Question:

In 1985, a company called In-Process Technology was set up to produce and sell a thermal oxidation process that could be used to reduce industrial pollution. The initial investors acquired the rights to technology developed at the U.S. Department of Energyâ€™s Lawrence Livermore National Laboratory to more efficiently convert energy in burners, process heaters, and others. For several years, the company performed dismally and by 1991 was only earning $264,000 annually.

Discussion

1. Thermatrix has grown and flourished because of its good customer relationships, which include partnering, delivering a quality product on time, and listening to the customerâ€™s needs. Suppose company management wants to formally measure customer satisfaction at least once a year and develops a brief survey that includes the following four questions. Suppose 115 customers participated in this survey with the results shown. Use techniques presented in this chapter to analyze the data to estimate population responses to these questions.

2. Now suppose Thermatrix officers want to ascertain employee satisfaction with the company. They randomly sample nine employees and ask them to complete a satisfaction survey under the supervision of an independent testing organization. As part of this survey, employees are asked to respond to questions by providing a score from 0 to 50 along a continuous scale where 0 denotes no satisfaction and 50 denotes the upmost satisfaction. Assume that the data are normally distributed in the population.
