Despite its theoretical superiority over
traditional volume-based costing models, the
Activity-Based Costing (ABC) modelhas failed
to replace traditional volume-based costing
models in most organisations. In response to
the problems of the model, Time-Driven
Activity-Based Costing (TDABC) and
Resource Consumption Accounting (RCA)
models have been developed as costing models
for next generation cost management systems.
A key feature that distinguishes TDABC and
RCA models from traditional volume-based
costing models and the ABC model is the
recognition of idle resources in resource pools.
