Abstract

The purpose of this paper is to demonstrate uses and application of quality engineering in general and Taguchi methods in particular in Ethiopian Plastic Share Company (EPSC) main processes. As a methodology, secondary data from the company has been collected and used to identify process variation and their associated losses. In addition, this data has been an input to conduct the experiment. The result clearly shows that the uses of design of experiment to parameter design ensure about 90% reduction of the company’s losses. Often the company’s management associated these losses to the employee’s technical capability. This conforms with Deming’s teaching that 80-90% of an organization’s problems are attributed to the parameter design than the employees. 


Key Words: Quality Engineering, Taguchi’s Method, Design of Experiment, Taguchi’s Loss Function, Orthogonal Array
