One of the most important concepts of The Goal is to increase throughput. Throughput is the rate at which the system generates money through sales. That is, when your company takes raw materials, processes them into a finished good, and sells it, the measured rate of that activity is your throughput. Severe emphasis on sales. Throughput is not the same as efficiency. Today, we will look at throughput vs. efficiency and how these concepts apply to IT.

Though we are focusing on throughput, we must state the descriptions of the two other measurements. Inventory is all the money that the system has invested in purchasing things which it intends to sell. Operational expense is all the money the system spends in order to turn inventory into throughput. I list the three definitions together because the definitions are precise and interconnected. Changing even a single word in one requires the other two be adjusted as well.
