Özet:

Companies invest a lot of time and money to obtain a “better” estimate of product cost. However, Theory of Constraints (TOC), a management philosophy developed by Dr. Eliyahu M. Goldratt, has demonstrated that estimated product cost values are meaningless and in no way guarantee correct decisions. Problem is not due to bad allocation, but to allocation itself. It is important for everyone to understand that the goal of a company is not to decrease unit costs but to increase company profit and that the two objectives are not the same. Efforts to decrease unit costs harm the company by increasing inventory carrying cost, expediting and overtime costs and product lead-time. Throughput accounting, a prerequisite to a successful TOC implementation, requires little data to calculate the change in Throughput, Operating Expense and Investment. Without a need to determine product costs, Throughput Accounting leads to an increase in company profit by allowing correct decisions in all problems involving product portfolio selection, new product evaluation, product pruning, product price determination, machine investments, and make/buy alternatives. The purpose of this article is to introduce this management philosophy to our country and to promote its overdue application in Turkish companies.
