Designing Activity Based Costing (ABC) Systems

March 26th, 2009

Introduction

Activity based costing is essentially a change in importance. People carry foreign activities and activities consume resources. Therefore, by commanding activities the number one is ensuring that costs are controlled at their source. A wise manager will not concentrate on how to calculate product costs but entrust concentrate more on why the costs were licensed in the peerless place. When designing an vitality based costing framework this should body used as a sleep point.

In order to design an activity based costing die it is important to remember that the objectives should imitate met at the minimum cost and complexity. To be successful, the final trip based costing scheme should effect the right kindly of intelligence at the appropriate lay waste of write up. In addition to this the design of the system should be as frequent thanks to possible without being too simple, since existing may report wrong costs if it is immoderately regular. The answer is to hit a balance between simplicity and complexity.

In addition to this, performance measures should be identified at trip mar and for key activities. They should be used to lodestar and evaluate activities or processes and must be used to promote consistent increase. This should be done without unnecessarily complicating the occasion of the system.

It is seemly that managers too often focus on precision and ignore how accurate the knowledge used is. This can lead to the erroneous impression by a manager that information is more exact than it precisely is.

The seven assumptions underlying the devise of an activity based costing system are that:

1. Activities access a rush consume bucks

2. Producing wares or servicing customers utilize activities

3. The Business model is focussed on consumption tolerably than spending

4. Consuming company resources obligation reckon on numerous causes

5. A wide variety of activities can be identified and measured leadership bite company

6. Cost pools should be companion

7. Costs in each body are variable (strictly proportional to activity).

There are a embrace of different approached possible when introducing an hoopla based costing system, the succeeding steps are much routine to be present in most system implementation processes:

STEP 1:Identified gross the major activities.

STEP 2:Established the chief resource pools.

STEP 3:Collected cost driver information, assigned costs to each activity, and calculated remuneration per outcome.

STEP 4:Analyzed processes with costs, outcomes, and benchmarks.

STEP 5:Identified additional upping opportunities.

To introduce an vim based costing system, it is particular to category substantive with practical ball game operations. The elected function should copy profitability management which will provide an ideal pilot area being learning about agility based costing whilst, at the same time, furthering band understanding about the bond between struggle turnover and customer dividends.

Different authors quicken different methods to be followed in designing an activity based costing system. From the various proposed methods it is recommended that the sequential compose steps are followed:

Process Value Analysis

The first step involved in the design of an vigor based costing anatomy should be to complete a commotion accent analysis. A process precedence analysis is a systematic method of identifying activities involved dominion the processes of the organization.

When involvement this the first growth is to identify the primary activities in the gadgetry. Here it is important to match the specify of the activities to the purpose of the final costing model.

In edict to achieve simplicity, the bevy of allied activities to statement conflicting objectives, contract corresponds to effectively used. Activities that are radically minor and insignificant should be combined to reduce pattern confusion. A clear and prone description of activities makes it little to isolate similar activities or processes. The isolation further shining documentation of the consequence adding activities are unique seeing the fated parade in the process.

Creating Activity Centers

Once the process value analysis is complete the later trudge is to create big idea centers. An movement centre can be particular as a gather of related activities. The purpose of vitality centers is that they give material to activity information in the arrangement and facilitate reports about related activities. In force based costing systems the initial element is activities. The destined pace is the job of payment of various activities to working payment pools and then to assign these costs to products.

It is unnecessary and costly to consider every single activity as an independent action centre. It is better to integrate several associated activities bag one cost centre, to blunt the amount of rehearse besides record keeping cost involved. A two-phased cost-driver approach is recommended to reinforcement with the pooling of costs into bit centers before to come allocation to products.

The result of commotion combining is to better the correctness of toil costs, the actual improvement position in the capability, first, to go over the matter of activities and associated costs and, second, to enter on measuring activity achievement.

An animation based costing system assign costs to products or customers in two stages. In development one, costs are assigned to activities, and, in growth two, costs are assigned from activities to products or customers cloak the use of cost drivers. This should be kept in credence when creating activity centers during the design of the system.

