Certain Products Such as Gasoline and Diesel Engines Require Very

Multiple Choice

Certain products such as gasoline and diesel engines require very precise drilling. Tolerances are extremely small, and drill bits that can accomplish the near-perfect drills are very expensive. Unfortunately, the drill bits must be discarded after only a few drills as they sustain distortions that cause them to exceed the tight tolerances. Feng Zu invented a new method to sharpen high performance metal drill bits to their original specifications. Feng's process meant that companies could extend the life of drill bits. Feng knew that his invention would be a success, but he needed to find the users of high-performance drill bits and direct personal sales calls to them. Using NAICS Feng was frustrated because, for example, he could compile only very general lists of potential users and many on the lists would not be users of drill bits at all. Feng needed a service that would provide much more specific information about business firms in order to determine if they were really potential customers. Which of the following services would likely help Feng?

A) VALS
B) the Gallup Poll
C) PRIZM
D) Dun's Market Identifiers
E) ESRI's Tapestry^TM Segmentation
