Purpose of the article:
To describe a two-stage structured approach to implementing activity-based cost
systems.
First stage:
Decision-making. Involves design choices that should be made before starting the
implementation. These choices will define the characteristics of the system and
will depend on its primary objective.
- Should the system be integrated with
the existing system or should it be a stand-alone system
?
Factors to consider: a) time, b) cost (software development, interfaces, how
frequently is info. needed), c) corporate approval, d) approval from external
auditors e) expertise.
- Should a formal design be approved
before implementation?
Factors to consider: a) time
involved in design-approval process, b) dealing with design changes during
data-gathering and analysis phases of project.
- Who should take ownership of the
final system?
Factors to consider: a) only
finance people involved or a multidisciplinary team.
- How precise should the system be
?
Factors to consider: a) use of
information generated by system.
- Should the system report historical
or future costs
?
Factors to consider: a) use of
information generated by system.
- Should the initial design be complex
or simple
?
Factors to consider: a) risks
involved in building a) complex system, b) objective of the system
Second stage: Implementation.
Objectives of this stage: a) ensure implementation team has adequate knowledge
of ABC to allow the team to design an appropriate system, b) ensure management
learns the concepts and benefits of ABC so they will accept and use the info.
generated by system, c) ensure that the design and data gathering steps of
project will be performed efficiently.
The
implementation plan used involved 7 steps:
- Seminar on ABC for the management team.
- Design seminar for the implementation
team-computer-based training exercises, which dealt with how to identify
activity centers and methods to assign costs, as well as how to collect data.
- Design and data gathering-analyze
overhead to identify the activities driving it.
- a) identify major activities
- b) determine the cost of those
activities
- c) identify what drives those
activities
- d) determine quantities of each
cost driver associated with each product
- e) compute activity-based product
costs
Overhead was broken into 6 major
components: a) salaried wages, b) indirect hourly wages, c) maintenance
& repair, d) depreciation and taxes, e) fringe benefits, and f) other
resources.
- Progress meetings-informational
meetings with management about the progress made throughout the design and
data-gathering steps. Plant managers played an important role by providing
feedback about the info. obtained, helping to identify possible errors made
by the design team, and providing solutions to problems encountered by the
team.
- Executive seminar for the management
team-more detailed info. about ABC, the final design of the system was
presented, management’s concerns about discrepancy in product costs
between 2 systems was discussed, dissemination of info. generated by new
system was discussed.
- Results meeting-select group
analyzed activity-based info. generated by system to fine-tune system
results.
- Interpretation meetings-how to
interpret the activity-based product costs and the actions that should be
taken based on that info. Engineers gave feedback about how the costs were
assigned to products. Also, discussions about finding ways to improve the
production process to reduce costs took place.