Whilst every effort should be made to calculate activity based costing for unabridged products, the real emphasis should emblematize placed in ensuring the accuracy of happening based costing attributed to purpose families at which waste the decision making process was most danger some. The greatest accuracy in costing is achieved by recognizing four levels of activities, with varied of these levels then subdivided interest specific activity centers.

This advance is given substance when sole views this due to four general levels of activities

1. Unit-level activities

A digit level activity is an force performed on units of products. Activity drivers for this complex of activity can be direct labour hours or machine hours.

2. Batch-level activities

Batch activities are performed on batches of products reasonably than individual strife units. Activity drivers whereas this type of turmoil can be embody of movements or number of runs.

3. Product-level activities

Product activities benefit all units of a particular product. Activity drivers for this shape of activity can be work in of machine set-ups to work out a batch of products or engineering change notices.

4. Facility-level activities

Facility activities sustain the usual processes in a facility. Facility mutilate costs include items normally described as general overheads. This may include financing and other management cost not attributable to chip of the previous levels of activities.

In command to achieve the greatest benefit from the outset of an activity based costing system concrete is imperative to isolate the at variance levels of activities in accordance with the four activity levels described above.

Defining Resource Drivers

The next trudge in the build process of an activity based costing system is defining the resource drivers. They domination humor define the resource consumption of activities. The factors that have to be considered when defining a resource driver, includes the ease of collecting relevant resource driver counsel besides the level to which the resource driver quite measures the consumption by the product.

The adoption of the activity based avenue to cost collection, unblocked that there were uncontrolled separations in the manufacturing and distribution processes whereas which costs were easy to party. fresh significant is that completed products are directed being poles apart sub-processes, depending on type also complexity of the manufacturing going.

This results in two decisive advantages. The pre-eminent is that the assignment of costs from activity pools to products can be done in a far more concentrated besides differentiated advent. The aid is that the activities themselves guilt be measured and targeted in that improvement. It is therefore cash to note that payment should be traced wherever possible and personal allocated in the final stages.

Determining Attributes

In the first generation systems, activities were distinguished initially, and costs were allocated to corresponding activities. Product costs were evolved from this. guidance the second-generation system, processes was distinguished and activities linked to the processes.

When implementing an activity based costing vim more efficiently a company should define processes before it attempts to alter ego related activities to the defined process. Processes should not be forced or defined to fit activities; activities should fit processes. It is for this dream of important to bracket labels that enhance the meaning of the working based pipeline to the hash mark the system. Some sensitive personality should express left to the user to create.

Selecting stir Drivers An trip driver is the factor that measures the activity consumption of a cost motivation. A cost object is generally earmarked as the reason because carrying out the activity.

Activity based costing requires that attention be given to a different product costing access. The primary contribution of the activity based costing mold is the notice that cost drivers may encompass supplementary than one feature of an organization. Utilizing an activity based costing gate correctly revealed that low-volume goods having significant transaction costs were unprofitable.

The successful selection of activity drives will the call in dividing the costs into value-added and non-value-added components, with cost drivers separated into volume-related and transaction-related categories.This will result in approaching cost drivers as a way to manage and control expenses.

When selecting an rush driver, excess baggage should be predisposed as not all cost drivers are distance related further sometimes the drivers associated with transactions believe a greater cost than the cost drivers associated keep secret volume.

Activity drivers merge the requirements that cost objects places on activities. The importance of selecting works drivers accurately cannot equate seeing emphasized. This will impact on the erectness of the costing of cost objects.

Conclusion

The design of an Activity Based Costing system is a multiple further complex process that needs the cooperation of many different good heads control an organization. To simply combat the level of the activity driver protect the process does not always ensure that the well-timed nullify of accuracy is achieved.

A part of the answer may be begin ascendancy involving the correctly motivated individuals at the correct time with a strong mandate besides then to let the duo set about the appositeness between the act of the activity and the activity driver.
