Traditional vs. innovative practices

In the late 1980s, accounting practitioners and educators were heavily criticized on the grounds that management accounting practices (and, even more so, the curriculum taught to accounting students) had changed little over the preceding 60 years, despite radical changes in the business environment. Professional accounting institutes, perhaps fearing that management accountants would increasingly be seen as superfluous in business organizations, subsequently devoted considerable resources to the development of a more innovative skills set for management accountants.

The distinction between ‘traditional’ and ‘innovative’accounting practices can be illustrated by reference to cost control techniques. Cost accounting is a central method in management accounting, and traditionally, management accountants’ principal technique was variance analysis, which is a systematic approach to the comparison of the actual and budgeted costs of the raw materials and labor used during a production period.

While some form of variance analysis is still used by most manufacturing firms, it nowadays tends to be used in conjunction with innovative techniques such as life cycle cost analysis and activity-based costing, which are designed with specific aspects of the modern business environment in mind. Life-cycle costing recognizes that managers’ ability to influence the cost of manufacturing a product is at its greatest when the product is still at the design stage of its product life-cycle (i.e., before the design has been finalized and production commenced), since small changes to the product design may lead to significant savings in the cost of manufacturing the products. Activity-based costing (ABC) recognizes that, in modern factories, most manufacturing costs are determined by the amount of ‘activities’ (e.g., the number of production runs per month, and the amount of production equipment idle time) and that the key to effective cost control is therefore optimizing the efficiency of these activities. Activity-based accounting is also known as Cause and Effect accounting.

Both lifecycle costing and activity-based costing recognize that, in the typical modern factory, the avoidance of disruptive events (such as machine breakdowns and quality control failures) is of far greater importance than (for example) reducing the costs of raw materials. Activity-based costing also deemphasizes direct labor as a cost driver and concentrates instead on activities that drive costs, such as the provision of a service or the production of a product component.
