Activity-based costing emerged as an important accounting concept in the mid-1980s in response to global competition. There is an urgent need to place it in perspective, so that both production and marketing managers know its advantages and its limitations. This book describes and explains where activity-based concepts fit in the cost and management accounting body of knowledge. It first shows the traditional framework of cost concepts, terminology and techniques in order to demonstrate how the activity-based methods can bring about constructive changes in financial control systems. The major feature of the book is the three ABC models for manufacturing processes, marketing functions, and service industries. These models are based on the Institute of Management Accounting (IMA)-sponsored case studies of corporate divisions or branches by Harvard professors, Cooper and Kaplan, and KPMG Peat Marwick. The book also includes illustrations of the most important cost analysis and control techniques that every successful operating manager must know.
