would particularly interest a regulator, and why these features would be of interest.

Hamid & Co, make laptop computers for use in dangerous environments. The company’s main customers are organisations like oil companies and the military that require a laptop that can survive rough handling in transport to a site and can be made to their unique requirements.
The company started as a basic laptop manufacturer but its competitors grew much larger and RL had to find a niche market where its small size would not hinder its ability to compete. It is now considered one of the best quality producers in this sector.
Hamid & Company had the same finance director for many years who preferred to develop its systems organically. However, due to fall in profitability, a new chief executive officer (CEO) has been appointed who wishes to review Hamid’s financial control systems in order to get better information with which to tackle the profit issue.
The CEO wants to begin by thinking about the pricing of the laptops to ensure that selling expensive products at the wrong price is not compromising profit margins. The laptops are individually specified by customers for each order and pricing has been on a production cost plus basis with a mark-up of 45 per cent. The company uses an absorption costing system based on labour hours in order to calculate the production cost per unit.
The main control system used within the company is the annual budget. It is set before the start of the financial year and variances are monitored and acted on by line managers.
The CEO has been reading about major companies that have stopped using budgets and wants to know how such a radical move works and why a company might take such a step. He has been worried by moves by competitors into Hamid’s market with impressive new products. This has created unrest among the staff at Hamid with two experienced managers leaving the company.
