Throughput Accounting: Theory of Constraints Dr. Goldratt's 'Throughput Accounting' revolutionized the methods by which companies viewed their costs and associated them with profits. Unlike the traditional cost accounting methods, Goldratt argues that accounting should seek to maximize the movement of products through an organization to eliminate potential bottlenecks that prevents efficiency and speed. Goldratt argues that the current costing systems in use were developed almost a hundred years ago based upon the business practices and business designs of that particular era. The traditional accounting system therefore can be understood in the context of a "Cost World". This cost world focuses all aspects of business value and decision making upon the cost of products themselves. In order to connect all of the subsequent aspects of business to costs, very elaborate allocation of expenses had to flow through to products. These "cost schemes" in effect have many different error s and assumptions that impacts the accuracy of accounts and therefore causes misjudgments within management decision making. Goldratt proposes within his book that accounting should be viewed through a "throughput" perspective. Throughput rests upon three specific elements: throughput, inventory and operating expense. Throughput can be defined as the monetary gain a business makes from selling its products. Investment is the monetary value of all fixed assets which enables throughput to occur. Finally, operating expense is all of the operational expenses spent on producing throughput. The reasoning behind Goldratt's analysis for the need of throughput accounting is that the world is no longer based upon flat delineations of costs. Businesses today, unlike the last century, do not commit the majority of their resources on factors, plants and other vehicles of heavy capital investment. Even more important, workers were thought of as variable costs because they were mostly low-skilled and thus easily varied through workforce demand. In today's world, these two moving forces, resources and labor are moving in opposite directions. Resources are becoming much more variable and formerly fixed costs are becoming flexible as a result of changing workflows. At the same time, skilled labor especially in key high skilled industries are becoming much more fixed and necessary than before as well. Thus, allocation of costs to labor or specific products is no longer accurate and rests on faulty assumptions. The foundational principle of Godratt's throughput accounting is that decisions are focused upon the goals of the organization rather than on its costs. All of the decisions made by the business can be related to their ultimate goal. Under this accounting system, individuals are viewed as assets rather than expenses, and traditional mechanisms of inventory and throughput are carefully analyzed and reconfigured to align with organizational goals. Goldratt argues that there are three fundamental relationships established through throughput accounting mechanisms, these are described below. Throughput accounting at the core is the "summation of all the gain from sales of all the individual products" (NOTATION): T= i p T p (p=individual products) This is the first principle of throughput accounting. At the same time, Operating expense is the summation of the individual subsets of operating expense. This would include all subsets of operating expense including employees and their manager resources, interest levels, energy costs, etc. OE = i c OE c (c=individual categories) The role of cost accounting within financial analysis was to develop a mechanism to search for a very good estimation in understanding how production lines impact each other and thus impacts the net profitability of companies. Goldratt argues that cost accounting was intended to make "apples and oranges into apples and apples". This would allow compan ies to have a true metric for cross-comparison. Throughput accounting solves the problem of allocation simply by dividing a company into product by product classes. It uses the formula: NP = i p (T - OE) p The reason that Throughput accounting is necessary according to Goldratt is that cost accounting has become too ineffective in forming solutions for modern corporate problems and diversification. Concepts such as cost drivers and activity based costing are both ineffective in their methodology in truly assessing corporate profit and stakeholders. These above principles make up the foundation of Godratt's Throughput Accounting analysis.By focusing upon the mechanisms for consistent business improvement, Throughput Accounting works
