Using six sigma as a problem-solving methodology for senior design projects

Abstract

Senior design projects require students to demonstrate the integrated application of their industrial engineering skills, knowledge, and tools learned throughout their curriculum. At University of San Diego (USD), projects involve identifying and solving a real life problem in the field of industrial engineering. For many students, however, the unstructured nature of these projects present new challenges. "What problem solving methodology can I use to solve an unstructured problem?" Six Sigma is a proven process improvement methodology used in industry for solving problems. The Six Sigma philosophy and methodology started at Motorola in the 1980's has gained popularity in industry is based on the DMAIC model which contains five steps: Define, Measure, Improve, and Control. The DMAIC method provides the framework to improve the capabilities of an existing process by reducing variation, defects, or even costs. The DMAIC is a structured problem solving methodology that incorporates a majority of the process improvement tools introduced throughout an Industrial Engineering student's career at the university. The DMAIC methodology can provide students with the framework and structure necessary to successfully complete an open ended project within the specified timeframe. The paper presents how the DMAIC methodology has been incorporated into the senior design project at USD.
