Dr. Goldratt says it this way: “If a process of ongoing improvement is what we are after, which of the three avenues of Throughput, Inventory, or Operating Expense is more promising? If we just think for a minute the answer becomes crystal clear. Both Inventory and Operating Expense we strive to decrease. Thus, both of them offer limited opportunity for ongoing improvement. Both of them offer only limited opportunity for ongoing improvement. They are both limited by zero. This is not the case with the third measurement, Throughput. We strive to increase Throughput. Throughput does not have any intrinsic limitation; Throughput must be the cornerstone of any Process Of On-Going Improvement (POOGI). It must be first on the scale of importance.”
Therefore, to make decisions according to Theory of Constraints (TOC) and Throughput Accounting, we need to quantify a decision’s impact on these three measurements and then we will be able to determine the change in net profit and return on investment.
The role of the company’s constraint is fundamental for quantifying the decision’s impact on the three measurements. Thus, to identify which products contribute the most to the company’s net profit, TOC also advocates the use of the measurement of “Throughput per time of the constraint (T/CU)”. This method is much simpler than the product costing and it allows for fast decisions that are directly linked to the bottom line.
