8. Enables fast and inexpensive model
maintenance.
9. Supplies granular information to assist
users with identifying the root cause of
problems.
10. Can be used in any industry or company
with complexity in customers, products,
channels, segments, and processes and
large amounts of people and capital
expenditures.
Despite some possible theoretical inferiority; it
is correct that TDABC implementation is
much simpler than ABC in that it requires only
two parameters, the unit cost of activity and
the time required to perform a transaction or
an activity. As such, TDABC is very suitable
for a service company such as a hotel, because
hotel activities are primarily measured on the
basis of labour time used for performing a
given activity, or have high portion of
overhead cost. The use of traditional cost
system to determine the rooms selling price
not only causes inflexibility; but also many
people argue overcome the subjectivity in their
cost driver selections. Also, often the price
cannot reflect the changing circumstances.
Hopefully by using TDABC, the cost
calculations can be more precise and also more
flexible with the changing environmental
circumstances.
Kaplan and Anderson (2007) outline the
two steps in implementation this system as
follows:
“First, it calculates the costs of supplying
resource capacity . . . . it divides this total
cost by the capacity of the department to
obtain the capacity of the department to
obtain the capacity cost rate. Second,
TDABC uses the capacity cost rate to drive
departmental resource costs to cost objects
by estimating the demand for resource
capacity (typically time, from which the
name of the new approach was chosen)
that each cost object requires.”
The essential components of TDABC in its
implementation stage are namely (Kaplan
and Anderson 2007):
1. Define activities, activity costs pools
and activity measures.
