Synopsis:  There are many types of curves used in business. Unfortunately, many of them present an incomplete picture. Sales curves should not be confused with Adoption curves; they tell different stories. The objective of this chapter is to convince you to require proper sales curves that best project the success or failure of a product. The map for this chapter is at the end. To recognize the value of this map, and what it presents, it is important to first understand what it is not. This requires a number of illustrations that demonstrate some of the many ways sales data is presented. Presentation has an enormous influence on what is communicated and how effectively it is conveyed.
