The document shows a diagram that illustrates the relationship between a company's service level, total costs, and cost of lost sales. As a company's level of customer service increases from 0% to 100%, total costs including transportation, order processing, and inventory carrying costs also increase in a positive relationship. However, the cost of lost sales from not meeting customer needs decreases as service level improves. The diagram provides a visual representation of this relationship to help businesses understand how improving customer service affects total costs.
