Evolution of Cost Accounting and Management Systems
The Stage of Truth Conditional Cost
During the 1960s, Cost Accounting began to recover its identity following a series of significant social and economic events. These included the pursuit of an optimum economy, the rise of mass consumption, and the launch of the first communications satellites, which represented a breakthrough in media and the expansion of multinational corporations. Organizations realized that the cost of a product was not an absolute truth. Consequently, Cost Accounting focused on the determination of various models and techniques that could provide different types of costs for different purposes, allowing it to become independent of Financial Accounting.
The Stage of Truth as Expensive Cost
In the 1970s, companies sought to quantify both costs and benefits more effectively. Cost was conceptualized as "truth as expensive," acknowledging that the expense incurred to obtain accurate and timely information must be compared with the value or utility of such information for company managers.
The Positive Approach Stage
During the 1980s, a positive approach emerged, seeking to implement a general theory to manage existing knowledge and skills. In this phase, cost was viewed as a "realized truth." This period was marked by developments in organizational conduct, the delegation of responsibilities, and interdisciplinary collaboration.
The Crisis of Traditional Cost Systems
A variety of factors completely transformed the competitive environment for American manufacturers. Inflation rates decreased, and a sharp increase in the value of the dollar lowered the competitiveness of American products against foreign goods. Simultaneously, a manufacturing revolution led by Japanese firms introduced innovative management practices, including:
- Total Quality Management (TQM)
- Just-in-Time (JIT) inventory systems
- Computer Integrated Manufacturing (CIM)
These practices, combined with new technology, reduced direct labor costs and ensured Japanese products offered excellent value for money.
Modern Management Systems and Globalization
Political, economic, and social changes have led to the globalization of markets and increased environmental uncertainty. As competition grew and consumer demands became more selective, traditional cost techniques from the early 20th century became obsolete. New cost management systems emerged, supported by digital technology. Key modern management techniques include Just-in-Time, Total Quality Management, and Activity Based Costing (ABC).
