Introduction

Activity Based Costing (ABC) addresses internal operating concerns and is an augmentation to the traditional cost management system. It is not a replacement for traditional accounting, but makes use of the source documents provided from standard job costing systems. ABC looks at a business unit’s events as cost drivers and assigns all company resources and accumulated costs against those events in a time-phased sequence. Revenue tracking provides management with a different point of view on the profitability of products and services, providing insight into pricing. Middle management and technical performing organizations are involved in the line item reporting provided within the ABC system, enabling management to achieve more responsibility of reported information throughout all levels of the organization. ABC is being ostensible by the accounting industry as the wave of the future and is gaining broad acceptance within larger organizations. This system is intended to provide performing entities and management alike.

History of ABC
Activity Based Costing (ABC) is an approach to costing that considers the resources consumed by activities in order to create and deliver a product or service. It evolved in the mid-1980s to improve the allocation of manufacturing overhead costs to products, but it soon became apparent that activity-based costing systems could be expanded to include non-manufacturing costs (Langfield-Smith, Thorne & Hilton, 2004).

Review of ABC
Whereas the underlying assumption of a conventional costing system is simply that products cause costs, an activity based costing system assumes that cost objects (e.g. juice) creates the demand for activities (e.g. manufacturing), which in turn causes resources to be consumed (e.g. manufacturing time, outlet space, etc.) and causes costs. Cost objects are the reason for performing activities, and activities are the processes or procedures that cause work and create costs.
