Activity based management is a system wide,integrated approach that focuses management 's attention on activities with the objective of improving customer value and the profit achieved by providing this value. Activity based costing is a major source of information for activity based management . Thus, the activity based management model has two dimensions: a cost dimension and a process dimension . This two dimension model is presented in exhibit 5-1 . The cost dimension provides cost information about resources,activities,and cost objects of interest such as product,customer,suppliers, and distribution channels . The objective of the cost dimension is improving the accuracy of cost assignments. As the model suggests,the cost of resources is traced to activities, and then the cost of activities is assigned to cost objects . This activities based costing dimension is useful for product costing , strategic cost management , and tactical analysis. The second dimension, the process dimension, provides information about what activities are performed, why they are performed , and how well they are performed . This dimension's objective is cost reduction. It is this dimension that provides the ability to engage in and measure continuous improvement.
