Abstract
This study looks on the integration of lean six sigma in a manufacturing company and how the whole sector of manufacturing implement the methodology of lean six sigma .the cross functional relationship between total quality management ,product quality and kaizen on how does lean six sigma integrate the relationship that exist between these methodologies .hence the need to look on the phases that needs to be followed in order to implement lean six sigma in a manufacturing company and detailed discussion of the lean six sigma techniques that are applied in manufacturing with the benefits of this techniques that are frequently applied are discussed in this study .This research report performs a qualitative study where interviews were conducted in a manufacturing company and descriptive questionnaires were sent to individuals within the manufacturing sector while using quantitative data to substantiate findings .
According to the findings from the conducted interviews, it was discovered that most of the participants are aware of the lean six sigma methodology and have experience in the methodology while the minority of the participants have little nor no knowledge of the methodology .a conclusion on the review of literature was identified that most manufacturing companies do apply lean six sigma and reviewed the techniques that are frequently used by this sector and a recommendation of closed-loop supply chain was made to the manufacturing company with the conceptual framework and the guideline on implementation of the recommended methodology in order to solve the research problem of improving the process performance by applying this lean six sigma technique in the manufacturing company .
