Abstract
This thesis project is the focus of our final year MIE496Y1Y thesis course. The purpose of the thesis course is to allow students to pursue an area of technical interest. Our group, composed of two Industrial Engineering students, is interested in the Lean Six Sigma approach and has decided to work on a Lean Six Sigma project at a wireless mobile manufacturing company. Lean Six Sigma is an overall quality improvement approach combining and capitalizing the strengths of Six Sigma and Lean Management improvement programs. In completing this thesis project, our goal is to acquire extensive knowledge on the approach and apply it to improve the quality of an assembly operation process of a wireless mobile manufacturing company facility. This thesis report will document the work that we have accomplished in the past eight-and-a-half months on this project. The emphasis is placed in 3 areas: Familiarization with the Lean Six Sigma methodology Critical analysis of two published case studies of Lean Six Sigma application Our case work on the implementation of the methodology in improving the assembly operations at the wireless mobile manufacturing company We have made use of our developed knowledge from our research and literature review in carrying out the case project on the wireless mobile manufacturing company. The objective is to minimize the number of process defects and optimize the efficiency of the assembly operation. The DMAIC (Define-Measure-Analyze-Improve-Control) approach was followed to identify the causes of this problem, measure the process capability, analyze the potential causes of demoted quality, implement improvements and control the process such that long-term improvements can be sustained. We have proposed a capable process model with minimal process variation. Lean tools and techniques will be employed to achieve the efficient use of resources and to minimize non-value added activities in the process.
